What 99253 covers

Code 99253 represents a specialist’s evaluation requested by another physician or qualified health care professional to address a clinical question during a hospital inpatient or observation stay. The consultant assesses the patient and relevant records, develops an opinion or recommendations, and communicates findings to the requesting clinician. It may apply to a new or established patient; ongoing subsequent hospital management is a different service.

For Medicare, status I means 99253 is not valid for reporting and payment. Medicare uses initial inpatient or observation E/M codes 99221, 99222, or 99223 instead, as appropriate. For payers that recognize inpatient consultation codes, 99253 corresponds to low medical decision making or a 45-minute time level. It is reported as one service, not as a per-unit code.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
