What Is Medicare?

by Staff

Medicare, a government-run healthcare program in the United States, provides health insurance for eligible individuals. It was established in 1965 under President Lyndon B. Johnson as Part of his Great Society initiatives.


A Comprehensive Overview of Medicare

Medicare is a federal health insurance program primarily designed for individuals aged 65 and older. Still, it also provides coverage for younger people with specific disabilities and those with end-stage renal disease. Established in 1965, Medicare aims to alleviate the financial burden of medical expenses by providing accessible and affordable healthcare coverage. It consists of several parts, each addressing different aspects of healthcare, from hospital stays to prescription medications.


  1. Part A: Hospital Insurance

It covers inpatient hospital stays, skilled nursing care, hospice care, and limited home healthcare services. Individuals who have paid Medicare taxes for a certain period or are married to someone who has can generally receive Part A coverage without a premium.


  1. Part B: Medical Insurance

This section covers outpatient services, doctor visits, preventive care, and medically necessary supplies. It requires a monthly premium, and the cost depends on the recipient’s income. Most beneficiaries enroll in Part B to have comprehensive coverage for their healthcare needs.


  1. Part C: Medicare Advantage

It is an alternative to Original Medicare (Part A and B). Private insurance companies approved by Medicare offer Part C plans, often including additional benefits such as prescription drug coverage and vision, dental, and hearing services.


These plans may have different costs and rules compared to Original Medicare. Medicare Advantage plans may have provider networks, which means individuals may need to use specific doctors and hospitals within the network.


  1. Part D: Prescription Drug Coverage

This Part allows beneficiaries to purchase insurance plans that cover prescription medication costs. Private insurance companies offer part D plans and can vary in terms of premiums, drug formulae, and out-of-pocket costs.


Medicare is funded through payroll taxes, premiums paid by beneficiaries, and general government revenue. Most people do not have to pay a premium for Part A if they or their spouse have paid Medicare taxes while working. Part B and Part D require monthly premiums, and the cost varies based on income and other factors. Medicare Advantage plans may have additional bonuses in addition to the Part B premium.


Qualifying for Medicare

Qualifying for Medicare is primarily based on age and specific eligibility criteria. Medicare automatically enrolls most individuals aged 65 and older eligible for Social Security benefits or the Railroad Retirement Board. However, there are additional circumstances under which individuals under 65 can qualify. For instance, those who have received Social Security disability benefits for at least 24 months can become eligible for Medicare.


Additionally, individuals with end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS) can qualify for Medicare, regardless of age or the duration of benefits received. These provisions ensure that a broader range of individuals can access Medicare’s necessary healthcare coverage.


Coverage Gaps and Out-Pocket Costs

There are gaps in coverage, and beneficiaries are responsible for paying certain costs such as deductibles, copayments, and coinsurance. Individuals need to understand that Medicare does not cover everything. Individuals can purchase Medigap plans offered by private insurance companies to supplement Medicare coverage.


Some services, such as long-term care, cosmetic surgery, and most dental care, are generally not covered by Medicare. Medigap policies are standardized and labelled with letters (A, B, C, D, F, G, K, L, M, and N), each providing a different level of coverage.


Comprehension and Open Enrollment Periods


Medicare holds annual open enrollment periods to ensure beneficiaries can actively review and adjust their coverage as needed. These periods, typically from October 15 to December 7 each year, enable individuals to change their Medicare plans. It includes switching from Original Medicare to Medicare Advantage, changing prescription drug coverage (Part D) plans, or exploring different Medicare Advantage options. Beneficiaries can reassess their healthcare needs and adjust their coverage by taking advantage of these open enrollment periods to ensure it aligns with their evolving requirements.

Role of Medicare

Medicare plays a crucial role in the healthcare system, providing accessible and affordable coverage for millions of older adults and individuals with disabilities. It offers a safety net, ensuring that individuals have access to necessary medical services and treatments, regardless of their financial situation.


Medicare also allows beneficiaries to maintain continuity of care by providing coverage for healthcare services across different settings and promoting healthier lifestyles among beneficiaries.



Medicare, a government program that provides health insurance to eligible individuals, primarily those aged 65 and older, consists of several parts, including hospital insurance (Part A), medical insurance (Part B), Medicare Advantage (Part C), and prescription drug coverage (Part D).


While Medicare covers many healthcare expenses, there are gaps in coverage, and beneficiaries are responsible for certain costs. Understanding Medicare and its components empowers individuals to make informed choices and access the necessary healthcare services.
