About 20100: Penetrating neck wound exploration
Operative exploration of a penetrating neck wound is reported when a surgeon examines the wound and underlying tissues to assess injury.
CPT 20100 describes operative exploration of a penetrating wound in the neck, such as a stab or gunshot wound. The surgeon examines the wound tract and underlying tissues to assess the extent of injury and identify affected structures. Trauma or general surgeons commonly perform this work in a hospital operating room. Routine inspection, cleaning, or closure of a superficial wound is not the same service as operative exploration.
Select the code based on the wound’s neck location and the documented operative exploration, not simply the mechanism or apparent wound size. The operative report should identify the site, exploration performed, findings, and any injuries or repairs. Related postoperative visits are included in the 10-day global period. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral performance with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.

20100 billing questions
How is 20100 distinguished from the other penetrating-wound exploration codes?
Use 20100 for a penetrating wound in the neck. The related codes distinguish chest, abdomen/flank/back, and extremity locations.
Does a penetrating mechanism alone support 20100?
No. The record should support operative exploration of a penetrating neck wound; the mechanism alone does not establish that the exploration was performed.
Are postoperative visits separately reported during the global period?
Related postoperative visits during the 10-day global period are included in the procedure.
How is 20100 paid when other procedures are performed in the same session?
The highest-valued procedure is paid in full; other procedures performed in that session are subject to the standard 50% multiple-procedure reduction.
Can modifier 50 or an assistant-at-surgery payment apply?
For bilateral performance, modifier 50 is paid at 150%. Assistant-at-surgery payment may be made, but co-surgeons and team surgery are not permitted.
