Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 99152 covers

99152 covers moderate sedation directed by the physician or other qualified health care professional performing the underlying procedure for a patient age 5 or older. During a bronchoscopy, cardiac catheterization, transesophageal echocardiogram, or image-guided intervention, the proceduralist remains face-to-face with the patient while an independent trained observer, often a nurse, monitors consciousness and physiologic status. These services occur in catheterization labs, hospital procedure suites, and equipped offices.

Report 99152 once for the initial sedation period when at least 10 minutes of intraservice time are documented. Time begins when the sedating agent is administered and ends when the proceduralist’s continuous face-to-face attendance ends. Add 99153 at 23 minutes, with further units at 38 minutes and each subsequent 15-minute mark. Exclude preassessment and recovery from intraservice time; document agents, doses, the observer, monitoring, and start and stop times. For Medicare GI endoscopy with sedation directed by the endoscopist, report G0500 instead. The office practice-expense value reflects resources supplied by the practice rather than a facility.
