What 11770 covers

A surgeon excises a simple pilonidal cyst or sinus in the cleft near the tailbone, removing the lesion and involved tissue or tract. The procedure is commonly performed in an outpatient operating room, though a suitable simple case may be treated in an office setting. The operative report should show that excision was performed and describe the disease and extent of the work.

Choose this code for the simple-excision level, not for drainage alone or a more extensive or complicated excision. Document the operative findings and the basis for the selected level. CMS assigns a 10-day global period, so related postoperative visits 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 multiple-procedure reduction. Bilateral adjustment is inappropriate. CMS does not pay an assistant at surgery for this code and does not permit co-surgeon or team-surgery billing.

11770 billing questions

How does 11770 differ from 11771 or 11772?

Use 11770 for simple excision. The higher family codes describe more extensive or complicated excision; the operative findings and work performed should support the selected level.

Can 11770 be reported for draining a pilonidal abscess?

No. When the service is incision and drainage rather than excision, consider the pilonidal drainage codes 10080 or 10081, as appropriate to the procedure.

Are related postoperative visits separately billable?

Related postoperative visits during the 10-day global period are included in the procedure payment.

Can modifier 50 be used for pilonidal excision?

No. CMS identifies bilateral adjustment as inappropriate for this code and its anatomy.

Can an assistant or co-surgeon be billed with 11770?

CMS does not pay an assistant at surgery for this code and does not permit co-surgeon or team-surgery billing.

What happens if another procedure is performed in the same session?

The highest-valued procedure is paid in full, while other procedures are subject to the standard multiple-procedure reduction.
