ITEM 1. Business

OVERVIEW

We are a diversified, multi-national healthcare enterprise that provides a portfolio of services to government sponsored and commercial healthcare programs, focusing on under-insured and uninsured individuals. We provide member-focused services through locally based staff by assisting in accessing care, coordinating referrals to related health and social services and addressing member concerns and questions. We also provide education and outreach programs to inform and assist members in accessing quality, appropriate healthcare services. We believe our local approach, including member and provider services, enables us to provide accessible, quality, culturally-sensitive healthcare coverage to our communities. Our health management, educational and other initiatives are designed to help members best utilize the healthcare system to ensure they receive appropriate, medically necessary services and effective management of routine, severe and chronic health problems, resulting in better health outcomes. We combine our decentralized local approach for care with a centralized infrastructure of support functions such as finance, information systems and claims processing.

In September 2017, we signed a definitive agreement under which Fidelis Care will become our health plan in New York State. Under the terms of the agreement, we will acquire substantially all of the assets of Fidelis Care for $3.75 billion , subject to certain adjustments.

We operate in two segments: Managed Care and Specialty Services. Our Managed Care segment provides health plan coverage to individuals through government subsidized and commercial programs including Medicaid, the State Children’s Health Insurance Program (CHIP), Long-Term Services and Supports (LTSS), Medicare, Foster Care, Supplemental Security Income Program, also known as the Aged, Blind or Disabled, or collectively ABD, and Medicare-Medicaid Plans (MMP), which cover beneficiaries who are dually eligible for Medicare and Medicaid. In addition, our commercial operations, which include our members through the Health Insurance Marketplace, are included within the Managed Care segment. Our Specialty Services segment consists of our specialty companies offering diversified healthcare services and products to state programs, correctional facilities, healthcare organizations, employer groups, military service members and their families, and other commercial organizations, as well as to our own subsidiaries. For the year ended December 31, 2017 , our Managed Care and Specialty Services segments accounted for 95% and 5% , respectively, of our total external revenues.

Our membership totaled 12.2 million as of December 31, 2017 . For the year ended December 31, 2017 , our total revenues and net earnings from continuing operations attributable to Centene were $48.4 billion and $828 million , respectively, and our total cash flow from operations was $1.5 billion .

Our initial health plan commenced operations in Wisconsin in 1984. We were organized in Wisconsin in 1993 as a holding company for our initial health plan and reincorporated in Delaware in 2001. Our corporate office is located at 7700 Forsyth Boulevard, St. Louis, Missouri 63105, and our telephone number is (314) 725-4477. Our stock is publicly traded on the New York Stock Exchange under the ticker symbol “CNC.”

INDUSTRY

We provide a full spectrum of managed healthcare products and services, primarily through Medicaid (which includes CHIP, LTSS, Foster Care, ABD and MMP), Medicare, and commercial products. We currently have operations domestically and internationally.

Medicaid

Established in 1965, Medicaid is the largest publicly funded program in the United States, and provides health insurance to low-income families and individuals with disabilities. Authorized by Title XIX of the Social Security Act, Medicaid is an entitlement program funded jointly by the federal and state governments and administered by the states. The majority of funding is provided at the federal level. Each state establishes its own eligibility standards, benefit packages, payment rates and program administration within federal standards. As a result, there are 56 Medicaid programs - one for each U.S. state, each U.S. territory and the District of Columbia. Eligibility is based on a combination of household income and assets, often determined by an income level relative to the federal poverty level. Historically, children have represented the largest eligibility group. Many states have selected Medicaid managed care as a means of delivering quality healthcare and controlling costs. We refer to these states as mandatory managed care states.  

Established in 1972 and authorized by Title XVI of the Social Security Act, ABD covers low-income persons with chronic physical disabilities or behavioral health impairments. ABD beneficiaries represent a growing portion of all Medicaid recipients. In addition, ABD recipients typically utilize more services as a result of their health status. 

The Balanced Budget Act of 1997 created CHIP to help states expand coverage primarily to children whose families earned too much to qualify for Medicaid, yet not enough to afford private health insurance. Costs related to the largest eligibility group, children, are primarily composed of pediatrics and family care. These costs tend to be more predictable than those associated with other healthcare issues which predominantly affect the adult population.

LTSS is a Medicaid product that covers Institutional/Residential Care (Nursing Facilities, Intermediate Care Facilities) and Home and Community Based Services (HCBS) for beneficiaries requiring assistance with their activities of daily living, such as bathing, dressing and transferring. The most common HCBS services include personal care, adult day care, non-emergent transportation, home-delivered meals and personal emergency response systems. LTSS services are provided for individuals requiring nursing home level of care, receiving waiver services, or entitled to state Medicaid LTSS benefits. The largest group receiving LTSS, by spending, are older individuals and individuals with physical disabilities ($98 billion in 2015), followed by individuals with intellectual and developmental disabilities ($44 billion in 2015), those with serious mental illness and/or serious emotional disturbance ($9 billion in 2015) and other populations ($7 billion in 2015). States are increasingly turning to managed care as a solution to provide coordinated, holistic care to their LTSS beneficiaries. According to the National Association of States United for Aging and Disabilities, 20 states utilize some form of LTSS up from eight in 2004.

