Medicare is federal health insurance primarily for people age 65 or older and for certain younger people with disabilities or qualifying conditions. Part A generally covers inpatient hospital care, Part B covers many outpatient and physician services, Part C is Medicare Advantage offered by private Medicare-approved plans, and Part D covers prescription drugs. Coverage, costs, and eligibility rules vary, so review official Medicare information and the documents for any plan you consider.

Yes. Medicare is a federal health-insurance program. It differs from most employer or individual coverage, and beneficiaries may need to make separate choices about drug coverage, supplemental coverage, or a Medicare Advantage plan.

No. Medicare is a federal health-insurance program based mainly on age or qualifying disability. Medicaid is a joint federal-state program based largely on income and other eligibility rules. Some people qualify for both programs.

Original Medicare includes Part A and Part B and generally allows care from providers that accept Medicare. Medicare Advantage plans are offered by private Medicare-approved companies, provide Part A and Part B benefits, and may include networks, plan rules, prescription coverage, and additional benefits. Details differ by plan and service area.

Original Medicare usually does not cover most outpatient prescription drugs. Beneficiaries may obtain drug coverage through a standalone Part D plan or through a Medicare Advantage plan that includes prescription coverage. Formularies, pharmacies, and costs vary by plan.

Eligibility commonly begins at age 65. Some younger people qualify because of disability, End-Stage Renal Disease, or ALS. Medicare.gov and Social Security provide official, situation-specific eligibility information.

Enrollment timing depends on your circumstances. Common opportunities include an Initial Enrollment Period around age 65, the annual Medicare Open Enrollment Period, and certain Special Enrollment Periods triggered by qualifying events. Missing an enrollment window can affect coverage or costs.

A late-enrollment penalty may apply to Part B or Part D when a person delays enrollment without qualifying coverage or another exception. The amount and duration depend on the program and individual circumstances. Confirm your dates with Medicare or Social Security.

Original Medicare does not cover most routine dental care, routine vision exams for eyeglasses, or hearing aids. Some Medicare Advantage plans offer additional dental, vision, or hearing benefits. Availability, limits, provider networks, and costs vary by plan.

Medicare covers many preventive services, screenings, vaccines, and wellness visits when eligibility and provider requirements are met. Cost sharing and frequency rules can vary by service.

You may still be eligible for Medicare, although Part A premiums and eligibility can depend on your work history or a spouse's work history. Social Security can determine eligibility and premium responsibility for your situation.

Some Medicare Advantage plans may offer SSBCI to qualifying chronically ill enrollees. Benefits and eligibility are plan-specific, are not guaranteed, and may depend on a qualifying condition and other criteria. Review the plan's evidence of coverage for details.
