What 15940 covers

This operation removes a pressure ulcer over the ischial region and closes the resulting wound directly with sutures. It is selected when the surgeon can bring the wound edges together without using a skin or muscle flap. Surgeons commonly perform it in an operating room for patients with chronic pressure injuries, including people with limited mobility or paraplegia.

Report 15940 when the operative documentation identifies the ischial site, excision of the ulcer, and primary suture closure. The choice changes when the surgeon performs an ostectomy or uses flap reconstruction. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

15940 billing questions

When should 15940 be chosen over an ischial flap-closure code?

Use 15940 when the excised ischial ulcer is closed directly with sutures. A skin or muscle flap procedure belongs to the corresponding flap-closure code.

How does 15940 differ from 15941?

15940 describes primary suture closure. 15941 is the related ischial procedure that includes ostectomy.

Can modifier 50 be used for ulcers on both sides?

No. Modifier 50 is inappropriate for this code under the CMS bilateral rule. The documentation should identify the treated ischial site or sites.

Is postoperative care separately reported during the global period?

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

Can an assistant surgeon or co-surgeon be reported?

Medicare 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.
