Medicare Basics.
Medicare is the federal health insurance program for people age 65 and older, and for certain younger individuals with disabilities. It is administered nationwide by the Centers for Medicare & Medicaid Services (CMS).
Understanding how Medicare works is the first step to choosing the right plan for your health and your budget.
Original Medicare: Part A & Part B
Medicare is made up of two core parts, often called Original Medicare:
Part A
(Hospital Insurance)
Covers inpatient hospital care, skilled nursing, hospice, and some home health services.
Premium is usually $0 if you or your spouse worked and paid Medicare taxes for at least 10 years.
Think of Part A as your “room and board” coverage for hospital stays and facilities.
Part B
(Medical Insurance)
Covers doctor visits, outpatient care, preventative services, durable medical equipment, and some home health care.
Premium is income-based.
Think of Part B as your “doctor and outpatient” coverage, everything outside the hospital walls.
Important: Original Medicare (Part A & B) does not cover everything. You’re responsible for deductibles, coinsurance, and there is no out-of-pocket maximum.
Medicare Options Beyond Parts A & B
Because Original Medicare leaves gaps, most people choose one of these paths to round out their coverage:
Medicare Advantage (Part C): Private plans that bundle Part A & B, usually Part D, and often include extras like dental, vision, hearing, and fitness.
Best for people who want an all-in-one plan with lower upfront costs but are comfortable with provider networks.
Prescription Drug Plans (Part D): Standalone plans that cover medications. Usually paired with Original Medicare or Medigap.
Best for those sticking with Original Medicare + Medigap who need drug coverage.
Medicare Supplement (Medigap): Private policies that help pay deductibles, coinsurance, and gaps left by Original Medicare.
Best for people who want freedom to see any doctor nationwide and predictable costs.
Ancillary Products: Add-ons like dental, vision, or hearing plans.
Best for rounding out coverage that Medicare doesn’t touch.
What Does Medicare Cost?
Part A: $0 premium for most (if you worked 10+ years).
Part B: Standard premium, varies yearly based on income.
Part D: Varies by plan.
Medigap & Medicare Advantage: Premiums vary depending on carrier, plan, and location.
Bottom line: Original Medicare is not free, but with the right combination of options, you can design a plan that fits your health and your budget.
When Can I Sign Up?
Enrollment timing is critical. Missing your window can mean penalties.
Initial Enrollment Period (IEP): 7-month window around your 65th birthday (3 months before, your birthday month, and 3 months after).
Example: If you turn 65 on March 8, you can sign up Dec 1 – June 30.
General Enrollment Period (GEP): Jan 1 – Mar 31 if you missed IEP. Coverage starts July 1.
Annual Enrollment Period (AEP): Oct 15 – Dec 7. Make changes to Medicare Advantage or Part D plans.
Open Enrollment Period (OEP): Jan 1 – Mar 31. Switch Medicare Advantage plans.
Special Enrollment Period (SEP): Triggered by life events like retirement, moving, or losing employer coverage. Each SEP has its own rules.
