About 11451: Axillary hidradenitis excision, complex repair
Reports excision of axillary skin and subcutaneous tissue for hidradenitis when the resulting wound is managed with complex repair.
This code is for surgical removal of skin and underlying subcutaneous tissue affected by hidradenitis in the axilla, with complex repair of the resulting wound. Dermatologic, general, or plastic surgeons may perform the procedure, commonly in a facility setting for more extensive disease. The code is specific to the axilla; disease at other sites uses the corresponding hidradenitis excision code for that location.
Choose this code when the axillary excision is accompanied by complex repair, rather than simple or intermediate repair. Document the operative site and laterality, excision performed, and repair details supporting the complex level. The repair is included in this service and should not be separately unbundled. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

11451 billing questions
When should 11451 be chosen over 11450?
Both cover axillary hidradenitis excision. Choose 11451 when the wound receives complex repair; 11450 is for simple or intermediate repair.
Can the complex closure be billed separately?
No. Complex repair is part of 11451, so it is not separately reported as a repair service for the same wound.
How is bilateral axillary surgery reported?
Report modifier 50 for a bilateral procedure. CMS pays the bilateral service at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How does CMS handle other procedures performed in the same session?
The highest-valued procedure is paid in full; additional procedures are paid at 50%. Assistant-at-surgery payment requires documented medical necessity.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
