Observation Status vs Inpatient Washington

Your Parent Is in a Hospital Bed but Medicare Says They Are an Outpatient

Your father has been in the hospital for two days. He has a bed, nurses check on him regularly, and he is receiving IV medications. Everything looks like a hospital admission. Then someone hands you a form explaining that he is actually under "observation status" — classified as an outpatient — and the financial consequences of this distinction are about to hit your family hard.

Observation status is one of the most consequential and least understood aspects of hospital care for Medicare beneficiaries. In Washington State, it determines whether Medicare Part A or Part B covers the stay, how much the patient pays out of pocket, and whether a subsequent skilled nursing facility stay will be covered at all.

How the Two Statuses Work

Inpatient admission is billed under Medicare Part A. The patient pays a fixed deductible ($1,736 in 2026) and Medicare covers the rest for up to 60 days. This status also starts the clock on a critical threshold: three consecutive inpatient days qualify the patient for Medicare-covered skilled nursing facility rehabilitation afterward.

Observation status is billed under Medicare Part B. The patient pays 20% coinsurance on every individual service — lab work, imaging, each nursing assessment. Self-administered medications (the pills the patient takes on their own) are charged at full retail price because Part B does not cover them during an outpatient stay. And the hours spent in observation do not count toward the three-midnight requirement for SNF coverage.

The financial difference can be staggering. A two-day observation stay with labs, imaging, and medication can generate thousands of dollars in Part B coinsurance. And if the patient needs rehab at a skilled nursing facility afterward, the family faces the full private-pay rate — often exceeding $10,000 per month — because the three-midnight threshold was never met.

The MOON Notice: What It Means When You Get One

If a patient has been under observation status for more than 24 hours, the hospital must deliver a Medicare Outpatient Observation Notice (MOON, Form CMS-10611). Federal rules require this notice within 36 hours of the observation services beginning.

The MOON is not just paperwork. It is a formal notification that:

• The patient is an outpatient, not an inpatient
• The stay is being billed under Part B, not Part A
• Observation hours do not count toward the three-midnight SNF threshold
• The patient's cost-sharing obligations are different from what they would be under an inpatient admission

When you receive a MOON, read it carefully. It should explain the patient's status and the financial implications. If it does not, ask the case manager or patient advocate to clarify in writing.

The CMS-10868 Appeal: Reclassification Rights

The landmark class action Alexander v. Azar (later Alexander v. Price) established appeal rights for Medicare beneficiaries whose status is reclassified from inpatient to observation during their stay. If the hospital initially admits your parent as an inpatient and subsequently downgrades the classification to outpatient observation, the hospital must deliver a Medicare Change of Status Notice (Form CMS-10868) at least four hours before discharge.

This reclassification right means families are no longer stuck accepting a status change without recourse. You can file an expedited appeal with Acentra Health, Washington's BFCC-QIO (helpline: 1-888-305-6759), to challenge the reclassification while the patient is still in the hospital.

The appeal asks Acentra to review the medical records and determine whether inpatient criteria were met. If Acentra agrees that the patient should have been classified as inpatient, the billing is corrected — the stay gets billed under Part A, and the three-midnight clock starts counting.

What If the Patient Was Always Under Observation (Never Reclassified)

The Alexander v. Azar appeal right specifically covers reclassification — situations where the hospital changed the patient's status from inpatient to observation. If the patient was placed under observation from the beginning and never reclassified, the appeal pathway is different.

In that scenario, your options include:

• Asking the attending physician to reconsider and formally admit the patient as inpatient. Physicians have the medical judgment authority to make this call, and a well-documented request explaining the patient's clinical needs can influence the decision.
• Filing a standard Medicare claim after discharge and appealing the denial through the five-level Medicare appeals process, starting with a redetermination by the Medicare Administrative Contractor.
• Contacting SHIBA (Statewide Health Insurance Benefits Advisors) through the Washington Office of the Insurance Commissioner for free counseling on navigating the appeal.

How to Protect Your Parent During the Hospital Stay

The most effective step you can take is monitoring the admission status from day one:

1. Ask on admission day: "Is my parent being admitted as an inpatient or placed under observation?" Do not assume — the patient can be in a hospital bed receiving extensive care and still be under observation status.

2. Track the inpatient days. Medicare counts the day of inpatient admission and does not count the day of discharge. Confirm with the hospital which inpatient days qualify before discharge.

3. Watch for the MOON or CMS-10868. If the hospital delivers either form, read it immediately. The MOON tells you observation status has been applied. The CMS-10868 tells you a reclassification has occurred. Both trigger specific action windows.

4. Act fast. The hospital must provide CMS-10868 at least four hours before discharge. Once you receive it, contact Acentra immediately and follow the notice's appeal instructions. Do not wait to "discuss with the family" — call Acentra first, then discuss.

The Downstream Impact on Skilled Nursing Coverage

The practical consequence that families miss until it is too late: under standard Original Medicare, if your parent spends three days under observation and then needs skilled nursing rehabilitation, Medicare will not cover the SNF stay. The patient must either pay the private rate (which in Washington averages over $14,000 per month) or apply for Medicaid — a process that takes 45 to 90 days and requires meeting strict income and asset limits.

This is why observation status is not just a billing classification. It is a financial fork in the road that determines whether your parent's recovery is covered by Medicare or paid entirely out of pocket.

For families navigating this situation in Washington, the Hospital-to-Home Transition Guide includes a day-by-day observation window tracker and the specific appeal scripts for both Acentra reclassification challenges and standard Medicare appeals — the tools you need to protect your parent's coverage before the discharge clock runs out.
