What 27603 covers

The surgeon makes an incision to reach and drain a deep abscess or hematoma in the leg or ankle. Orthopedic, trauma, and general surgeons may perform the service when a deep collection requires operative drainage, commonly in a hospital or other surgical setting. The operative report should identify the leg or ankle site, establish that the collection is deep, and describe the incision and drainage performed.

Select this code for a deep abscess or hematoma, not a superficial skin abscess, bursal collection, or collection in the thigh or knee region. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral services reported with modifier 50, CMS pays 150%. Assistant-at-surgery payment is statutorily restricted; 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 is bilateral drainage paid?

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.
