What 99417 covers
CPT 99417 represents additional physician or qualified health professional time spent on a qualifying office or other outpatient evaluation and management service. It is an add-on to the primary E/M service, not a stand-alone visit code. The clinician’s prolonged work is associated with the outpatient encounter; this code is distinct from prolonged services provided by clinical staff and from prolonged inpatient or observation E/M services.
Each unit represents a 15-minute increment. The record should support the qualifying outpatient E/M service and the additional clinician time reported. Medicare assigns 99417 status I under the physician fee schedule: Medicare does not accept this code for reporting and payment. For Medicare prolonged office or outpatient E/M reporting, use G2212 instead.
