Summary
CMS issued an updated Medicare Outpatient Observation Notice (MOON) on February 24, 2026, which BlueCross BlueShield of South Carolina now requires for all Medicare Advantage beneficiaries. The revised notice improves readability and design, is available in English and Spanish, and remains valid through February 28, 2029. Billing teams must ensure this notice is provided to patients receiving observation services to clarify they are outpatients, not inpatients.
Action Required
By March 25, 2026: Front desk and clinical staff must obtain and provide the updated MOON notice (available on the CMS website) to all Medicare Advantage beneficiaries at BlueCross BlueShield of South Carolina receiving outpatient observation services. Ensure both English and Spanish versions are available. Update intake processes and encounter workflows to document that the MOON notice was provided to the patient. Verify compliance during chart audits. Failure to provide the required notice may result in claim denials or compliance violations.
