Understanding Medicare Parts A, B, C, and D
A current, plain-language orientation to Medicare’s major coverage components and selected 2026 cost figures.
Part A: Hospital insurance
Part A generally covers inpatient hospital care, skilled nursing facility care under qualifying conditions, hospice, inpatient rehabilitation, and certain home health services. In 2026, the inpatient hospital deductible is $1,736 per benefit period.
Part B: Medical insurance
Part B generally covers physicians’ services, outpatient hospital services, durable medical equipment, certain home health services, and other covered medical services. The 2026 standard monthly premium is $202.90 and the annual deductible is $283. Higher-income enrollees may pay an income-related adjustment.
Part C: Medicare Advantage
Medicare Advantage plans are offered by Medicare-approved private companies as an alternative way to receive Part A and Part B benefits. Plans may include Part D coverage and supplemental benefits, but networks, cost sharing, prior authorization, and plan rules vary.
Part D: Prescription-drug coverage
Part D is available through standalone prescription drug plans and many Medicare Advantage plans. Premiums, formularies, pharmacies, and cost sharing vary. In 2026, the annual out-of-pocket threshold for covered Part D drugs is $2,100.
Why annual review matters
Medicare premiums, deductibles, thresholds, plan offerings, and formularies can change annually. Communications should identify the applicable year and link to current Medicare or CMS material.
