Step-by-Step Guide to Billing Outpatient Observation
When The Observation Time Starts

Rounding And Recording Observation Hours
Once the total billable time is calculated, CMS needs to round to the nearest complete hour. Observation time reported using HCPCS code G0378, with the total number of rounded hours listed as units on one claim line.
Pausing Observation For Procedures
Observation facilities mustn’t overlap with procedures that already involve active ministering. If such a procedure occurs, the observation time should pause during that period. It might betemporarily paused to permit for essential detection or therapeutic procedures.
Opps Payment Rules For Observation
Under OPPS, observation services might qualify for separate payment only if certain conditions are met. Generally, medicare needs:
- At least 8 Billable hours of G-0378.
- A qualifying ED visit, Clinic Visit, essential care facilities, or direct admission to observation reported with G-0379.

Medicare patients who stay in observation for more than 24 hours must receive the Medicare Outpatient Observation Notice (MOON). The MOON must be provided within 36 hours of observation starting or sooner if the patient is discharged, admitted, or transferred. Documentation of the MOON delivery must be maintained in the medical history.

There is no national maximum, but longer remains need strong documentation, understanding resume clinical essential. Some Medicare Administrative Contractors and Commercial Payors impose stricter restrictions, often 48 to 72 hours. Medical billing services must always adhere to payer-specific policies.
