Which of the following is required for Medicare SNF coverage?

Medicare coverage for skilled nursing facility (SNF) services requires that a beneficiary has a prior inpatient hospital stay of at least three consecutive days. This stipulation is in place to ensure that a patient's care needs have been assessed while they were hospitalized, deeming them appropriate for the level of skilled care provided in an SNF. The three-day inpatient stay establishes the medical necessity for SNF services and is a critical factor in determining eligibility for Medicare to cover these expenses.

Being a resident of a nursing home is not a prerequisite for coverage, as Medicare SNF benefits are specifically tied to the need for post-hospitalization rehabilitation or skilled care rather than residency status. The requirement for a five-day stay is inaccurate, as it is the three-day stay that meets Medicare's criteria. Furthermore, while being enrolled in a Medicaid program may provide additional benefits or support, it is not a requirement for Medicare SNF coverage, as the two programs operate under different eligibility and coverage rules.