The majority of youth and children in foster care qualify for Medicaid, most commonly through Title IV-E of the Social Security Act, which provides funding to support safe and stable out-of-home care for children who are removed from their homes. The federal government has enacted legislation establishing guidelines and requirements for state child welfare agencies related to the health and well-being of children in foster care, including the provision of grants and technical assistance to enable states to meet these needs and make explicit connections with state Medicaid. In addition, the Affordable Care Act requires states to make former foster care children eligible for Medicaid until they reach the age of 26, provided that they turned 18 while in foster care, and were enrolled in Medicaid at that time.

CMS estimated the total Medicaid market was approximately $566 billion in 2016, and estimated the market will grow to $929 billion by 2025. Medicaid spending increased by 3.9% in 2016 and is projected to increase at an average annual rate of 5.7% between 2017 and 2025.

While Medicaid programs have directed funds to many individuals who cannot afford or otherwise maintain health insurance coverage, they did not initially address the inefficient and costly manner in which the Medicaid population tends to access healthcare. Medicaid recipients in non-managed care programs typically have not sought preventive care or routine treatment for chronic conditions, such as asthma and diabetes. Rather, they have sought healthcare in hospital emergency rooms, which tends to be more expensive. As a result, many states have found that the costs of providing Medicaid benefits have increased while the medical outcomes for the recipients remained unsatisfactory.

We believe recognition of the value of managed care as a means of delivering improved health outcomes for Medicaid beneficiaries and effectively controlling costs will continue to strengthen. A growing number of states have mandated that their Medicaid recipients enroll in managed care plans. Other states are considering moving to a mandated managed care approach. As a result, we believe a significant market opportunity exists for managed care organizations with operations and programs focused on the distinct socio-economic, cultural and healthcare needs of the uninsured population and the Medicaid, CHIP, LTSS, Foster Care and ABD populations.

Medicare

We contract with CMS under the Medicare Advantage program to provide Medicare Advantage products directly to Medicare beneficiaries as well as through employer and union groups. We provide or arrange healthcare benefits for services normally covered by Medicare, plus a broad range of healthcare benefits for services not covered by traditional Medicare, usually in exchange for a fixed monthly premium per member from CMS that varies based upon the county in which the member resides, demographic factors of the member such as age, gender and institutionalized status, and the health status of the member. Any benefits that are not covered by Medicare may result in an additional monthly premium charged to the enrollee or through portions of payments received from CMS that may be allocated to these benefits, according to CMS regulations and guidance. Many of our Medicare Advantage members pay no monthly premium to us for these additional benefits.

We provide a wide range of Medicare products, including Medicare Advantage plans with and without prescription drug coverage and Medicare supplement products that supplement traditional fee-for-service Medicare coverage. Our subsidiaries have a number of contracts with CMS under the Medicare Advantage program authorized under Title XVIII of the Social Security Act.

A portion of Medicare beneficiaries are dual-eligible, low-income seniors and people with disabilities who are enrolled in both Medicaid and Medicare. According to CMS, there were approximately 10.7 million dual-eligible enrollees in 2017 . These dual-eligible members may receive assistance from Medicaid for benefits, such as nursing home care, HCBS, and/or assistance with Medicare premiums and cost sharing. Dual-eligibles also use more services due to their tendency to have more chronic health issues. We serve dual-eligibles through our ABD, LTSS, MMP and Medicare Advantage Dual Special Needs Plan lines of business.

CMS developed the Medicare Advantage Star ratings system to help consumers choose among competing plans, awarding between 1.0 and 5.0 stars to Medicare Advantage plans based on performance in certain measures of quality. The Star ratings are used by CMS to award quality bonus payments to Medicare Advantage plans. Beginning with the 2014 Star ratings (calculated in 2013), Medicare Advantage plans are required to achieve a minimum of 4.0 Stars to qualify for a quality bonus payment. The methodology and measures included in the Star ratings system can be modified by CMS annually and Star ratings thresholds are based on performance of Medicare Advantage plans nationally.

CMS estimated the total Medicare market was approximately $679 billion in 2016, and estimate the market will grow to approximately $1.3 trillion by 2025. Medicare spending increased 5.1% in fiscal 2016 and is projected to increase at an average annual rate of 7.3% between 2017 and 2025.

