Medicare Part A
The federal program that covers hospital stays, skilled nursing facility (SNF) stays after qualifying hospitalizations, hospice, and some home health care for people 65+ (and some younger people with disabilities). Most people pay no premium for Part A because they paid into it via payroll taxes.
What it means in practice
Medicare Part A is one of four parts. Part A: inpatient hospital + post-acute SNF + hospice + limited home health. Part B: outpatient + physicians + DME (durable medical equipment). Part C: Medicare Advantage (the private-plan alternative to A+B). Part D: prescription drugs.
Part A has its own deductible per benefit period ($1,676 in 2026) — not per year. A "benefit period" starts when you're admitted and ends after 60 consecutive days out of a hospital or SNF. Patients hospitalized repeatedly in a single year can owe the deductible multiple times. Past day 60 of a single hospitalization, daily coinsurance kicks in ($419/day for days 61-90, $838/day for days 91-150 from a lifetime reserve, then 100% patient responsibility).
The most-misunderstood Part A coverage is SNF: it covers up to 100 days of skilled nursing care per benefit period, BUT only after a "qualifying hospital stay" of 3+ consecutive inpatient days (observation status does NOT count toward the 3-day requirement — this is the trap that catches many families). Days 1-20 in SNF are fully covered; days 21-100 require $209.50/day coinsurance.
Part A does NOT cover long-term custodial care in a nursing home (that's Medicaid territory once assets are spent down), most outpatient care, dental, vision, hearing aids, or prescription drugs taken at home. Families assume Medicare covers more than it does; the gap is where families end up spending out-of-pocket or transitioning to Medicaid.
When you'll hear it
At hospital admission ("which insurance do you have?"). Part A covers the hospital itself; Part B covers the doctors.

Terms families frequently confuse with medicare part a.
Is medicare part a the same as medicare advantage?
Medicare Advantage (Part C) is a private-insurance alternative that replaces Part A + Part B. Patients with Medicare Advantage technically still have Part A and B but receive their care through the MA plan's rules, network, and cost-sharing instead of original Medicare's.
Is medicare part a the same as medicaid?
Medicare is federal, age- or disability-based, with no income test. Medicaid is joint federal-state, income- and asset-tested. Medicare covers acute medical care; Medicaid covers long-term custodial nursing-home care. Many low-income older adults are "dually eligible" — they have both.
