Medicare Outpatient Observation Notice (MOON)

12/12/2016
The MOON is a standardized notice to inform beneficiaries (including Medicare health plan enrollees) that they are an outpatient receiving observation services and are not an inpatient of the 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.

Medicare Outpatient Observation Notice and accompanying form instructions are available here. Manual instructions will be made available in the coming weeks. All hospitals and CAHs are required to provide the MOON beginning no later than March 8, 2017.

See "Federal Register - IPPS - NOTICE Act Final Rule" to view the final NOTICE Act regulation (Section L and 42 CFR 489.20).
