Medicare's skilled nursing benefit is short, conditional, and almost always ends sooner than families expect. Here's how to use the rehab window to line up long-term care across King, Snohomish, and Pierce counties.

After a qualifying inpatient hospital stay, Medicare Part A can cover up to 100 days of skilled nursing facility care per benefit period. Days 1–20 are covered in full; from day 21 through day 100 a daily coinsurance applies, which a Medigap plan or Medicare Advantage benefit may pick up. Nursing homes providing that care are licensed in Washington under RCW 18.51 and surveyed by DSHS Residential Care Services.
The number families miss is not 100 — it is the real one. Coverage lasts only as long as your parent needs and is benefiting from daily skilled care. When therapy plateaus, coverage ends, even if that is day 18. In practice, most Puget Sound rehab stays run two to four weeks, not three months. Treat 100 days as a ceiling that almost nobody reaches, not a plan.
Before coverage ends you should receive a written Notice of Medicare Non-Coverage, generally at least two days before the last covered day. It is not merely paperwork — it starts a clock. You have the right to a fast appeal through Medicare's Beneficiary and Family Centered Care Quality Improvement Organization, and if you file by the deadline on the notice, care typically continues while the review is decided.
Appeal when the notice genuinely does not match what you are seeing — your mother is still gaining ground in therapy, or an infection or fall has set her back. An appeal buys days, not months, so file it and keep planning at the same time. Never let the appeal replace the search for what comes next.
The rehab stay is the best planning runway most families ever get, and the most commonly wasted one. Start touring in week one. Ask the SNF's therapy team directly for their discharge projection and expected level of assistance — whether your father will need one-person or two-person transfers, help with medications, or a secured dementia setting decides which communities can even accept him.
In the Puget Sound region that usually means choosing among a licensed adult family home (up to six residents, roughly $4,500–$7,000 a month), assisted living (about $6,000–$8,000), or memory care with a Specialized Dementia Care endorsement ($7,500–$9,500). For someone leaving rehab still needing heavy hands-on help, an adult family home often delivers more one-to-one attention than a large campus, at a lower price. Verify any license and inspection history free at the DSHS lookup, fortress.wa.gov/dshs/adsaapps/lookup.
Medicare does not cover long-term custodial care, so the day rehab ends the bill usually shifts to private pay or a benefit program. Apply for Washington Apple Health with the COPES waiver through DSHS Home and Community Services early — the financial determination and CARE functional assessment take time you will not have later, and Medicaid-contracted beds are limited in some neighborhoods. Eligible veterans and surviving spouses should also check VA Aid & Attendance, and workers should check what they have earned through the WA Cares Fund.
Ask the SNF social worker to make the referral the week you arrive rather than the week you leave. Your Area Agency on Aging can help in parallel: Aging and Disability Services in King County, Homage in Snohomish County, and Aging & Disability Resources of Pierce County. Whether the rehab followed a stay at Harborview, UW Medicine, Swedish, Overlake, EvergreenHealth, Providence Everett, or MultiCare Tacoma, the pattern is the same — families who start in week one choose, and families who start in week three take whatever has an opening.
