Medicare: Skilled Nursing Facility Coverage

Medicare: Skilled Nursing Facility Coverage

Skilled Nursing Facility (SNF) care is one of the most critical care transitions families face. Medicare does provide coverage for SNF care under specific circumstances — but that coverage is limited, conditional, and often misunderstood.

This guide explains how Medicare SNF coverage actually works, what it pays for, and how long benefits last.

What Is Skilled Nursing Facility Care?

Skilled nursing facilities provide short-term, medically necessary care for individuals recovering from:

• Hospital stays (post-acute care)
• Surgery
• Acute illness
• Rehabilitation needs

This is distinct from long-term residential care or custodial care. SNFs in California are licensed and regulated by the California Department of Social Services under Title 22 and by the Centers for Medicare & Medicaid Services (CMS).

The Three Conditions for Medicare Coverage

Medicare Part A (hospital insurance) covers SNF care only when all three of these conditions are met:

1. A Qualifying Hospital Stay

You must have been admitted to the hospital as an inpatient (not observation) for at least 3 consecutive calendar days. The 3-day requirement is strict — observation stays do not count, regardless of how long you stayed or what was done to you.

2. Admission Within 30 Days

You must be admitted to the SNF within 30 calendar days of hospital discharge. If you go home first or wait longer than 30 days, you lose eligibility for SNF coverage under this hospital stay.

3. Medical Necessity

Your physician must determine that you need skilled nursing or rehabilitation services that cannot be provided at home or in an outpatient setting. This determination must be documented in medical records and must relate to the condition treated during your hospital stay.

What Medicare Part A Covers

When all three conditions are met, Medicare Part A covers:

• Room and board at a Medicare-certified SNF
• Skilled nursing care
• Physical therapy, occupational therapy, speech therapy
• Medications, medical supplies, and equipment
• Laboratory and diagnostic tests
• Meals

The Coverage Timeline: Days 1–100

Medicare SNF coverage is NOT unlimited. Coverage is structured as follows:

Days 1–20: Fully covered by Medicare Part A. You pay nothing (assuming you've met your Part A deductible).

Days 21–100: Covered by Medicare Part A, but you pay a daily copayment. For 2026, this copayment is $200 per day. After 100 days in a benefit period, Medicare stops paying, and you are responsible for all costs.

After Day 100: You are responsible for 100% of SNF costs. This is where Medicaid, supplemental insurance (Medigap), or personal funds become critical.

The Benefit Period

Medicare uses "benefit periods" to count SNF days. A new benefit period begins when you're admitted to the hospital as an inpatient. If you need SNF care again after your current benefit period ends, you start fresh with a new 100-day allotment — provided you've had a 60-day break from inpatient hospital or SNF care.

Understanding benefit periods is essential for planning long-term care costs.

What Medicare Part A Does NOT Cover

• Long-term custodial care
• Care that is primarily personal (bathing, dressing, feeding) rather than skilled
• Room and board at facilities not Medicare-certified
• Care that is "not reasonable or necessary"

Common Misconceptions

"Medicare will cover 100 days of skilled nursing facility care." This is misleading. Medicare will cover up to 100 days per benefit period, but only if all conditions are met. Many people don't qualify at all.

"Once I'm in an SNF, I'm covered for as long as I need it." No. Coverage ends at day 100 of your benefit period, or earlier if your physician determines skilled care is no longer medically necessary.

"SNF care is free if I'm on Medicare." You pay nothing for days 1–20, but from day 21 onward, you owe a daily copayment. After day 100, you owe everything.

Preparing for SNF Care Costs

If you anticipate needing SNF care, consider:

• Supplemental insurance (Medigap): Some Medigap plans cover a portion of the daily copayment from days 21–100.
• Medicaid planning: If SNF care will extend beyond 100 days, Medicaid can cover costs after Medicare stops, but only if you meet income and asset limits. Planning early is critical.
• Long-term care insurance: If you have this, review your policy for SNF coverage and waiting periods.
• Personal savings: Many families need to pay SNF costs out-of-pocket after Medicare coverage ends.

How to Verify SNF Medicare Certification

Before admission, verify the facility is Medicare-certified. You can:

• Ask the hospital discharge planner
• Check Medicare's nursing home compare tool at Medicare.gov
• Contact the facility directly

The Role of Your Physician

Your doctor's assessment of medical necessity is crucial. Doctors can sometimes disagree about whether skilled care is appropriate. If your doctor believes you no longer need skilled care, Medicare will stop coverage even if you haven't reached day 100.

If you disagree with an early discharge determination, you have appeal rights.

State Variations

California has additional regulations and protections for SNF residents through CDSS. Facilities must maintain specific staffing ratios, comply with inspection requirements, and address resident complaints.
