Benefits A-Z

Observation Services

Outpatient observation stays are a covered benefit when a hospital places a patient under observation, but has not admitted him or her as an inpatient. These services generally occur after an emergency room visit or after an outpatient surgical procedure (ambulatory surgery). While outpatient observation stays generally should not exceed 23 hours, up to 48 hours are covered when medically necessary.

The costs for these services are based on the related services: emergency room costs or ambulatory surgery costs. If an observation stay is for more then 48 hours, the costs for inpatient hospitalization or inpatient hospitalization for mental health will apply.
