Inpatient vs. Outpatient: Why It Matters

> About 54% of beneficiaries are in Medicare Advantage, where hospital cost-sharing follows plan rules; Original Medicare uses the Part A deductible and coinsurance. (Source: CMS / KFF, 2024.)

Inpatient Status

• Formally admitted to the hospital
• Doctor's order for inpatient admission
• Part A coverage applies
• Qualifies you for skilled nursing facility coverage afterward

Observation Status

• Technically outpatient, even if you stay overnight
• Part B coverage applies (higher cost-sharing)
• Does NOT qualify you for SNF coverage
• Hospital must inform you of observation status within 36 hours

Ask about your status: If you're in the hospital, ask whether you're admitted as inpatient or under observation.

MA plans must cover at least what Original Medicare covers, but cost-sharing differs:

Common MA Hospital Costs:

• Fixed copay per day (often $200-$400/day for first few days)
• Out-of-pocket maximum protects you from unlimited costs
• Some plans have $0 hospital days

Check your MA plan's specific hospital benefits before any planned procedure.
