Hospitals: New Medicare Outpatient Observation Notice form required April 1 

Hospitals and critical access hospitals (CAH) must give the standardized Medicare Outpatient Observation Notice (MOON) to people who receive Medicare benefits and are observed as outpatients for more than 24 hours.

There is a new MOON form hospitals and CAHs are required to use beginning April 1, 2020.

When and how to use the MOON form

The MOON form lets patients know why they are not considered to be inpatient and provides information about their cost sharing and hospital coverage. It must be explained verbally and completed for individuals receiving outpatient observation services before they have received more than 24 hours of observation. The notice must be provided no later than 36 hours after observation services are initiated or, if sooner, upon release. Patients must sign to confirm they received and understand the notice. If they refuse, the staff member who gave the patient the notice must certify that it was presented.
