Summary & Overview

CPT 17108: Cutaneous Vascular Destruction >50 cm2

CPT code 17108 denotes destruction of a cutaneous vascular proliferative lesion larger than 50 cm², typically performed with laser modalities such as Argon, pulsed dye, or YAG. The procedure is a non‑incisional, bloodless method of treating extensive vascular lesions and is primarily delivered in outpatient dermatology settings, ambulatory surgical centers, or appropriately equipped physician offices. Nationally, this code is relevant for clinicians who manage large vascular lesions and for payers that evaluate coverage and bundling of laser-based dermatologic procedures.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and which payers are commonly involved in reimbursement decisions. The publication summarizes benchmarking considerations, common modifier usage (where provided), and how this service is categorized for claims processing. It also outlines areas where data was not provided in the input, such as associated taxonomies, specific ICD-10 diagnoses, and related codes.

This brief provides a national perspective intended for clinicians, practice managers, and billing professionals seeking a clear description of the service represented by CPT code 17108 and the payer landscape relevant to claims and coverage discussions.

Billing Code Overview

CPT code 17108 describes cutaneous vascular destruction of a proliferative vascular lesion greater than 50 cm², typically performed with a laser (for example, Argon, pulsed dye, or YAG). The procedure is a bloodless surgical technique because no incision is made in the skin and tissue destruction is achieved through directed energy.

Service type: Laser or light-based vascular lesion destruction

Typical site of service: Outpatient dermatology clinic, ambulatory surgical center, or physician office equipped for laser procedures

Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.

Clinical & Coding Specifications

Clinical Context

A 35-year-old patient presents to a dermatology clinic with a longstanding, symptomatic port-wine stain (cutaneous vascular proliferative lesion) involving the right cheek and temple. The lesion has been monitored for growth and episodic bleeding after minor trauma. After evaluation, the dermatologist recommends cutaneous vascular destruction using a pulsed dye laser because lesion surface area exceeds 50 cm2. The patient is consented, medical history and medications reviewed, and pre-procedure photos taken. On the day of service the patient arrives to the dermatology outpatient procedure suite. Local anesthesia (topical or regional) is administered as indicated, protective eye shields are applied, and laser parameters are documented. The physician performs laser ablation in multiple treatment fields to cover the entire lesion (>50 cm2). Hemostasis is achieved with the laser; no incision is made. Post-procedure instructions for wound care and sun protection are provided, and follow-up is scheduled to assess response and potential repeat treatments. Typical sites of service include outpatient dermatology clinics, ambulatory surgery centers, and hospital outpatient departments. Typical service type: outpatient laser destruction of cutaneous vascular lesion (17108).
