Navigating Medicare's Skilled Nursing Facility Coverage Limits

Medicare's coverage for skilled nursing facilities (SNFs) terminates after 100 days, leading to substantial out-of-pocket expenses for individuals. When these benefits end, families may face monthly costs nearing $9,000 for a semi-private room and $10,000 for a private room, according to recent industry data. This financial challenge underscores the importance of understanding Medicare's coverage limits and exploring supplemental insurance options.

Initially, Medicare Part A offers full coverage for SNF costs during days 1 through 20. However, from days 21 to 100, patients must pay a daily coinsurance, set to increase to $217.00 in 2026. After the 100-day limit, patients must finance SNF costs through personal funds, long-term care insurance, or Medicaid, requiring a qualifying spend-down. Although Medigap plans such as Plan G and Plan N cover the SNF coinsurance, they do not extend Medicare's coverage beyond the 100-day limit.

To qualify for Medicare's SNF coverage, a patient must have a three-day inpatient hospital stay. Stays designated as "observation" do not meet this requirement, potentially leading to denied SNF coverage and unexpected expenses. Patients and families should confirm whether a hospital stay is classified as inpatient or observation and request reclassification if necessary. Hospitals are obliged to provide a Medicare Outpatient Observation Notice (MOON) to inform patients of their status, helping them navigate these regulatory compliance requirements effectively.
