[
Effective March 8, 2017, the Centers for Medicare &
Medicaid Services (CMS) requires that all hospitals and critical access
hospitals (CAH) provide the Medicare Outpatient Observation Notice (MOON) to
beneficiaries in Original Medicare (fee-for-service) and Medicare Advantage
enrollees who receive observation services as an outpatient for more than 24
hours.
The hospital or CAH must issue the MOON no later than 36 hours after
observation services as an outpatient begin. This also applies to beneficiaries
in the following circumstances:
- beneficiaries who do not have Part B coverage (as noted on the MOON,
observation stays are covered under Medicare Part B);
- beneficiaries who are subsequently admitted as an inpatient prior to the
required delivery of the MOON;
- beneficiaries for whom Medicare is either the primary or secondary
payer.
To access the MOON and completion instructions, please visit CMS?s website.
