The annual deductible for all Medicare Part B beneficiaries is $203 in 2021, an increase of $5 from the annual deductible of $198 in 2020.

CMS is committed to empowering beneficiaries with the information they need to make informed decisions about their Medicare coverage options, including providing new tools to help them make those decisions through the eMedicare initiative. In addition to the recently released premiums and cost sharing information for 2021 Medicare Advantage and Part D plans, we are releasing the premiums and cost sharing information for Fee-for-Service Medicare, so beneficiaries understand their options for receiving Medicare benefits. As previously announced, average 2021 premiums for Medicare Advantage plans are expected to decline 34.2 percent from 2017 while plan choices, benefits, and enrollment continue to increase. The Medicare Advantage average monthly premium will be the lowest in fourteen years (since 2007). Premiums and deductibles for Medicare Advantage and Medicare Part D Prescription Drug plans are already finalized and are unaffected by this announcement.

Medicare Part A covers inpatient hospital, skilled nursing facility, and some home health care services. About 99 percent of Medicare beneficiaries do not have a Part A premium since they have at least 40 quarters of Medicare-covered employment.
The Medicare Part A inpatient hospital deductible that beneficiaries will pay when admitted to the hospital will be $1,484 in 2021, an increase of $76 from $1,408 in 2020. The Part A inpatient hospital deductible covers beneficiaries’ share of costs for the first 60 days of Medicare-covered inpatient hospital care in a benefit period. In 2021, beneficiaries must pay a coinsurance amount of $371 per day for the 61st through 90th day of a hospitalization ($352 in 2020) in a benefit period and $742 per day for lifetime reserve days ($704 in 2020). For beneficiaries in skilled nursing facilities, the daily coinsurance for days 21 through 100 of extended care services in a benefit period will be $185.50 in 2021 ($176.00 in 2020).
