Moderate sedation
About 99153: Same-provider moderate sedation, additional time
Reports each additional 15-minute increment of moderate sedation when the physician or qualified health care professional also performs the underlying procedure.
Code 99153 represents additional intraservice time for moderate sedation provided by the physician or qualified health care professional performing the procedure that requires sedation. It may be relevant during services such as endoscopy, cardiac catheterization, or image-guided intervention when the procedural clinician provides the sedation and a trained observer assists with monitoring the patient’s level of consciousness and physiological status. Count the time spent providing the sedation service, not recovery time.
Report 99153 only with the related primary procedure and the appropriate initial same-provider sedation code, 99151 or 99152. Documentation should identify who performed the procedure and sedation, the observer, the patient’s monitored status, and the intraservice time supporting each additional unit. CMS treats this as an add-on code paid within the primary procedure’s global period. It is technical-component-only; a separate code covers interpretation.
