Medicare Part A in California

Understand your hospital insurance coverage, costs, and how Part A works for California residents.

Hospital Coverage for California’s Medicare Beneficiaries

Part A is your hospital insurance. When a Californian with Medicare is admitted to a hospital — whether it’s Cedars-Sinai in Los Angeles, Stanford Health Care in Palo Alto, or Mercy Medical Center in Redding — Part A is the coverage that pays for that inpatient stay.

The good news: most Californians pay $0 in monthly premiums for Part A because they (or a spouse) paid Medicare taxes during their working years.

What Part A Pays for in California

Part A is specifically designed for facility-based and intensive care:

  • Inpatient hospital stays: Room, meals, nursing care, medications administered during your stay, and operating room services. California has over 400 Medicare-certified hospitals.
  • Skilled nursing recovery: Up to 100 days in a skilled nursing facility following a qualifying 3-day hospital stay — covering rehab after a hip replacement, stroke recovery, or post-surgical care
  • Hospice care: Comfort care for terminal illness, including pain management, counseling, and respite care for family caregivers. California has one of the nation’s largest hospice networks.
  • Home health services: When your doctor orders part-time skilled nursing or therapy to be delivered in your home

Part A Cost-Sharing in 2026

Part A doesn’t work like typical insurance with a simple deductible. It uses a “benefit period” structure — and understanding it can save you from surprise bills.

SituationYour 2026 CostWhat to Know
Monthly premium (40+ work quarters)$0About 99% of Californians qualify
Monthly premium (30-39 quarters)$311Reduced premium for shorter work history
Monthly premium (under 30 quarters)$565Full premium — consider if buying in makes sense
Hospital deductible$1,736Per benefit period, not per year — you could pay this more than once
Hospital days 1 through 60$0/dayFully covered after your deductible
Hospital days 61 through 90$434/dayCoinsurance kicks in — bills add up fast
Lifetime reserve days (91-150)$868/dayYou get 60 of these total in your lifetime
Skilled nursing days 1-20$0/dayAfter qualifying hospital stay
Skilled nursing days 21-100$217/dayCan reach $17,360 for a full 100-day stay

What Is a Benefit Period?

A benefit period starts when you’re admitted to a hospital and ends when you’ve been out of inpatient care for 60 consecutive days. If you’re hospitalized, go home for two months, and are readmitted, that’s a new benefit period with a new $1,736 deductible. This catches many Californians off guard.

Who Gets Premium-Free Part A?

You qualify for $0-premium Part A in California if any of these apply:

  • You worked and paid Medicare taxes for at least 40 quarters (10 years) — even across multiple jobs
  • Your spouse worked and paid Medicare taxes for 40+ quarters (even if you didn’t work outside the home)
  • You’re under 65 and have received SSDI disability benefits for 24 months
  • You have ALS (Lou Gehrig’s disease) — no waiting period
  • You have End-Stage Renal Disease requiring dialysis or a transplant

Part A and Medi-Cal: A Powerful Combination

For lower-income Californians, Medi-Cal (California’s Medicaid) can pay your Part A deductible and coinsurance — effectively making hospital care free. If you’re dual-eligible for both Medicare and Medi-Cal, you’re protected from nearly all Part A out-of-pocket costs.

Protecting Yourself from Part A Gaps

Extended hospital stays and skilled nursing care can create significant bills under Part A. Two strategies California beneficiaries use:

  • Medigap plans: Plans C, D, F, G, M, and N cover the Part A deductible and/or coinsurance. California’s birthday rule lets you switch Medigap plans annually without health screening.
  • Medicare Advantage: MA plans have annual out-of-pocket maximums that cap your total spending — something Original Medicare with Part A alone does not provide. Compare MA plans in your county →
