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.

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.

How does 10140 differ from abscess drainage?

10140 is for a hematoma, seroma, or other fluid collection. For incision and drainage of a simple or single abscess, consider 10060; more extensive or multiple abscess drainage is described by 10061.

Are related postoperative visits separately payable during the global period?

Related postoperative visits for 10 days are included in the global period for 10140.

Can modifier 50 be reported for bilateral drainage?

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 10140. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
