Summary & Overview
CPT 15786: Single-Lesion Skin Sanding (Superficial Resurfacing)
CPT code 15786 represents a dermatologic surface procedure—light sanding of the skin to remove a single lesion, such as a scar or an abnormal growth. This code captures a common minor surgical technique used in dermatology and plastic-reconstructive practices to improve superficial skin irregularities. Nationally, clear coding for this procedure matters for appropriate clinical documentation, accurate claims submission, and consistent payment across outpatient settings.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on the clinical context and coding definition, followed by practical information on payer coverage patterns and common modifiers used with this code. The publication summarizes benchmarks and payment considerations relevant to outpatient dermatologic services, highlights documentation elements that support medical necessity, and outlines areas where policy updates or payer-specific edits frequently affect claims for superficial skin resurfacing.
This resource is intended for billing professionals, practice managers, and clinicians seeking a national overview of CPT code 15786, how it is used in practice, and the topics to monitor when submitting and reviewing claims for single-lesion sanding procedures.
Billing Code Overview
CPT code 15786 describes a dermatologic procedure in which the provider removes a single lesion, such as a scar or an abnormal growth, by lightly sanding the surface of the skin with a specialized tool. This procedure is a form of dermabrasion or superficial resurfacing performed to improve skin contour, texture, or to remove superficial lesions.
Service type: Skin resurfacing / lesion removal
Typical site of service: Outpatient dermatology clinic or ambulatory surgical center, where minor dermatologic procedures are commonly performed.
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to an outpatient dermatology clinic with a cosmetically bothersome, stable hypertrophic scar on the cheek from a prior laceration. Conservative measures have been tried and the patient requests a minimally invasive resurfacing procedure to improve surface irregularity and texture. The provider evaluates the lesion, documents informed consent, photographs the area, and confirms no active infection or contraindicating medical conditions. On the day of service the patient is prepped, topical or local anesthesia applied as appropriate, and the provider performs a single lesion abrasion using a specialized dermabrasion device to lightly sand the surface of the skin. Hemostasis is achieved, wound care instructions are reviewed, and a follow-up visit is scheduled to assess healing and outcomes.

78 | Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | When an unplanned return to treat a complication related to the procedure occurs |
80 | Assistant surgeon | When an assistant surgeon is required and documented for the procedure |
62 | Two surgeons | When two surgeons work together as primary surgeons performing distinct portions of the procedure |
26 | Professional component | When only the professional component is billed separately from the technical component (rare for this service) |
59 | Distinct procedural service | When another procedure is performed on a separate lesion or distinct anatomic site during the same encounter |
