Annual Reminder: Medicare Outpatient Observation Notice (MOON) Required

December 19, 2018

As of March 8, 2017, 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. This includes people with Blue Cross Medicare Advantage (PPO)SM, and Blue Cross Medicare Advantage (HMO)SM health plans.

This notice lets people know why they are not inpatients and what their cost sharing and hospital coverage will be. It must be explained verbally and completed no later than 36 hours after observation begins or sooner if patients are admitted, transferred or released. Patients must sign to confirm they received and understand the notice. If they say “no,” the staff member who gave the notice must certify that it was presented.

The MOON and what to do with it can be found at the Centers for Medicare & Medicaid Services website Learn more about third-party links.