Commercial

W e offer commercial healthcare products to individuals and large and small employer groups as well as products to individuals through the Health Insurance Marketplace. Our health maintenance organization (HMO) plans offer comprehensive benefits generally for a fixed fee or premium that does not vary with the extent or frequency of medical services actually received by the member. We offer HMO plans with differing benefit designs and varying levels of co-payments at different premium rates. These plans are offered generally through contracts with participating network physicians, hospitals and other providers. When an individual enrolls in one of our HMO plans, he or she selects a primary care physician (PCP) from among the physicians participating in our network. Our preferred provider organization (PPO) plans offer coverage for services received from any healthcare provider, with benefits generally paid at a higher level when care is received from a participating network provider. Coverage typically is subject to deductibles and copayments or coinsurance. Our point of service (POS) plans and our elect open access (EOA) plans blend the characteristics of HMO, PPO and indemnity plans. Members can have comprehensive HMO-style benefits for services received from participating network providers with lower copayments (particularly within the medical group), but also have coverage, generally at higher copayment or coinsurance levels or with coverage limitations, for services received outside the network. Our Exclusive Provider Organization (EPO) plans and Healthcare Service Plans (HSPs) similarly blend elements of traditional HMO and PPO plans. 

In 2010, the Patient Protection and Affordable Care Act and the accompanying Health Care and Education Affordability Reconciliation Act, collectively referred to as the Affordable Care Act (ACA), were enacted. While the constitutionality of the ACA was subsequently challenged in a number of legal actions, in June 2012, the Supreme Court upheld the constitutionality of the ACA, with one limited exception relating to the Medicaid expansion provision (Medicaid Expansion). The Supreme Court held that states could not be required to expand Medicaid and risk losing all federal money for their existing Medicaid programs. Under the ACA, Medicaid coverage was expanded to all individuals under age 65 with incomes up to 138% of the federal poverty level beginning January 1, 2014, subject to the states' elections. The federal government paid the entire costs for Medicaid Expansion coverage for newly eligible beneficiaries from 2014 through 2016, and 95% of the costs in 2017. Assuming that the current program remains in effect unchanged, in 2018 the federal share is scheduled to decline to 94%; in 2019 it would be 93%; and it would be 90% in 2020 and subsequent years.

Health Insurance Marketplaces are a key component of the ACA and provide an opportunity for individuals and small businesses to obtain health insurance. States have the option of operating their own Marketplace or partnering with the federal government. States choosing neither option currently default to a federally-facilitated Marketplace. Premium and cost sharing subsidies are available to make coverage more affordable and access to Marketplaces is limited to U.S. citizens and legal immigrants. Insurers are required to offer a minimum level of benefits with coverage that varies based on premiums and out-of-pocket costs. Premium subsidies are provided to families without access to other coverage and with incomes between 100-400% of the federal poverty level to help them purchase insurance through the Marketplaces. These subsidies are offered on a sliding scale basis.  

International

We currently have a growing international presence in Spain and the United Kingdom. Our joint venture in Spain, Ribera Salud S.A. (Ribera Salud), is a health management group mainly operating in the health administrations concession sector. Ribera Salud also has other controlling and noncontrolling interests in Spain, Latin America, and Slovakia. In the United Kingdom, we own a controlling interest in The Practice (Group) Limited (TPG), one of the largest provider networks in the United Kingdom. TPG delivers medical and community based services in the primary care sector of the National Health Service (NHS), which is the publicly funded, national healthcare system for England.

OUR COMPETITIVE STRENGTHS

Our approach is based on the following key competitive strengths:

For the year ended December 31, 2017 , total revenues of $48.4 billion produced a five year Compound Annual Growth Rate (CAGR) of 43%.

  OUR BUSINESS STRATEGY

Key components of our current business strategy include: 

Substantially all of our revenues are derived from operations within the United States and its territories, and all of our long-lived assets are based in the United States and its territories. We generally receive a fixed premium per member per month pursuant to our state contracts. Our managed care subsidiaries in California and Texas had revenues from their respective state governments that each exceeded 10% of our consolidated total revenues in 2017 . In addition, the federal government is a significant customer to our Specialty Services segment due to our Federal Services business.

MANAGED CARE

Benefits to Customers

We feel that our ability to establish and maintain a leadership position in the markets we serve results primarily from our demonstrated success in providing quality care while reducing and managing costs, and from our specialized programs in working with state governments. Among the benefits we are able to provide to the states with which we contract are:

Member Programs and Services

We recognize the importance of member-focused delivery of quality managed care services. Our locally-based staff assists members in accessing care, coordinating referrals to related health and social services and addressing member concerns and questions. While covered healthcare benefits vary from customer to customer and program to program, our health plans generally provide the following services:

We also provide a comprehensive set of education and outreach programs to inform, assist and incentivize members to access quality, appropriate healthcare services in an efficient manner. Many of these programs have been recognized with awards for their excellence in education, outreach and/or case management techniques. These awards include Case In Point, Hermes Awards, U.S. Environmental Protection Agency and National Health Information Awards.

