What 15946 covers
This operation treats a pressure wound over the ischial region when reconstruction requires a muscle or myocutaneous flap. A reconstructive or plastic surgeon typically performs it in an operating room, often for a deep, chronic wound in a patient with limited mobility. The operative report should identify the ischial site, describe ulcer excision, and document preparation of the muscle or myocutaneous flap; wound depth alone does not establish the flap method.
Report the code for the documented ischial procedure and flap approach, rather than a skin-flap or primary-closure code. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose
- 15944Pressure ulcer excision
- Both address an ischial pressure ulcer, but 15944 describes skin-flap closure. Use 15946 when the documented reconstruction involves a muscle or myocutaneous flap.
- 15945Skin flap closure
- This code describes an ischial skin-flap procedure with ostectomy. Distinguish it from 15946 by the flap type and whether the operative service includes ostectomy.
- 15936Pressure ulcer excision
- The flap approach is similar, but 15936 is for a sacral pressure ulcer. Use 15946 for the ischial site.
15946 billing questions
How does this differ from the ischial skin-flap code?
Choose this code when the operative report documents preparation of a muscle or myocutaneous flap. The skin-flap code describes reconstruction using a skin flap instead.
Is ulcer excision reported separately?
The code encompasses the ischial ulcer excision with preparation of the specified flap. Do not separately report the excision as though it were an independent procedure.
Does this code include an ostectomy?
The code selection distinguishes procedures that include ostectomy from those that do not. Use the operative report to determine whether bone was removed and select the corresponding code.
Can modifier 50 be used for ulcers on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 is not the way to report bilateral anatomy.
How does the global period affect postoperative visits?
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 reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeons are payable only with supporting documentation; team surgery is 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.
