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.

99152 billing questions
What is the minimum time needed to report 99152?
At least 10 minutes of intraservice time is required. Sedation lasting under 10 minutes is not reported separately.
When is 99153 added?
Report one unit of 99153 when total intraservice time reaches 23 minutes. Additional units begin at 38 minutes, 53 minutes, and each subsequent 15-minute mark.
Can 99152 be billed if no independent observer is present?
No. This code requires a trained observer to monitor the patient while the proceduralist directs sedation and performs the procedure.
How does this differ from sedation provided by a separate clinician?
For a patient age 5 or older, a separate physician or qualified health care professional providing sedation reports 99156, adding 99157 only when the time warrants it. For a younger patient, the separate-provider initial code is 99155.
Should 99152 be used with a Medicare screening or diagnostic colonoscopy?
No. When the endoscopist provides moderate sedation for Medicare GI endoscopy to a patient age 5 or older, report G0500 instead of 99152.
Does the presedation evaluation count toward sedation time?
No. Presedation assessment, consent, and recovery monitoring after the proceduralist’s face-to-face attendance ends are excluded from intraservice time.