Providers

For each of our service areas, we establish a provider network consisting of primary and specialty care physicians, hospitals and ancillary providers. Our network of primary care physicians is a critical component in care delivery, management of costs and the attraction and retention of new members. Primary care physicians include family and general practitioners, pediatricians, internal medicine physicians and obstetricians and gynecologists. Specialty care physicians provide medical care to members generally upon referral by the primary care physicians. Specialty care physicians include, but are not limited to, orthopedic surgeons, cardiologists and otolaryngologists. We also provide education and outreach programs to inform and assist members in accessing quality, appropriate healthcare services. 

Our health plans facilitate access to healthcare services for our members primarily through contracts with our providers. Our contracts with primary and specialty care physicians and hospitals usually are for one to three-year periods and renew automatically for successive one-year terms, but generally are subject to termination by either party upon prior written notice. In the absence of a contract, we typically pay providers at applicable state or federal reimbursement levels, depending on the product (e.g., Medicaid or Medicare). We pay providers under a variety of methods, including fee-for-service, capitation arrangements, and value-based arrangements.

In addition, we maintain a network of qualified physicians, facilities, and ancillary providers in the prime service areas of our TRICARE contract. Services are provided on a fee-for-service basis. We also maintain a provider network in support of VA's Patient Centered Community Care (PC3) program.

We work with physicians to help them operate efficiently by providing financial and utilization information, physician and patient educational programs and disease and medical management programs. Our programs are also designed to help the physicians coordinate care rendered by other providers.

We believe our local and collaborative approach with physicians and other providers gives us a competitive advantage in entering new markets. Our physicians serve on local committees that assist us in implementing preventive care programs, managing costs and improving the overall quality of care delivered to our members, while also simplifying the administrative burdens on our providers. This approach has enabled us to strengthen our provider networks through improved physician recruitment and retention that, in turn, have helped to increase our membership base. The following are among the services we provide to support physicians:

   

Our contracted physicians also benefit from several of the services offered to our members, including the MemberConnections, EPSDT case management and health management programs. For example, the MemberConnections staff facilitates doctor/patient relationships by connecting members with physicians, the EPSDT programs encourage routine checkups for children with their physicians and the health management programs assist physicians in managing their patients with chronic disease.

Where appropriate, our health plans contract with our specialty services organizations to provide services and programs such as behavioral health management, care management software, dental benefits management, home-based primary care services, life and health management, managed vision, pharmacy benefits management, specialty pharmacy and telehealth services. When necessary, we also contract with third-party providers on a negotiated fee arrangement for physical therapy, home healthcare, dental, diagnostic laboratory tests, x-ray examinations, transportation, ambulance services and durable medical equipment.

Quality Management  

Our medical management programs focus on improving quality of care in areas that have the greatest impact on our members. We employ strategies, including health management and complex case management, which are adjusted for implementation in our individual markets by a system of physician committees chaired by local physician leaders. This process promotes physician participation and support, both critical factors in the success of any clinical quality improvement program.

We have implemented specialized information systems to support our medical quality management activities. Information is drawn from our data warehouse, clinical databases and our membership and claims processing system to identify opportunities to improve care and to track the outcomes of the interventions implemented to achieve those improvements. Some examples of these programs include:

We provide reporting on a regular basis using our data warehouse. State and Health Employer Data and Information Set (HEDIS) reporting constitutes the core of the information base that drives our clinical quality performance efforts. This reporting is monitored by Plan Quality Improvement Committees and our corporate medical management and quality improvement teams. 

In an effort to ensure the quality of our provider networks, we verify the credentials and background of our providers using standards that are supported by the National Committee for Quality Assurance (NCQA).

It is our objective to provide access to the highest quality of care for our members. As a validation of that objective, we often pursue accreditation by independent organizations that have been established to promote healthcare quality. The NCQA Health Plan Accreditation and URAC Health Plan Accreditation programs provide unbiased, third party reviews to verify and publicly report results on specific quality care metrics. While we have achieved or are pursuing accreditation for all of our plans, accreditation is only one measure of our ability to provide access to quality care for our members. We currently have NCQA health plan accreditation in 19 of 22 eligible states.

CMS developed the Medicare Advantage Star ratings system to help consumers choose among competing plans, awarding between 1.0 and 5.0 stars to Medicare Advantage plans based on performance in certain measures of quality. For the 2018 Star rating (calculated in 2017 for the quality bonus payment in 2019), our California D-SNP, Oregon HMO, Oregon PPO, and Arizona D-SNP contracts received 4.0 out of 5.0 Stars. The California HMO, Ohio, Texas, and Wisconsin D-SNPs, and Oregon Trillium HMO contracts were measured at 3.5 Stars, and our Arizona HMO and Florida D-SNP contracts received 3.0 Stars. In addition, for the 2018 Star rating, we carry a 3.5 Star parent organization rating. We are currently appealing the 2018 Star rating.

