HCPCS Code G0378: Hospital Observation Service, Per Hour

G0378 is billed per hour for hospital observation; G0379 is for direct admission to observation without ER or clinic visit.

Yes, G0378 can be billed alone, but generally requires 8 or more hours of observation to be reimbursed.

There is no CPT equivalent; G0378 is the HCPCS code used for hospital outpatient observation care per hour.
