Observation Status Medicare Maryland: Why Your Parent's Hospital Stay May Not Count

Your parent spent three nights in a Maryland hospital bed. You assumed Medicare would cover the rehab they need next. Then you learn they were under "observation status" the entire time — classified as an outpatient despite being in a hospital room — and none of those nights count toward the three-day inpatient requirement for Medicare-covered skilled nursing care.

This happens constantly, and it's the single most expensive surprise in hospital discharge planning.

The Three-Day Inpatient Rule

Medicare Part A covers skilled nursing facility (SNF) care only when the patient has been formally admitted as an inpatient for at least three consecutive days, not counting the day of discharge. Days spent under observation status are billed as outpatient services under Medicare Part B and do not count toward this requirement.

The practical consequence: if your parent needs rehab after a hospital stay but was under observation the entire time, Medicare won't pay for the SNF. The family either pays privately — often $300-$500 per day — or brings the parent home without the therapy they need.

The MOON Notice

Federal law requires Maryland hospitals to deliver a Medicare Outpatient Observation Notice (MOON) to any patient who receives observation services for more than 23 hours. This notice must be provided both verbally and in writing within 36 hours of the observation order.

The MOON explains:

• The patient's outpatient observation status
• That observation time does not count toward the three-day inpatient stay requirement
• The potential financial implications for subsequent skilled nursing care

If your parent has been in the hospital overnight and you haven't received a MOON, ask the nurse or case manager directly: "Is my parent classified as inpatient or observation?" Don't assume that being assigned a hospital room with a bed means inpatient admission.

What Families Can Do

Ask early and often. Within the first 24 hours of arrival, ask the admitting physician or hospitalist whether your parent is being admitted as inpatient or placed under observation. If they're under observation, ask what criteria would need to be met for conversion to inpatient status.

Request a status change. If your parent's condition worsens or they clearly meet the clinical criteria for inpatient care (typically needing hospital-level services for two or more midnights), ask the attending physician to change the classification. Physicians can convert observation to inpatient if medically justified.

File an appeal. If the hospital changes your parent's status from inpatient to observation, or if they refuse to convert observation to inpatient, the patient or authorized representative can file a fast-track appeal through Commence Health, Maryland's designated BFCC-QIO (888-396-4646).

Consider a Medicare Advantage exception. Some Medicare Advantage plans waive the three-day rule for in-network SNFs. Check your parent's plan documents.

The Real Cost

A parent who spends three days under observation and then needs rehab faces the full private-pay rate at a skilled nursing facility — potentially $15,000-$30,000 for a standard 20-day rehab stay that Medicare would have covered entirely. The observation status trap is the number-one reason families contact elder law attorneys after a hospitalization.
