What 11771 covers
A surgeon excises extensive pilonidal disease involving the skin and underlying tissue of the cleft between the buttocks near the tailbone. The condition may include a cyst or sinus tracts. General surgeons commonly perform the procedure in a facility operating room; it may also be performed in an office setting. The wound is managed according to the operative plan.
Choose this level when the operative findings and work support extensive disease, rather than a simple or complicated excision. Document the location and extent of the disease, sinus tracts or involved tissue, and what was removed. This major surgery has a 90-day global period: the day-before preoperative visit and related postoperative care during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

- Use 11770 for simple pilonidal excision. Use 11771 when the documented extent supports an extensive excision.
- 11772Pilonidal excisionComplicated disease
- 11772 is for complicated pilonidal excision; 11771 is the extensive level. The operative findings and work support the distinction.
- 10081Pilonidal drainageComplicated incision and drainage
- 10081 represents complicated incision and drainage, not excision. Select it when the service is drainage rather than removal of extensive pilonidal disease.
11771 billing questions
How does this code differ from 11770?
11771 is for extensive pilonidal disease excision; 11770 is for a simple excision. Base the choice on the documented disease and operative work, not on the diagnosis alone.
How does this code differ from 11772?
11772 describes complicated pilonidal disease excision. Use 11771 when the documented extent supports an extensive excision rather than a complicated one.
Can this be reported for incision and drainage?
No. This code represents excision of extensive pilonidal disease. Incision and drainage is represented by a different code family, such as 10080 or 10081, depending on the service.
Can modifier 50 be used for disease on both sides?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.
Is postoperative wound care separately reported during the global period?
Related postoperative care during the 90-day global period is included, as is the day-before preoperative visit.
Can an assistant surgeon or co-surgeon be paid?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
