Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 10140 covers

This service involves making an incision to drain a hematoma, seroma, or other localized fluid collection. A clinician may perform it in an office, clinic, or facility when a collection—such as a postoperative seroma or a localized hematoma—requires drainage through an incision. The procedure is distinct from needle aspiration and from drainage directed at an abscess or a complex infected postoperative wound.

Document the collection’s location and clinical nature, the incision and drainage performed, and the circumstances supporting that approach. The code has a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple procedure reduction. Modifier 50 is inappropriate. Medicare does not pay for an assistant at surgery, and co-surgeons and team surgery are not permitted.
