Inpatient vs observation status in Medicare
Same bed, same hospital, very different bill.
You can spend a night or more in a hospital bed and still not be an inpatient. If the hospital keeps you under observation while doctors decide whether to admit you, you're an outpatient, and Medicare treats the stay very differently.
Why it matters
| Inpatient | Observation (outpatient) | |
|---|---|---|
| Which part pays | Part A, after the $1,736 deductible per benefit period | Part B: usually 20% coinsurance for each service, after the $283 deductible |
| Skilled nursing afterward | Days count toward the 3-day inpatient stay Part A requires | Days don't count toward the 3-day requirement |
| Drugs you usually take yourself | Covered as part of the stay | Generally not covered by Part B; your Part D plan may help |
The skilled nursing trap
Part A covers skilled nursing facility care only after at least 3 days as a hospital inpatient. If some or all of your stay was under observation, you might not qualify, and you could face the full cost of a skilled nursing facility. Medicare Advantage plans may waive the 3-day rule; check your plan.
The notice you should get
If you're an outpatient under observation for more than 24 hours, the hospital must give you a Medicare Outpatient Observation Notice (MOON) explaining your status and what it means for your costs.
What to ask
- "Am I an inpatient or an outpatient under observation?" Ask every day, since status can change.
- "If I'll need rehab afterward, will this stay qualify me for skilled nursing coverage?"
- If you disagree with your status, ask your doctor, and ask the hospital or Medicare about your appeal rights.
Common questions
Your doctor decides, based on Medicare rules and whether they expect you to need hospital care spanning at least two midnights.
Yes. Medigap plans help pay Part B coinsurance, which applies to observation services. They don't change the 3-day inpatient rule for skilled nursing.
