If you ever need short-term rehabilitation or skilled nursing care after a hospital stay, one Medicare rule could make all the difference in whether your care is covered — the 3-midnight rule. This often-overlooked guideline determines when Medicare Part A will pay for a Skilled Nursing Facility (SNF) stay, and misunderstanding it can lead to costly surprises.

As a trusted, independent Medicare brokerage, Emerald Medicare helps clients across the country navigate these details with confidence. Here’s what you need to know about how the 3-midnight rule works — and how to protect yourself from unexpected expenses.

What is the 3-Midnight rule?

To qualify for Medicare coverage of a skilled nursing facility stay, you must first have a 3-day inpatient hospital stay. This means:

  • You must be formally admitted as an inpatient, not under observation or emergency status.
  • The stay must include three consecutive midnights in the hospital.
  • The day of admission counts, but the day of discharge does not.

For example, if you’re admitted on a Monday, stay through midnight on Wednesday, and are discharged on Thursday, your stay meets the 3-midnight requirement.

This rule exists because Medicare only covers skilled nursing facility care when it follows a qualifying inpatient hospital stay. Without it, you may be responsible for the full cost of care — which can add up quickly.

Why Observation Status Matters

A common point of confusion is the difference between being “admitted” and being “under observation.”
Even if you stay overnight or longer, observation status is considered outpatient care. Unfortunately, that time does not count toward the 3-day inpatient requirement.

Before you leave the hospital, ask a simple but crucial question:

“Was I officially admitted as an inpatient?”

Hospital staff can verify your status so you know whether your SNF stay will qualify for Medicare coverage.

    Are There Exceptions to the Rule?

    Yes — and they’re becoming more common. Some programs waive the 3-day requirement altogether:

    • Medicare Advantage Plans: Many Medicare Advantage (Part C) plans waive the 3-midnight rule, allowing coverage for SNF care without a prior hospital stay. Check with your specific plan to confirm.
    • Other programs: Medicaid or Veterans’ benefits may help cover costs if you don’t meet the Medicare rule.

    What You Should Do Before Leaving the Hospital:

    1. Confirm your admission status. Make sure your stay was inpatient, not observation.
    2. Talk to your care team. Ask if your hospital participates in any ACO or waiver program.
    3. Contact your Medicare plan. Whether you have Original Medicare or a Medicare Advantage plan, confirm coverage and potential exceptions before discharge.
