Medicare Outpatient Observation Notice

When a Medicare beneficiary receives outpatient observation services from a hospital or critical access hospital (CAH) for more than 24 hours, he or she (or the beneficiary’s authorized representative) must receive a Medicare Outpatient Observation Notice (MOON). The written MOON and a verbal explanation of the notice must be delivered no later than 36 hours after services were initiated. The MOON is mandated by the Federal Notice of Observation Treatment and Implication for Care Eligibility Act (NOTICE Act), enacted on Aug. 6, 2015.

Important notes:

• The MOON may be delivered before a beneficiary receives 24 hours of observation services as an outpatient
• If the beneficiary is transferred, discharged or admitted, the MOON still must be delivered no later than 36 hours following initiation of observation services
• The start time of observation services is measured as the clock time observation services are initiated in accordance with a physician’s order

Hospitals and CAHs must use the Office of Management and Budget (OMB)-approved MOON form, which can be downloaded from the Centers for Medicare & Medicaid Services (CMS) website  here :
