Pressure ulcer surgery
About 15941: Ischial ulcer excision with ostectomy
Reports excision of an ischial pressure ulcer with removal of underlying bone and direct suture closure, rather than closure with a flap.
This operation removes a pressure ulcer over the ischial area and excises underlying bone as an ostectomy, followed by direct primary suture closure. It is typically performed in an operating room by a plastic or reconstructive surgeon, or another surgeon managing complex pressure injuries. A common clinical setting is a chronic ulcer over the ischial tuberosity in a patient with limited mobility, such as someone who uses a wheelchair.
Select this code when the operative report supports both ostectomy and primary closure; a skin or muscle flap represents a different technique. Documentation should identify the ischial site, ulcer excision, bone removal, and closure method. The code has 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 is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

15941 billing questions
How does this differ from 15940?
Both describe ischial pressure-ulcer excision with primary suture closure, but 15941 also includes ostectomy. Use the operative technique, not ulcer stage alone, to distinguish them.
Can the ostectomy or primary closure be billed separately?
Both are part of the service described by this code. The key distinction is that bone is removed and the wound is closed directly rather than with a flap.
When is a flap code more appropriate?
Choose a flap procedure when the surgeon closes the defect with a skin flap or prepares a muscle or myocutaneous flap, rather than using primary suture closure.
Should modifier 50 be used for ulcers on both sides?
No. CMS identifies bilateral adjustment as inapplicable to this code and modifier 50 as inappropriate for its descriptor or anatomy.
What documentation supports reporting 15941?
The operative report should establish the ischial ulcer site, excision of the ulcer, removal of underlying bone, and direct primary suture closure.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
