What You'll Learn
Medicare: the largest health program in the US
Medicare is the largest health program in the US. It is a federal health insurance program for the elderly and disabled, with Part A covering hospital care and Part B covering medical services. The program was established in 1965 by Title XVIII of the Social Security Act, and has since undergone expansions to include coverage for services such as annual mammograms, Pap smears, cancer screenings, diabetes management, and osteoporosis diagnosis.
The Centers for Medicare and Medicaid Services (CMS) manage Medicare, and it faces a multitude of challenges and decisions daily regarding payment systems, policy and legislative issues, benefits, coverage, operations, and quality. The program is supported by a team of consultants, including former CMS officials, plan executives, payment system and coding experts, and policy analysts, who provide end-to-end solutions to assist organizations in navigating the complexities of Medicare.
Medicare's reach extends across the country, impacting a significant number of Americans. Its scope and influence are evident through its association with other prominent entities in the healthcare industry. For instance, Kaiser Permanente, which offers insurance in only eight states and Washington, DC, is the largest health insurance company by enrollment, with nearly 9 million members. However, Kaiser Permanente is also part of the Blue Cross Blue Shield Association, which covers all 50 states and includes about 90% of doctors and hospitals in its provider network.
The impact of Medicare is further highlighted by the involvement of Health Management Associates (HMA), which provides a comprehensive suite of Medicare policy and operational services. HMA's expertise lies in areas such as healthcare reform, Medicare payment systems, and reimbursement policies. Their acquisition of The Moran Company expanded their capabilities in analyzing Medicare provider payment systems and developing data-driven strategies for their clients.
In conclusion, Medicare's status as the largest health program in the US is underscored by its extensive coverage, complex operational requirements, and the involvement of major healthcare entities and consulting firms. Its evolution since its inception demonstrates the program's adaptability to meet the changing needs of the American population.

Medicaid: specific benefits for children
In the context of the largest medical insurance program, Medicaid, a public health insurance program, provides specific benefits for children. The Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) program, established in 1967, offers comprehensive healthcare services for children, including periodic evaluations of their health, developmental history, and vision, hearing, and dental screenings. Medicaid ensures that children have access to essential healthcare services without financial barriers, as premiums, copayments, and deductibles are generally not allowed for services provided to minors.
Medicaid plays a crucial role in ensuring that children from low-income families have access to healthcare. The State Children's Health Insurance Program (SCHIP), created through the Balanced Budget Act of 1997, provided funds for states to offer coverage to children in families with incomes up to 200% of the federal poverty level (FPL) who did not qualify for Medicaid. This expansion represented a significant step forward in providing health insurance coverage for children, with 4.6 million children enrolled in SCHIP by 2001.
SCHIP offers states flexibility in designing their programs. They can choose to establish a separate child health program, expand Medicaid coverage, or implement a combination of both approaches. This flexibility allows states to tailor their programs to meet the specific needs of their uninsured children.
In addition to SCHIP, some states have further expanded coverage to include uninsured parents of children enrolled in Medicaid or SCHIP. For example, in 2001, Minnesota, New Jersey, Rhode Island, and Wisconsin received approval to enrol parents in SCHIP, demonstrating a growing recognition of the importance of ensuring that families have access to affordable healthcare.
While Medicaid is a significant program for children's healthcare, it is not the only player in the market. Private insurance companies, such as Kaiser Permanente, Anthem, and Centene, also offer health insurance plans with varying levels of coverage. These companies cater to individuals, families, and employers seeking healthcare options for their employees. However, Medicaid's specific benefits for children, as outlined by the EPSDT program, remain a vital safety net for millions of children across the country.

Kaiser Permanente: largest by enrollment
Kaiser Permanente is the largest health insurance company in the United States by enrolment, with nearly 9 million members with individual or group health insurance plans. The company's focus is on low-cost HMO plans that require the use of one of Kaiser's medical centres for healthcare. Kaiser Permanente's quality of care is highly rated, attributed to its focus on preventive care, salaried physicians, and efforts to reduce hospital stays. The company has over 300,000 employees, including more than 98,000 physicians and nurses, and operates 40 hospitals and over 614 medical offices.
Kaiser Permanente's history dates back to the 1930s when a medical group was established to serve workers and their families during the construction of the Grand Coulee Dam in northeastern Washington. During World War II, these physicians served workers and their families at the Kaiser Shipyards in Portland, Oregon, and Vancouver, Washington. With the shipyards' closing in 1945, enrollment was opened to the community. Today, Kaiser Permanente is headquartered in Oakland, California, and serves 12.6 million members, including 12.5 million members and more than 235,000 employees and physicians.
Kaiser Permanente's Labor Management Partnership, the largest of its kind in the United States, involves front-line staff in decision-making to keep care affordable while improving service and quality. The company also pioneered the use of electronic medical records, deploying a system across all eight regions at a cost of more than $6 billion. By 2010, this system served more than 8.6 million members, implemented at a cost exceeding half a million dollars per physician.
Kaiser Permanente's commitment to improving healthcare extends beyond its members to the communities it serves. The company believes that expert care should be equally available to all and continuously works to advance medicine and drive innovative care. In 2002, Kaiser Permanente abandoned its attempt to build its own clinical information system with IBM, instead opting for a "buy, not build" approach and selecting Epic Systems as the primary vendor for its new system, KP HealthConnect.
It is worth noting that while Kaiser Permanente is the largest by enrolment, other companies may rank as the largest health insurance providers when considering other factors, such as revenue or membership in specific states. For example, UnitedHealth is the largest insurer in terms of premium writing, with approximately $248 billion in premiums written in 2023. Additionally, Blue Cross Blue Shield is the largest health insurance company in most states by membership, including affiliates like Elevance (Anthem), Highmark, and CareFirst. Anthem, part of Elevance Health, is the second-largest provider by revenue and has over 5 million health insurance members.