SPECIALTY SERVICES  

Our specialty services are a key component of our healthcare strategy and complement our core Managed Care business. Our provision of specialty services diversifies our revenue stream, enhances the quality of health outcomes for our members and others, and allows Centene to manage costs. Our Envolve brand brings together our extensive portfolio of specialty healthcare solutions. Envolve leverages our collective expertise in pharmacy solutions; health, triage, wellness and disease management; and vision and dental services, to provide integrated and comprehensive healthcare for members. Our specialty services are provided primarily as follows: 

We currently have NCQA accreditation and URAC accreditation for several of our specialty companies.

CORPORATE COMPLIANCE

Our Ethics and Compliance program assists the organization in developing effective internal controls that promote prevention and detection of fraud, waste and abuse and resolution of instances of conduct that do not conform to federal and state law and private payor healthcare program requirements, as well as our own ethics and business policies. Responsibilities also include the ongoing maintenance of our privacy program and oversight of the Health Insurance Portability and Accountability Act (HIPAA) as they pertain to us and our business units from a compliance, business, and technical perspective.

Three standards by which corporate compliance programs in the healthcare industry are measured are the Federal Organizational Sentencing Guidelines, the CMS Chapter Guidance and the Compliance Program Guidance series issued by the Department of Health and Human Services' Office of the Inspector General (OIG). Our program contains each of the seven elements suggested by the Sentencing Guidelines and the OIG guidance. These key components are:

The goal of our program is to build a culture of ethics and compliance, which is assessed periodically to measure the values and engagement of the organization. Our Corporate Compliance intranet site, accessible to all employees, contains our Business Ethics and Conduct Policy (Code of Conduct), Compliance Program description and resources for employees to report concerns or ask questions. If needed, employees have access to the contact information for our Board of Directors' Audit Committee Chairman to report concerns. Our Ethics and Compliance Helpline is a toll-free number and web-based reporting tool operated by a third party independent of the Company and allows employees or other persons to report suspected incidents of misconduct, fraud, waste, abuse or other compliance violations anonymously. Furthermore, the Board of Directors has established a Corporate Compliance committee that, among other things, reviews ethics and compliance reports on a quarterly basis.

COMPETITION  

We operate in a highly competitive environment in an industry subject to ongoing significant changes resulting from the ACA, business consolidations, new strategic alliances, market pressures, and regulatory and legislative reform including but not limited to the federal and state healthcare reform legislation described under the heading "Regulation." In addition, changes to the political environment may drive additional changes to the competitive landscape.

In our business, our principal competitors for customers, members, and providers consist of the following types of organizations :  

We compete with other managed care organizations and specialty companies for state, federal, and commercial contracts. In addition, the impact of the ACA and potential growth in our segment may attract new competitors including technology companies, new joint ventures, financial services firms, consulting firms and other non-traditional competitors. Before granting a contract, state and federal government agencies consider many factors. These factors include quality of care, financial condition, stability and resources and established or scalable infrastructure with a demonstrated ability to deliver services and establish adequate provider networks. Our specialty companies compete with other providers, such as disease management companies, individual health insurance companies, and pharmacy benefits managers for non-governmental contracts.

We also compete to enroll new members and retain existing members. People who wish to enroll in a managed healthcare plan or to change healthcare plans typically choose a plan based on the quality of care and services offered, ease of access to services, a specific provider being part of the network and the availability of supplemental benefits. We believe that the principal competitive features affecting our ability to retain and increase membership include the range and prices of benefit plans offered, size and quality of provider network, quality of service, responsiveness to customer demands, financial stability, comprehensiveness of coverage, diversity of product offerings, market presence and reputation. The relative importance of each of these factors and the identity of our key competitors varies by market and product. We believe that we compete effectively against other healthcare industry participants.

We also compete with other managed care organizations in establishing provider networks. When contracting with various health plans, we believe that providers consider existing and potential member volume, reimbursement rates, medical management programs, speed of reimbursement and administrative service capabilities. See “Risk Factors - Competition may limit our ability to increase penetration of the markets that we serve.”  

The relative importance of each of the aforementioned competitive factors and the identity of our key competitors varies by market, including by geography and by product.

REGULATION

Our operations are comprehensively regulated at local, state, and federal levels. Government regulation of the provision of healthcare products and services is a changing area of law that varies from jurisdiction to jurisdiction. States have implemented National Association of Insurance Commissioners (NAIC) model regulations, requiring governance practices and risk and solvency assessment reporting. States have adopted these or similar measures to enhance regulations relating to corporate governance and internal controls of HMOs and insurance companies. We are required to maintain a risk management framework and file reports with state insurance regulators.

