A Medicare fact sheet updated for 2026 draws a sharp line inside skilled nursing facility coverage: the first 20 days of a covered stay cost a beneficiary nothing, and the 21st day begins a $217-a-day bill that continues through day 100. After that, Original Medicare stops paying its share entirely. The Centers for Medicare & Medicaid Services confirmed these figures for calendar year 2026, up from $209.50 a day in 2025, in the same publication it reissues every December ahead of the coming year’s premiums and cost-sharing amounts.
A Free Stretch, Then A Bill That Compounds Fast
Under the 2026 cost-sharing schedule published in CMS Product No. 11579, a Medicare beneficiary admitted to a skilled nursing facility owes nothing for the first 20 days of care in a benefit period, provided the Part A hospital deductible was already satisfied during that same benefit period. Medicare’s own cost fact sheet shows the free stretch ends abruptly on day 21, when the daily coinsurance jumps from $0 to $217 and holds there through day 100. Across the full 80-day window in which that coinsurance applies, the charge totals $17,360, a sum few retirees living on a fixed Social Security check have budgeted to cover out of pocket.
The 2026 rate did not appear out of nowhere. CMS’s November announcement of that year’s Part A and Part B figures shows the skilled nursing coinsurance climbing from $209.50 in 2025 to $217.00 in 2026, the same update that pushed the Part A hospital deductible to $1,736 and the daily coinsurance for hospital days 61 through 90 to $434. All three numbers move together because they are tied to the same formula for Medicare cost growth, so the fact sheet CMS released alongside those figures documents a real, year-over-year increase in what a long skilled nursing stay costs a beneficiary, not a rounding adjustment.
None of the cost sharing applies unless the stay first qualifies for coverage at all. Medicare’s coverage page for skilled nursing facility care states that a beneficiary needs a prior, medically necessary inpatient hospital stay of at least three consecutive days, not counting the day of discharge, before Medicare will pay anything toward a skilled nursing facility admission. Time spent under hospital observation, even overnight, does not count toward that three-day requirement, a distinction that has left patients believing a hospital admission automatically unlocked nursing home coverage when, under Medicare’s own rule, it had not.

Why The Cost Clock Resets Instead Of Running On A Calendar Year
The $0-then-$217 structure resets with each new benefit period rather than running on a calendar year, a mechanic that surprises beneficiaries who expect Medicare cost sharing to behave like an ordinary annual insurance deductible. A benefit period begins the day a person is admitted as a hospital inpatient or enters a skilled nursing facility and stays open until Medicare considers the episode closed. A retiree hospitalized twice in the same year for two unrelated conditions can face the Part A deductible, the day-1-through-20 free stretch, and the $217-a-day schedule more than once within twelve months, each time treated as its own benefit period rather than credited against an annual total.
For beneficiaries who anticipate a stay long enough to reach the $217-a-day stretch, the cost-sharing schedule offers no advance-notice mechanism beyond what a facility’s own billing office provides. Medicare’s fact sheet lists the dollar amounts but does not require a facility to warn a beneficiary in advance that day 21 is approaching. A beneficiary or family member tracking the calendar independently, and asking a facility’s billing department for a running day count, is often the only way to anticipate the shift from a $0 daily rate to $217 before the first bill reflecting it arrives.
That reset mechanic means the $217 daily rate is not necessarily a single hurdle a household clears once and moves past. A person recovering from a hip fracture who is hospitalized again later in the year for a cardiac event can face two separate skilled nursing stretches, each with its own 20 free days and its own post-day-20 bill. Medicare Advantage plans add another layer of variation: many structure skilled nursing cost sharing differently than Original Medicare, some charging a per-day copayment starting well before day 21, so a beneficiary comparing coverage during open enrollment is weighing two genuinely different exposure profiles for what could be the identical hospital stay and the identical nursing facility.
No Ceiling Once The Bill Passes Day 100
The schedule contains no stopping point once a stay runs past day 100. CMS’s fact sheet states plainly that a beneficiary pays all costs for skilled nursing facility care beyond the hundredth day of a benefit period, with no catastrophic cap built into Original Medicare and no automatic Medicaid backstop unless a beneficiary separately qualifies for that program on income and asset grounds. Because the skilled nursing benefit was designed as a short-term, rehabilitation-focused piece of Medicare rather than a long-term care program, a stay that runs past 100 days shifts an entire daily rate, often several hundred dollars in a private facility, onto the beneficiary or a supplemental policy.
A Medigap policy can blunt part of that exposure before day 100 arrives, though not after it. Medicare’s own description of what a Medigap policy covers lists coinsurance among the out-of-pocket costs a supplemental plan is built to absorb, which for a Medigap policyholder can mean the $217-a-day skilled nursing coinsurance is paid by the supplemental insurer rather than out of the beneficiary’s own funds during days 21 through 100. That protection has a hard limit: Medigap does not extend Medicare’s own 100-day skilled nursing ceiling, and a stay Medicare no longer covers at all is a stay no Medigap policy will pay for either, regardless of which lettered plan a beneficiary holds.
The distinction matters most to families making a placement decision under pressure, often within days of a hospital discharge and without time to compare a facility’s daily rate against what Medicare and any supplemental coverage will actually pay. A stay projected to run past the 100-day mark follows a cost trajectory that starts at zero, rises to $217 a day, and then removes Medicare from the bill altogether, a sequence CMS spells out in its own fact sheet but one a family standing in a hospital discharge office rarely hears explained before the clock on day one starts running.
