Glossary of Medicare Terms

Beneficiary — A person who has Medicare coverage.

Coinsurance — The percentage of costs you pay for a covered service after you’ve met your deductible. Example: Medicare pays 80%, you pay 20%.

Copayment (Copay) — A fixed dollar amount you pay for a covered service. Example: $20 for a doctor visit.

Creditable Coverage — Health coverage (such as employer insurance) that is considered at least as good as Medicare’s coverage. Having creditable coverage protects you from late enrollment penalties.

Deductible — The amount you pay out-of-pocket before your insurance begins to pay. Medicare Part A and Part B each have their own deductible.

Donut Hole (Coverage Gap) — A stage in Part D drug coverage where you previously paid more for prescriptions. Now capped at $2,000/year out-of-pocket thanks to the Inflation Reduction Act.

Dual Eligible — Someone who qualifies for both Medicare and Medicaid.

Extra Help (Low-Income Subsidy / LIS) — A Medicare program that helps people with limited income and resources pay for Part D prescription drug costs.

Formulary — A list of prescription drugs covered by a Part D or Medicare Advantage plan. Drugs are organized into tiers, with lower tiers costing less.

Guaranteed Issue Rights — Rights that protect you from being denied Medigap coverage or charged more due to health conditions. Available during your Medigap Open Enrollment Period and in certain other situations.

HMO (Health Maintenance Organization) — A type of Medicare Advantage plan that generally requires you to use in-network providers and get referrals to see specialists.

Initial Enrollment Period (IEP) — The 7-month window around your 65th birthday when you can first sign up for Medicare.

Medicaid — A joint federal and state program that helps people with limited income and resources pay for healthcare. Different from Medicare.

Medicare Advantage (Part C) — An alternative to Original Medicare offered by private companies. Includes Part A and Part B benefits, and usually Part D.

Medicare Supplement (Medigap) — Private insurance that helps pay for costs Original Medicare doesn’t cover, like coinsurance, copayments, and deductibles.

Network — The group of doctors, hospitals, and other providers that have agreed to work with an insurance plan. Using in-network providers typically costs less.

Original Medicare — The traditional Medicare program (Part A + Part B) administered directly by the federal government.
