Skilled nursing facility coverage: the level-of-care test
Checked against the current rules on September 22, 2026.
A skilled nursing facility stay is covered when the patient needs daily skilled nursing or therapy that, practically speaking, can only be provided on an inpatient basis — a specific two-part test, not a general judgment call.

Coverage requires the patient need skilled nursing or skilled rehabilitation services on a daily basis, and that daily skilled care realistically can only be provided in a SNF, considering efficiency.Skilled Nursing Facility Level of Care - General
"Skilled services" are specifically defined — services that, by their nature, require the skills of a licensed nurse or therapist to be given safely and effectively, not simply because a nurse happens to be the one giving them.Skilled Services Defined
Traditional Medicare normally requires a prior 3-day inpatient hospital stay before SNF coverage starts. Many Medicare Advantage plans have their own CMS-approved waiver of this requirement — check your specific plan's own rules rather than assuming the 3-day rule applies the same way it does under Traditional Medicare.
As with home health, a lack of potential for improvement can't, by itself, justify denying skilled care that's needed to maintain the patient's condition or slow decline.CMS — Jimmo v. Sebelius Settlement Agreement (D. Vt., approved Jan. 24, 2013)
What this means for your appeal
"Custodial care" is the phrase to watch for in a denial — it means help with daily activities that doesn't require a nurse's or therapist's training. If the actual services being provided are genuinely skilled (wound care, injections, therapy requiring a licensed provider), a "custodial" label is worth directly challenging with specifics.
"Efficiency" — whether skilled care realistically can only be given in a SNF — is its own separate question from whether skilled care is needed at all. A denial should address both; if it only argues the patient doesn't need skilled care, it hasn't actually addressed the efficiency question at all.
Documentation that specifically names the skilled tasks being performed daily (not just "nursing care" generally) and why they can't be safely done at home is usually what turns a borderline SNF appeal into a winning one.
Whether Traditional Medicare's own 3-day-stay requirement applies to your specific case is worth confirming directly with the plan, in writing — a denial based on a missing 3-day stay is invalid if your plan has actually waived that requirement.
