Medicare Health Plans

What Is Medicare?

Medicare is a federally sponsored health insurance program in the United States designed primarily for individuals aged 65 and older, as well as certain younger individuals with qualifying disabilities or serious medical conditions. It was established in 1965 under the Social Security Act and officially began providing coverage in 1966.

One of the key features of Medicare is that eligibility is not based on income or medical history. This makes it different from many private insurance plans. Instead, eligibility is based mainly on age, disability status, or specific medical diagnoses. Medicare provides access to essential healthcare services, helping millions of Americans manage medical costs during retirement.

Medicare is divided into four main parts—Part A, Part B, Part C, and Part D. Each part covers different types of healthcare services, and understanding how they work together is essential for making informed decisions about coverage.

Medicare Part	Coverage Type	Provider
Part A	Hospital & inpatient care	Federal government
Part B	Outpatient & medical services	Federal government
Part C	All-in-one plans (A + B, often D)	Private insurance companies
Part D	Prescription drug coverage	Private insurance companies

When Do I Qualify For Medicare?

Most individuals qualify for Medicare when they turn 65 years old. However, eligibility can begin earlier under specific circumstances. Understanding when you qualify is important to avoid penalties and gaps in coverage.

Age 65 or older: The most common eligibility requirement
Under 65 with disabilities: After receiving Social Security Disability Insurance (SSDI) for 24 months
End-Stage Renal Disease (ESRD): Permanent kidney failure requiring dialysis or transplant
ALS (Lou Gehrig’s Disease): Immediate Medicare eligibility upon SSDI approval

Your Initial Enrollment Period (IEP) lasts for seven months: three months before your 65th birthday, your birth month, and three months after. Enrolling during this window helps you avoid late penalties.

Enrollment Period	Timeframe	Notes
Initial Enrollment	7 months around age 65	Best time to enroll
General Enrollment	Jan 1 – Mar 31	May include penalties
Annual Enrollment	Oct 15 – Dec 7	Change plans

The Four Parts of Medicare

Medicare Part A is commonly known as hospital insurance. It primarily covers inpatient care and related services rather than all healthcare expenses associated with hospitalization.

Skilled nursing facility care
Semi-private hospital rooms
Meals during inpatient stays
Facility-administered medications and supplies
Home health services (when eligible)
Hospice care for terminal illness

Most beneficiaries do not pay a monthly premium for Part A if they have at least 40 quarters of Medicare-covered employment. Otherwise, a premium may apply.

See how premiums, deductibles, and benefits compare on our Medicare cost and coverage page.

Medicare Part B focuses on outpatient care and preventive services, which are essential for maintaining long-term health and detecting issues early.

Doctor visits and specialist care
Outpatient surgeries
Preventive services (screenings, vaccines)
Durable medical equipment
Emergency room visits
Mental health services
Ambulance transportation

Part B requires a monthly premium and generally includes a deductible and 20% coinsurance for most services. Because of these out-of-pocket costs, many individuals seek additional coverage.

Medicare Part C, also known as Medicare Advantage, is an alternative to Original Medicare. These plans are offered by private insurers and combine Part A and Part B coverage, often including Part D as well.

All-in-one bundled coverage
May include dental, vision, and hearing benefits
Often includes wellness and fitness programs
Network-based plans (HMO or PPO)

Medicare Part D provides prescription drug coverage through private insurance companies. Coverage varies depending on the plan selected.

Multiple plan options with different formularies
Four coverage phases throughout the year
Copays and coinsurance vary by medication
Plans can change annually

Feature	Original Medicare (A & B)	Medicare Advantage (Part C)
Provider Choice	Any provider accepting Medicare	Network-based
Extra Benefits	Limited	Often included
Prescription Drugs	Separate Part D needed	Usually included
Costs	Standardized	Varies by plan

Frequently Asked Questions About Medicare Health Plans

Medicare health plans generally include Original Medicare (Part A and Part B), Medicare Advantage plans (Part C), Medicare Supplement plans (Medigap), and prescription drug plans (Part D).

Each option offers different coverage levels, provider access, and out-of-pocket costs. Comparing plan benefits can help you choose coverage that fits your healthcare and financial needs.

Original Medicare is provided directly by the federal government and includes hospital and medical coverage through Parts A and B.

Medicare Advantage plans are offered by private insurance companies and often include additional benefits such as dental, vision, hearing, fitness programs, and prescription drug coverage.

Original Medicare does not usually include routine prescription drug coverage. Beneficiaries typically enroll in a standalone Medicare Part D plan or choose a Medicare Advantage plan with drug coverage included.

Drug formularies, pharmacy networks, and medication tiers can vary between plans, so reviewing coverage details before enrolling is important.

Medicare costs vary depending on the plan you choose, your income, deductibles, copays, and whether you add supplemental coverage.

Some Medicare Advantage plans may have low or $0 monthly premiums, while Medigap plans may have higher premiums but lower out-of-pocket medical costs.

Yes. Medicare beneficiaries can typically change plans during the Annual Enrollment Period from October 15 through December 7 each year.

Certain life events may also qualify you for a Special Enrollment Period, allowing you to switch plans outside the standard enrollment window.

Many Medicare Advantage plans include additional benefits not covered by Original Medicare, such as dental, vision, hearing, and wellness programs.

Coverage details and provider networks vary by plan, so reviewing benefits carefully can help ensure the plan matches your healthcare needs.

Medicare Supplement insurance, also called Medigap, helps cover certain out-of-pocket costs that Original Medicare does not fully pay.

Depending on the plan selected, Medigap policies may help with deductibles, coinsurance, and copayments while allowing flexibility to see providers that accept Medicare nationwide.

Most people first become eligible for Medicare around their 65th birthday during their Initial Enrollment Period.

Enrolling on time may help avoid late enrollment penalties and gaps in healthcare coverage. Some individuals may also qualify earlier because of certain disabilities or medical conditions.