Regulatory agencies generally have substantial discretion to issue regulations and interpret and enforce laws and rules. Changes in the regulatory environment and applicable laws and rules also may occur periodically, including in connection with changes in political party or administration at the state and federal or national levels. For example, the current administration and certain members of Congress have indicated that they may continue to pursue significant amendments to the ACA. Even if the ACA is not amended or repealed, the current administration could propose changes impacting implementation of the ACA. The ultimate content and timing of any legislation enacted under the current administration that would affect the ACA remains uncertain.

The ACA transformed the U.S. healthcare system through a series of complex initiatives. Some of the ACA's most significant provisions include the imposition of significant fees, assessments and taxes, including the non-deductible tax (technically called a "fee") on health insurers based on prior year net premiums written (the "health insurer fee" or "HIF"); the establishment of federally-facilitated and state-based Health Insurance Marketplaces where individuals and small groups may purchase health coverage; the implementation of certain premium stabilization programs designed to apportion risk amongst insurers; and the optional Medicaid Expansion. State and federal regulators have continued to provide additional guidance and specificity to the ACA, and we continue to monitor this new information and evaluate its potential impact on our business. For a further discussion of the implementation of the ACA, as well as the potential repeal of, or changes to, the ACA, see the risk factor below entitled “The implementation of Health Reform Legislation, as well as potential repeal of or changes to Health Reform Legislation, could materially and adversely affect our results of operations, financial position and cash flows.”

Our regulated subsidiaries are licensed to operate as health maintenance organizations (HMOs), preferred provider organizations (PPOs), third party administrators, utilization review organizations, pharmacies, direct care providers and/or insurance companies in their respective states. In each of the jurisdictions in which we operate, we are regulated by the relevant insurance, health and/or human services departments, departments of insurance, boards of pharmacy and other healthcare providers, and departments of health that oversee the activities of managed care organizations and health plans providing or arranging to provide services to enrollees.  

The process for obtaining authorization to operate as a managed care organization, health insurance plan, pharmacy or provider organizations is complex and requires us to demonstrate to the regulators the adequacy of the health plan's organizational structure, financial resources, utilization review, quality assurance programs, proper billing, complaint procedures, and an adequate provider network and procedures for covering emergency medical conditions. For example, under both state managed care organization statutes and insurance laws, our health plan subsidiaries, as well as our applicable specialty companies, must comply with minimum statutory capital and other financial solvency requirements, such as deposit and surplus requirements. Insurance regulations may also require prior state approval of acquisitions of other managed care organization businesses and the payment of dividends, as well as notice for loans or the transfer of funds. Our subsidiaries are also subject to periodic state and federal reporting requirements. In addition, each health plan and individual healthcare provider must meet criteria to secure the approval of state regulatory authorities before implementing certain operational changes, including without limitation changes to existing offerings, the development of new product offerings, certain organizational restructurings and, in some states, the expansion of service areas. 

States have adopted a number of regulations that may affect our business and results of operations. These regulations in certain states include:

Federal law has also implemented other health programs that are partially funded by the federal government, such as the Medicaid program. Our Medicaid programs are regulated and administered by various state regulatory bodies. Federal funding remains critical to the viability of these programs. Federal law permits the federal government to oversee and, in some cases, to enact, regulations and other requirements that must be followed by states with respect to these programs. Medicaid is administered at the federal level by CMS. Comprehensive legislation, specifically Title XVIII of the Social Security Act, governs our Medicare program. In addition, our Medicare contracts are subject to regulation by CMS. CMS has the right to audit Medicare contractors and the healthcare providers and administrative contractors who provide certain services on their behalf to determine the quality of care being rendered and the degree of compliance with CMS contracts and regulations.

We are regulated as an insurance holding company and are subject to the insurance holding company acts of the states in which our insurance company and HMO subsidiaries are domiciled. These acts contain certain reporting requirements as well as restrictions on transactions between an insurer or HMO and its affiliates. These holding company laws and regulations generally require insurance companies and HMOs within an insurance holding company system to register with the insurance department of each state where they are domiciled and to file with those states' insurance departments reports describing capital structure, ownership, financial condition, intercompany transactions and general business operations. In addition, depending on the size and nature of the transaction, there are various notice and reporting requirements that generally apply to transactions between insurance companies and HMOs and their affiliates within an insurance holding company structure. Some insurance holding company laws and regulations require prior regulatory approval or, in certain circumstances, prior notice of certain material intercompany transfers of assets as well as certain transactions between insurance companies, HMOs, their parent holding companies and affiliates. Among other provisions, state insurance and HMO laws may restrict the ability of our regulated subsidiaries to pay dividends.  

