Prolonged office service (outpatient - 15 min add-on) Evaluation Management
A prolonged office service is an add-on to an outpatient office visit when the clinician spends extra, medically necessary time beyond the typical work of the visit.
Overview
A prolonged office service is an add-on to an outpatient office visit when the clinician spends extra, medically necessary time beyond the typical work of the visit. It is reported in 15 minute increments and reflects additional same-day work tied to that visit. This extra time is often used for in-depth counseling, complex decision making, reviewing extensive outside records, medication reconciliation, or care coordination related to the visit.
Also known as: Prolonged services add-on (outpatient), Outpatient prolonged office add-on, 15 minute prolonged office add-on
