Medicare Outpatient Observation Notice (MOON)

The MOON is a standardized notice to inform Medicare beneficiaries (including health plan enrollees) that they are outpatients receiving observation services and are not inpatients of a hospital or critical access hospital (CAH).  

The MOON is mandated by the Federal Notice of Observation Treatment and Implication for Care Eligibility Act (NOTICE Act), passed on August 6, 2015.  The NOTICE Act requires all hospitals and CAHs to provide written and oral notification under specified guidelines.

Full instructions related to MOON implementation ("CR9935 MOON Instructions") are available under “Downloads” below. The MOON instructions will be included as Section 400 of Chapter 30 of the Medicare Claims Processing Manual.
