How much of long-term nursing care is covered by Medicare after the first 100 days?

Medicare provides specific coverage for skilled nursing facility care, but this coverage is limited in duration. After the first 100 days in a skilled nursing facility, Medicare does not cover any further costs for long-term nursing care. This 100-day period begins after a qualifying hospital stay of at least three days, during which Medicare covers the full cost of care in a skilled nursing facility for the first 20 days. From days 21 to 100, there are daily coinsurance amounts that the patient is responsible for. However, once this 100-day window closes, any remaining long-term nursing care costs fall entirely on the patient, with no further assistance from Medicare.

This understanding highlights why the assertion that Medicare provides no coverage after the first 100 days is correct. The other options incorrectly suggest different scenarios regarding the extent and duration of Medicare's coverage, thus failing to reflect the actual policy as defined by Medicare.
