Families managing a parent’s decline often discover the hard way that the program they counted on does not cover the bill in front of them. Medicare, the health coverage nearly every American over 65 carries, pays for very little long-term nursing-home care. That job falls to Medicaid, a separate program with its own income and asset tests. The distinction rarely registers until a hospital discharge planner raises it during a crisis, and by then the monthly cost of custodial care is already running.
Medicare’s 100-Day Skilled-Care Limit
Medicare’s nursing coverage is narrow by design. After a qualifying inpatient hospital stay, it pays for a stint in a skilled nursing facility — fully for a limited early stretch and partially for the days beyond, up to a hard ceiling of 100 days per benefit period. That coverage exists only while a patient needs skilled care, meaning services that must be delivered or supervised by licensed medical professionals, such as wound care or rehabilitation therapy. Once the skilled need ends, so does the payment.
Most long-term care is not skilled care. It is custodial care — help with bathing, dressing, eating, and moving around — and Medicare does not pay for it, no matter how long it is needed. That gap is the single most misunderstood feature of the program. A resident who no longer needs daily skilled services but still cannot live independently falls outside Medicare’s coverage entirely, even inside the same facility Medicare paid for weeks earlier.
The 100 days also reset only under specific conditions. Coverage is tied to a benefit period that begins with a hospital admission and ends after a stretch without inpatient or skilled care, so a patient who uses the full allotment cannot simply start a new count without another qualifying hospital stay. And the qualifying stay must be a formal inpatient admission — time spent in the hospital under observation status, even overnight, does not count toward the three-day requirement that unlocks skilled-nursing coverage in the first place. Families discover these lines only when a bill or a denial forces the issue.

The Medicaid Spend-Down and Five-Year Look-Back
Medicaid steps in where Medicare stops, but only for those who meet strict financial limits. Applicants must bring countable assets below a state threshold, which usually means spending down savings on care and other allowed expenses until the balance is low enough to qualify. The home and certain other property are generally exempt, but bank accounts, investments, and similar holdings are counted toward the limit.
The spend-down comes with a catch that surprises many households: a look-back period, generally five years, during which the state reviews asset transfers. Money or property given away or sold below market value in that window can trigger a penalty that delays Medicaid coverage. The rule exists to stop applicants from simply handing assets to heirs on the eve of applying, and it makes the timing of any gifts a consequential decision long before care is needed.
Assets are only half of the qualification test. Medicaid also weighs income, and in most states a nursing-home resident who qualifies must contribute nearly all of their monthly income — Social Security, a pension, and similar payments — toward the cost of care, keeping only a small personal-needs allowance and, where it applies, an income allowance for a spouse still at home. Medicaid then pays the balance the facility charges. The program covers the shortfall, but it expects the resident’s own income to go first, which is why qualifying for Medicaid does not mean the care becomes free.
What Custodial Care Costs Families
The stakes are measured in the price of care itself. Skilled nursing facilities routinely charge several thousand dollars a month, and a stretch of custodial care can extend for years, making it one of the largest expenses a retirement can face. Most people entering nursing homes begin by paying out of pocket, drawing down savings until they either exhaust the money or qualify for Medicaid.
That trajectory is why the Medicare-versus-Medicaid distinction is not academic. A household that assumes Medicare will carry a multi-year nursing stay can burn through savings it expected to leave behind, while one that understands the coverage line can plan the spend-down deliberately. The long-term services and supports that Medicaid ultimately funds are extensive, but reaching them requires clearing a financial bar that Medicare enrollees are rarely warned about in advance.
Timing shapes how much a family keeps. Because the look-back reaches back five years and the spend-down itself can take months, households that map out the transition early can direct spending toward exempt assets and legitimate needs rather than watching it vanish into private-pay bills. Those who wait until a hospital discharge forces the question have far fewer options, and the difference between the two paths is measured not in strategy but in the dollars that either stay with the family or do not. The coverage line between the two programs is fixed; what a household does before reaching it is not.
