What 11765 covers
A clinician removes a wedge of skin from the nail fold, often to address an ingrown nail with painful or inflamed tissue along the nail edge. The service targets the surrounding skin fold; it is distinct from removing the nail plate or excising the nail matrix. It is commonly performed by a physician or other qualified practitioner in an office or outpatient procedure setting.
Select the code when the operative note supports excision of nail-fold skin, rather than nail trimming, nail avulsion alone, or nail-matrix removal. Document the affected nail, the fold tissue excised, and the reason for the procedure. Medicare assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in one 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. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

How to choose
- 11730Nail avulsionSingle nail plate

- 11750Nail matrix excisionPermanent partial or complete removal
- 11750 involves excision of the nail and matrix. This code is for wedge excision of nail-fold skin, without that broader target.
- 11755Nail biopsyDiagnostic tissue sampling
- 11755 is for diagnostic sampling of the nail unit. Use 11765 for therapeutic removal of nail-fold skin, not a biopsy.
11765 billing questions
How is this different from a nail avulsion?
This code describes excision of skin from the nail fold. A nail avulsion removes the nail plate; report that service only when the plate is separately removed.
When would 11750 be more appropriate?
Use 11750 when the procedure excises the nail and nail matrix, rather than removing a wedge of skin from the fold. The operative documentation should identify the tissue removed.
Can modifier 50 be used for procedures on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.
Are postoperative visits separately payable during the global period?
Related postoperative visits during the 10-day global period are included in the procedure payment.
Can an assistant or co-surgeon be billed?
Medicare does not pay an assistant at surgery for this procedure. Co-surgeons and team surgery are not permitted.
