Medicare Skilled Nursing Facility Rules in Oregon: Coverage, Costs, and Limits

Your parent is leaving the hospital and the discharge planner says they need "rehab in a skilled nursing facility." Medicare covers that, right? It depends — and the rules are more restrictive than most Oregon families expect.

Medicare Part A covers skilled nursing facility care only under specific conditions, with hard limits on duration and escalating daily copays that can reach hundreds of dollars. Here's exactly how it works.

The Three Requirements for Medicare SNF Coverage

Medicare Part A covers skilled nursing facility care only when all three conditions are met:

1. A medically necessary inpatient hospital stay of at least three consecutive midnights. Observation status days don't count. If your parent spent three days in the hospital under observation status, they have zero qualifying days.

2. The SNF admission generally happens within 30 days of the hospital discharge. If your parent goes home first and their condition worsens after 30 days, the clock has expired.

3. The patient needs daily skilled care — physical therapy, occupational therapy, speech therapy, or skilled nursing services like wound care or IV medications. Custodial care alone (help with bathing, dressing, meals) doesn't qualify.

The 100-Day Coverage Structure

When all three requirements are met, Medicare Part A covers SNF rehabilitation on a tiered schedule:

• Days 1-20: Medicare pays 100% of the cost. No copay.
• Days 21-100: Medicare pays the facility rate minus a daily copay that the patient (or their supplemental insurance) must cover. In 2026, this copay is $217 per day.
• After day 100: Medicare coverage ends completely. The patient is responsible for the full private-pay rate, which averages $280-$350 per day at Oregon SNFs.

That means days 21-100 can cost the family $217 per day — roughly $6,510 per month — unless a Medigap supplemental policy or the Oregon Health Plan picks up the copay.

When Medicare Cuts Off Coverage Early

Medicare doesn't guarantee 100 days. Coverage can end when the patient no longer meets Medicare's coverage criteria for daily skilled care. In practice, many Oregon families see coverage terminated at 20-40 days.

The SNF must issue a Notice of Medicare Non-Coverage (NOMNC) at least two days before services end. If you believe your parent is still improving, file a fast appeal with Acentra Health (1-888-305-6759) by noon of the day before the scheduled termination. This triggers an immediate coverage freeze while the appeal is reviewed.

Oregon's PHEC Benefit: The Safety Net Most Families Miss

For parents enrolled in the Oregon Health Plan through a Coordinated Care Organization, Post-Hospital Extended Care (PHEC) was expanded by Senate Bill 296, passed in 2025 and effective January 1, 2026. PHEC covers up to 100 days of skilled nursing care for OHP members who meet Medicare's clinical criteria but lack Medicare coverage — including those blocked by the observation status three-midnight requirement.

The CCO administers PHEC directly from its global budget. The family doesn't apply separately — the CCO care coordinator should initiate it. If they don't, call the CCO's member services line and request PHEC coverage explicitly.

What Happens After Medicare Runs Out

When Medicare SNF coverage ends, families face three options:

• Private pay at the facility's full daily rate ($280-$350/day in Oregon)
• Oregon Medicaid long-term care — requires meeting strict financial eligibility (assets at or below $2,000, income at or below $2,982/month or establishment of a Miller Trust)
• Transition home with K Plan Community First Choice services or Oregon Project Independence

The transition from Medicare-covered rehab to Medicaid-funded long-term care is where most families lose time and money. Starting the Medicaid application early — while your parent is still in the SNF under Medicare — is critical because processing takes 45-90 days.

The Hospital-to-Home Oregon toolkit includes a Medicare SNF coverage tracker and timeline calculator that maps your parent's specific situation against all three funding sources.