Additionally, the holding company acts of the states in which our subsidiaries are domiciled restrict the ability of any person to obtain control of an insurance company or HMO without prior regulatory approval. Under those statutes, without such approval or an exemption, no person may acquire any voting security of an insurance holding company, which controls an insurance company or HMO, or merge with such a holding company, if as a result of such transaction such person would “control” the insurance holding company. “Control” is generally defined as the direct or indirect power to direct or cause the direction of the management and policies of a company and is presumed to exist if a person directly or indirectly owns or controls 10% or more of the voting securities of a company.

PPO regulation also varies by state and covers all or most of the subject area referred to above.

Our pharmacies must be licensed to do business as pharmacies in the states in which they are located. Our pharmacies must also register with the U.S. Drug Enforcement Administration and individual state controlled substance authorities to dispense controlled substances. In many of the states where our pharmacies deliver pharmaceuticals, there are laws and regulations that require out-of-state mail order pharmacies to register with that state’s board of pharmacy or similar regulatory body. These states generally permit the pharmacy to follow the laws of the state in which the mail order pharmacy is located, although some states require that we also comply with certain laws in that state.

Our healthcare providers must be licensed to practice medicine and do business as care providers in the state in which they are located. In addition, they must be in good standing with the applicable medical board, board of nursing or other applicable entity. Furthermore, they cannot be excluded from participation at both the state and federal levels. Our facilities are periodically reviewed by state departments of health and other regulatory agencies to ensure the environment is safe to provide care.

We must also comply with laws and regulations related to the award, administration and performance of U.S. Government contracts. Government contract laws and regulations affect how we do business with our customers and, in some instances, impose added costs on our business. Money laundering is a method of attempting to conceal the origins of money gained through illegal activity and is itself a crime that can result in substantial criminal and civil sanctions including fines and imprisonment. To ensure compliance with anti-money laundering laws and regulations, it is our policy to conduct business only with legitimate customers and counterparties whose funds are derived from legitimate commercial activity. In addition, as a result of our international operations, we are also subject to the U.S. Foreign Corrupt Practices Act (FCPA) and similar worldwide anti-corruption laws, including the U.K. Bribery Act of 2010, which generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. A violation of specific laws and regulations by us and/or our agents could result in, among other things, the imposition of fines and penalties on us, changes to our business practices, the termination of our contracts or debarment from bidding on contracts.

State and Federal Contracts

In addition to being a licensed insurance company or HMO, in order to be a Medicaid managed care organization in each of the states in which we operate, we generally must operate under a contract with the state's Medicaid agency. States generally either use a formal proposal process, reviewing a number of bidders, or award individual contracts to qualified applicants that apply for entry to the program. Under these state Medicaid program contracts, we receive monthly payments based on specified capitation rates determined on an actuarial basis. These rates differ by membership category and by state depending on the specific benefits and policies adopted by each state. In addition, several of our Medicaid contracts require us to maintain Medicare Advantage special needs plans, which are regulated by CMS, for dual eligible individuals within the state. We also contract with states to provide healthcare services to correctional facilities.

We provide Medicare Advantage, Dual Eligible Special Needs Plans (D-SNPs), and Medicare-Medicaid Plans (MMP) which are provided under contracts with CMS and subject to federal regulation regarding the award, administration and performance of such contracts. CMS also has the right to audit our performance to determine our compliance with these contracts, as well as other CMS regulations and the quality of care we provide to Medicare beneficiaries under these contracts. We additionally provide behavioral and other healthcare services to correctional systems under contracts in certain states which are also subject to state regulation.

Our government contracts include government-sponsored managed care and administrative services contracts through the TRICARE program, the Department of Defense Military and Family Life Counseling program, the U.S. Department of Veterans Affairs Patient Centered Community Care program and certain other healthcare-related government contracts.

Our state and federal contracts and the regulatory provisions applicable to us generally set forth the requirements for operating in the Medicaid and Medicare sectors, including provisions relating to:

A health plan or individual health insurance provider's compliance with these requirements is subject to monitoring by state regulators and by CMS. A health plan is also subject to periodic comprehensive quality assurance evaluations by a third-party reviewing organization and generally by the insurance department of the jurisdiction that licenses the health plan. A health plan or individual health insurance provider must also submit reports to various regulatory agencies, including quarterly and annual statutory financial statements and utilization reports.

Our health plans operate through individual state contracts, generally with an initial term of one to five years. The contracts often have renewal or extension terms or are renewable through the state's reprocurement process. The contracts generally are subject to termination for cause, an event of default or lack of funding, among other things.

Marketplace Contracts

We operate in 15 states under federally-facilitated and state-based Marketplace contracts with CMS that expire annually. In 2018, we began operating under Marketplace contracts in Kansas, Missouri and Nevada. We expect to begin operating under a Marketplace contract in New York, pending the closing of the Fidelis Care Transaction.

