What 27301 covers

A surgeon opens the deep tissue planes of the thigh or knee region to evacuate a collection such as an abscess, infected bursa, or hematoma. Orthopedic surgeons commonly perform this service in an operating room, although the appropriate setting depends on the patient and the collection. The operative report should establish the site and depth and describe the collection and its drainage. A superficial skin abscess, a collection within bone, and a knee-joint procedure represent different services.

Report the code when the documented work is deep incision and drainage in the thigh or knee region, not excision of a mass or drainage limited to the skin. This major surgery code includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery; 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.

27301 billing questions

How does this differ from drainage of a superficial abscess?

This code is for a deep collection in the thigh or knee region. A collection confined to the skin or superficial tissue is considered under the applicable superficial abscess drainage code.

What documentation supports reporting this code?

Document the thigh or knee location, the deep tissue site, the type of collection, and the incision-and-drainage work performed. The record should distinguish a deep soft-tissue or bursal collection from a joint or bone process.

Can another drainage code be reported for the same collection?

Do not report a second drainage code for the same collection simply to represent its incision or evacuation. The operative documentation should identify any distinct, separately treated site.

How is bilateral treatment reported?

For bilateral procedures reported with modifier 50, CMS pays 150%.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be billed for this procedure?

CMS does not pay an assistant at surgery for this code. 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.
