A parent can spend four nights in a Puget Sound hospital bed and still not qualify for Medicare-covered rehab. Here is how observation status works, how to catch it early, and what Washington families can do about it.
By Marcus Reyes, LSW · September 07, 2026
Original Medicare (Part A) will only pay for a skilled nursing facility stay if it follows a qualifying inpatient hospital stay of at least three consecutive midnights. The day of discharge does not count toward those three midnights. It sounds like a technicality, and for most families it stays invisible until a discharge planner mentions it on the way out the door.
The trap is that a hospital bed does not automatically mean inpatient. A patient can be placed in observation status, which Medicare treats as outpatient care billed under Part B, even while occupying a regular room, wearing a gown, and receiving IV fluids for three or four nights. Those nights do not count toward the three-midnight requirement. The result is a family that assumed twenty days of covered rehab and instead faces a private-pay bill from day one.
Two bills change. First, the hospital stay itself moves from Part A (one deductible, no per-service coinsurance) to Part B, where the patient owes 20% coinsurance on each outpatient service after the Part B deductible. Second, and usually larger, any skilled nursing rehab afterward is not covered by Part A at all.
Skilled nursing in the Puget Sound market runs into the hundreds of dollars per day when paid privately. Families who expected Medicare to carry the first weeks of recovery frequently pivot to a different plan entirely: hiring in-home care, or moving a parent into an assisted living community at roughly $6,000 to $8,000 a month, or a licensed adult family home at roughly $4,500 to $7,000. A third cost catches people off guard too. Under observation, self-administered drugs, including a parent's own daily medications given by hospital staff, are often not covered and get billed separately.
Ask directly, in writing, and ask again each day. The question is not "has Mom been admitted?" but "is my mother currently classified as inpatient or observation, and how many inpatient midnights has she accrued?" Status can be changed during a stay, sometimes more than once, and it can be changed retroactively while the patient is still in the building.
Federal rules require the hospital to give a Medicare Outpatient Observation Notice, called the MOON, both in writing and verbally when a patient has been in observation for more than 24 hours. It must be delivered no later than 36 hours after observation services begin. If you have not been handed a MOON, that is worth asking about. Case management at the large Puget Sound systems, including Harborview and UW Medical Center, Swedish, Overlake, EvergreenHealth, Providence Regional Medical Center Everett, and MultiCare Tacoma General, can tell you the current status and whether the attending physician believes an inpatient order is clinically justified.
Start with the treating physician, not the billing office. Status is a clinical determination, and if the physician documents that the patient's severity and expected length of stay meet inpatient criteria, the order can be written or corrected. A federal court ruling also established an appeal right for Medicare beneficiaries who were formally admitted as inpatients and then reclassified to observation during the stay, so if that reclassification happened to your parent, ask the hospital about appealing it.
Check the plan type as well. Medicare Advantage plans are not bound by the three-midnight rule the same way Original Medicare is, and many waive it entirely, but they typically require prior authorization for a skilled nursing admission. If your parent has an Advantage plan, the question shifts from counting midnights to getting the authorization approved before discharge.
Washington offers free, unbiased Medicare counseling through SHIBA, the Statewide Health Insurance Benefits Advisors program run by the Office of the Insurance Commissioner, reachable at 1-800-562-6900. SHIBA volunteers do this specific problem constantly and cost nothing.
If the midnights are not there and the appeal does not land, the practical question becomes what care your parent actually needs and how to pay for it. Sometimes that is a short course of in-home care while strength returns. Sometimes the hospitalization revealed that home was no longer workable, and the right answer is a licensed adult family home, an assisted living community, or memory care at roughly $7,500 to $9,500 a month.
Washington's Apple Health (Medicaid) with the COPES waiver, administered through DSHS Home and Community Services, covers personal care in adult family homes and many assisted living settings for those who qualify by income and assets, though it does not pay room and board outright. Eligible veterans and surviving spouses may add VA Aid and Attendance. Your local Area Agency on Aging can also help: Aging and Disability Services for King County, Homage for Snohomish County, and Aging and Disability Resources of Pierce County.
Before committing to any community, verify its license and inspection history free at the DSHS lookup, fortress.wa.gov/dshs/adsaapps/lookup. A local advisor can shortlist homes by care level, neighborhood, and Apple Health acceptance in the days you do not have to spare.