We operate under a contract with the Arkansas Department of Human Services Division of Medical Services and the Arkansas Insurance Department to participate in the Medicaid expansion model that Arkansas has adopted (referred to as "Arkansas Works"). We also operate under a contract with the New Hampshire Department of Health and Human Services to participate in the Medicaid expansion model that New Hampshire has adopted (referred to as the “Premium Assistance Program”).

Privacy Regulations

We are subject to various international, federal, state and local laws and rules regarding the use, security and disclosure of protected health information, personal information, and other categories of confidential or legally protected data that our businesses handle. Such laws and rules include, without limitation, the Health Insurance Portability and Accountability Act (HIPAA), the Federal Trade Commission Act, the Gramm-Leach-Bliley Financial Modernization Act of 1999 (Gramm-Leach-Bliley Act), state privacy and security laws such as the California Confidentiality of Medical Information Act and the California Online Privacy Protection Act. Privacy and security laws and regulations often change due to new or amended legislation, regulations or administrative interpretation. A variety of state and federal regulators enforce these laws, including but not limited to the U.S. Department of Health and Human Services (HHS), the Federal Trade Commission, state attorneys general and other state regulators.   

HIPAA is designed to improve the portability and continuity of health insurance coverage, simplify the administration of health insurance through standard transactions and ensure the privacy and security of individual health information. Among the requirements of HIPAA are the Administrative Simplification provisions which include: standards for processing health insurance claims and related transactions (Transactions Standards); requirements for protecting the privacy and limiting the use and disclosure of medical records and other personal health information (Privacy Rule); and standards and specifications for safeguarding personal health information which is maintained, stored or transmitted in electronic format (Security Rule). The Health Information Technology for Economic and Clinical Health (HITECH) Act amended certain provisions of HIPAA and enhanced data security obligations for covered entities and their business associates. HITECH also mandated individual notifications in instances of a data breach, provided enhanced penalties for HIPAA violations, and granted enforcement authority to states' Attorneys Generals in addition to the HHS Office for Civil Rights. The HIPAA Omnibus Rule further enhanced the changes under the HITECH Acts and the Genetic Information Nondiscrimination Act of 2008 (GINA) which clarified that genetic information is protected under HIPAA and prohibits most health plans from using or disclosing genetic information for underwriting purposes. This Omnibus rule enhances the privacy protections and strengthens the government's ability to enforce the law. These regulations also establish significant criminal penalties and civil sanctions for non-compliance. The preemption provisions of HIPAA provide that the federal standards will not preempt state laws that are more stringent than the related federal requirements.

The Privacy and Security Rules and HITECH/Omnibus enhancements established requirements to protect the privacy of medical records and safeguard personal health information maintained and used by healthcare providers, health plans, healthcare clearinghouses, and their business associates.

The Security Rule requires healthcare providers, health plans, healthcare clearinghouses, and their business associates to implement administrative, physical and technical safeguards to ensure the privacy and confidentiality of health information electronically stored, maintained or transmitted. The HITECH Act and Omnibus Rule enhanced a federal requirement for notification when the security of protected health information is breached. In addition, there are state laws that have been adopted to provide for, among other things, private rights of action for breaches of data security and mandatory notification to persons whose identifiable information is obtained without authorization.

The requirements of the Transactions Standards apply to certain healthcare related transactions conducted using "electronic media." Since "electronic media" is defined broadly to include "transmissions that are physically moved from one location to another using portable data, magnetic tape, disk or compact disk media," many communications are considered to be electronically transmitted. Under HIPAA, health plans and providers are required to have the capacity to accept and send all covered transactions in a standardized electronic format. Penalties can be imposed for failure to comply with these requirements. The transaction standards were modified on October 1, 2015 with the implementation of the ICD-10 coding system.

In addition, we process and maintain personal card data, particularly in connection with our Marketplace business. As a result, we must maintain compliance with the Payment Card Industry (PCI) Data Security Standard, which is a multifaceted security standard intended to optimize the security of credit, debit and cash card transactions and protect cardholders against misuse of their personal information.

Other Fraud, Waste and Abuse Laws

Investigating and prosecuting healthcare fraud, waste and abuse continues to be a top priority for state and federal law enforcement entities. The focus of these efforts has been directed at Medicare, Medicaid, Health Insurance Marketplace and commercial products. The fraud, waste and abuse laws include the federal False Claims Act, which prohibits the known filing of a false claim or the known use of false statements to obtain payment from the federal government. Many states have false claim act statutes that closely resemble the federal False Claims Act. The laws and regulations relating to fraud, waste and abuse and the requirements applicable to health plans and providers participating in these programs are complex and change regularly. Compliance with these laws may require substantial resources. We are constantly looking for ways to improve our waste, fraud and abuse detection methods. While we have both prospective and retrospective processes to identify abusive patterns and fraudulent billing, we continue to increase our capabilities to proactively detect inappropriate billing prior to payment.
