What 11755 covers
A clinician obtains tissue from a nail unit for diagnostic evaluation, such as when persistent nail dystrophy, an unexplained pigmented band, or a suspected nail-unit lesion needs assessment. Dermatologists, podiatrists, and other clinicians who treat nail disorders commonly perform the procedure in an office or procedural setting. The sampled structure may be the nail plate, bed, or matrix, depending on the abnormality and the diagnostic question.
Choose this service for tissue sampling, not routine trimming, debridement, or removal of a nail plate without a biopsy. Document the affected nail, the sampled nail-unit structure, the technique, and the clinical reason for obtaining tissue. The 0-day global period includes same-day preoperative and postoperative care. 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. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose
- 11750Nail matrix excisionPermanent partial or complete removal
- 11755 obtains tissue for diagnosis; 11750 is used for excision of the nail and matrix as a therapeutic procedure.
- 11730Nail avulsionSingle nail plate
- 11730 reports simple removal of a nail plate. Use 11755 when tissue from the nail unit is sampled for diagnostic evaluation.
- 11104Punch biopsySingle skin lesion
- 11104 describes a punch biopsy of skin. Use 11755 when the sampled structure is part of the nail unit rather than periungual skin alone.
11755 billing questions
When is this reported instead of nail avulsion?
Report 11755 when tissue is sampled for diagnosis. Nail plate removal alone, without diagnostic tissue sampling, is a different service.
Is routine nail debridement included as a biopsy?
No. Trimming or debriding dystrophic nails is not diagnostic tissue sampling; 11755 requires a biopsy of the nail unit.
What documentation supports the service?
Record the affected nail, the nail-unit structure sampled, the method used, and the clinical finding or diagnostic concern prompting the biopsy.
Can modifier 50 be used when both sides are treated?
No. CMS identifies the bilateral adjustment as inapplicable and modifier 50 as inappropriate for this service.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's payment.
Can an assistant or another surgeon be reported?
Assistant-at-surgery payment requires documentation of 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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
