Frequently asked questions

Patients for hospital observation can receive outpatient services directly without first visiting the emergency department. Observation status is used when patients need ongoing short-term assessment but do not meet inpatient hospital care criteria.

Documentation must record hours spent in observation care, all medical interventions or significant procedures performed, and any associated emergency room or ed or clinic visit preceding observation.

G0379 should be billed using the observation code for the direct admission of patient, capturing the start date and duration of observation services. Separate payment may apply for services rendered on the same claim form, including any initial service codes, critical care, or surgical procedures performed during the observation period.
