The 100-day SNF benefit is one of the most misunderstood pieces of Medicare. It only applies when the patient had a qualifying inpatient hospital stay of at least 3 nights (observation status does not count) and is admitted to a Medicare-certified SNF within 30 days for a related skilled need — typically rehab after stroke, hip fracture, joint replacement, or major cardiac event.
Coverage is not guaranteed for the full 100 days. Days 1–20 are fully covered. Days 21–100 carry a daily copay ($204/day in 2025 — verify the current-year amount). And the SNF must certify that the patient is still making measurable progress on skilled goals. Once progress plateaus, the skilled benefit ends even if the calendar has not run out — often around day 20–30 in practice.
When the SNF benefit ends, families face three choices: long-term facility placement (typical Michigan nursing home cost is far higher than home care), private-pay home care, or a hybrid. Home care in Southeast Michigan runs Personal Care $29–$37/hr and Specialized Care $35–$42/hr at typical 2026 agency rates; live-in is $400–$500/day. Most families who choose home care start with a 4-to-8 hour daytime block.
The MI Choice Medicaid waiver, long-term care insurance, and VA Aid & Attendance can each pick up part of the home-care cost after the SNF benefit ends. Plan the exit at least a week before the discharge date — coverage transitions are rarely reversible.

Related questions
- Does observation status count toward the 3-night rule?
- No. Only true inpatient nights count. Ask the hospital case manager to confirm admission status before discharge.
- Can the SNF end coverage early?
- Yes. Coverage ends when the patient stops progressing on skilled goals, which often happens well before day 100.
- What is the fastest way to set up home care when the SNF benefit ends?
- Call the home care agency 5–7 days before the SNF discharge date. Most Southeast Michigan agencies can start within 24–48 hours of the family approving the care plan.
