Original Medicare Part A can cover short-term skilled nursing facility care only when every applicable coverage condition is met. Confirm eligibility with the hospital, the facility, and Medicare or the Medicare Advantage plan before transfer.
How to compare facilities step by step
- Confirm Part A and available benefit days. Verify that the patient has Part A and has covered skilled nursing days remaining in the benefit period.
- Confirm hospital inpatient status. For Original Medicare, verify a qualifying inpatient hospital stay of at least three consecutive days; observation and emergency-room time generally do not count.
- Confirm the transfer timing. The patient generally must enter the skilled nursing facility within 30 days after leaving the hospital.
- Document the skilled need. A clinician must determine that daily skilled nursing or therapy is needed for a covered condition.
- Choose a Medicare-certified facility. Coverage requires care from or under skilled staff in a Medicare-certified skilled nursing facility.
The qualifying inpatient hospital stay is often the first checkpoint
Original Medicare generally requires a medically necessary inpatient hospital stay of at least three consecutive days, not counting the discharge day. Time classified as emergency-room care or outpatient observation generally does not count, even when the patient stays overnight.
Some approved Accountable Care Organizations have a three-day-rule waiver, and Medicare Advantage plans may waive the usual inpatient-stay minimum. Ask which rules apply instead of assuming the exception is available.
The patient must need daily skilled care
A doctor or other qualified clinician must decide that the patient needs daily care that can only be safely and effectively performed by, or under the supervision of, skilled nursing or therapy professionals. The services must relate to a condition treated during the qualifying hospital stay or a condition that began during the covered SNF stay.
Medicare coverage can support care needed to improve or maintain the current condition or prevent or delay deterioration; coverage is not limited to patients who are expected to fully recover.
Eligibility is not the same as guaranteed coverage for every day
The facility must document that skilled services remain reasonable and necessary. Coverage can end before day 100 when skilled care is no longer required, and Medicare generally does not cover custodial long-term care when help with daily activities is the only need.
Frequently asked questions
Does observation status count toward Medicare’s three-day SNF rule?
Generally no. Under Original Medicare, emergency-room and outpatient observation time does not count toward the qualifying three-day inpatient hospital stay.
Does every Medicare Advantage plan require three inpatient days?
Not necessarily. Medicare Advantage plans may waive the three-day minimum, so contact the plan for its current authorization and network rules.
Must a patient be improving for Medicare to cover skilled care?
No. Skilled care may be covered when it is needed to improve or maintain the condition or prevent or delay deterioration, as long as the other coverage requirements are met.
