Understanding Medicare in plain English.
Medicare has several parts, enrollment periods, and coverage paths. Senior Health MN helps you understand what each option does, how the pieces fit together, and what questions to ask before making a decision.
What is Medicare?
Medicare is federal health insurance primarily for people age 65 and older, as well as certain younger people with disabilities or qualifying medical conditions. Most people begin with Part A and Part B, then decide how they want to receive their benefits and whether they need additional coverage.
Hospital Insurance
Part A generally helps cover inpatient hospital care, skilled nursing facility care, hospice care, and certain home health services.
Medical Insurance
Part B generally helps cover doctor visits, outpatient care, preventive services, medical equipment, and other medically necessary services.
Medicare Advantage
Part C is another way to receive Part A and Part B benefits through a private Medicare-approved plan. Many plans include Part D and may offer additional benefits.
Prescription Drug Coverage
Part D helps pay for covered prescription drugs. It may be purchased as a standalone plan or included with many Medicare Advantage plans.
Original Medicare or Medicare Advantage?
Both paths begin with Medicare eligibility, but they differ in how coverage is delivered, how provider access works, and how costs are structured.
Original Medicare
- Includes Part A and Part B
- Use any provider that accepts Medicare
- Add a separate Part D drug plan if needed
- May pair with a Medicare Supplement policy
- No annual out-of-pocket maximum by itself
Medicare Advantage
- Private Medicare-approved plan
- Includes Part A and Part B benefits
- Usually includes Part D drug coverage
- Often uses provider networks and plan rules
- Includes an annual out-of-pocket maximum
Where Medicare Supplement insurance fits.
Medicare Supplement insurance, commonly called Medigap, works with Original Medicare. It can help pay certain deductibles, coinsurance, and copayments that Original Medicare does not fully cover.
Works with Original Medicare
You generally need both Part A and Part B to purchase a Medigap policy.
Separate drug coverage
Modern Medigap policies do not include prescription drug coverage, so a separate Part D plan may be needed.
One person per policy
Each spouse needs an individual Medigap policy if both want this type of coverage.
When should you enroll?
Most people first become eligible around age 65. Enrollment timing matters because delaying coverage without qualifying employer coverage can cause gaps or late-enrollment penalties.
Initial Enrollment Period
A seven-month window that generally begins three months before the month you turn 65 and ends three months afterward.
Special Enrollment Period
May be available after employer-based coverage ends or following certain qualifying events and exceptional circumstances.
Annual Plan Review
Plan premiums, drug lists, provider networks, and benefits can change. Review your coverage and Annual Notice of Change each year.
Questions worth answering first.
- Are your doctors and hospitals available?
- How are your prescriptions covered?
- What premiums and out-of-pocket costs apply?
- Do you travel or live in more than one state?
- Do you have VA or TRICARE benefits?
- Is dental, vision, or hearing important?
- Will you need referrals or prior authorization?
- How might your health needs change next year?
