About 11471: Complex hidradenitis excision, perineal region
Reports complex surgical removal of hidradenitis-affected skin and underlying tissue in the perianal, perineal, or umbilical region.
This code is for complex excision of skin and subcutaneous tissue affected by hidradenitis in the perianal, perineal, or umbilical region. Surgeons, including dermatologic and general surgeons, may perform the procedure in an operating room or an outpatient surgical setting to remove diseased tissue in these specified locations. The code distinguishes this service from the simple or intermediate excision service for the same regions.
Select the code based on the anatomic site and the complex nature of the procedure, and document the involved location, extent of excision, and operative details supporting complexity. The code includes a 90-day global period, covering 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% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

11471 billing questions
When should 11471 be selected instead of 11470?
Use 11471 for complex excision in the perianal, perineal, or umbilical region. Use 11470 when the excision in those regions is simple or intermediate.
How does the site affect code selection?
11471 is for hidradenitis excision in the perianal, perineal, or umbilical region. Axillary and inguinal excisions are represented by different codes.
Is closure separately reported?
The code distinguishes complex excision from the simple or intermediate service for these sites. Do not separately report the closure as though it were the simple or intermediate service.
Can modifier 50 be used for bilateral disease?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
What documentation supports reporting 11471?
Document the perianal, perineal, or umbilical site, the hidradenitis-related tissue removed, and operative details supporting the complex service.
What assistant-surgeon and global rules apply?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. Assistant-at-surgery payment requires documented medical necessity; 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
