Skilled nursing facilities, also referred to as rehab hospitals or nursing homes, are for people who require 24-hour nursing services and skilled medical care. SNFs offer short-term rehabilitation stays that may be covered by Medicare, for up to 100 days. In order to have your stay covered by Medicare, you must enter a Medicare-approved SNF within 30 days of a hospital stay that lasted at least three days. Many skilled nursing facilities have a hospital or clinical feel with hospital beds and shared rooms. If your loved one is confined to a bed, or requires extensive nursing services, a skilled nursing facility is the best option.
