Summary & Overview
CPT 17003: Destruction of Premalignant Lesions, Add-On (2–14 Lesions)
CPT code 17003 designates an add-on procedure for the destruction of premalignant skin lesions beyond the first lesion treated in the same encounter. Specifically, it applies to the second through the fourteenth lesion, with each unit representing a single lesion destroyed by methods such as chemosurgery, cryosurgery, electrosurgery, or similar techniques. This code matters nationally because it standardizes billing for multi-lesion destruction encounters commonly performed in dermatology and procedural dermatology settings, impacting reimbursement workflows and claims processing for high-volume lesion treatments.
Key payers evaluated include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will gain a concise overview of the code’s clinical scope, typical sites of service, and how it relates to first-lesion and 15-or-more-lesion codes. The publication outlines coding relationships and common clinical scenarios where 17003 is appropriate, highlights payer coverage considerations, and summarizes operational implications for billing multiple lesions in a single visit. The content is intended to support billing, coding, and revenue cycle teams in ensuring accurate unit reporting and aligning clinical documentation with the correct add-on billing sequence for premalignant lesion destruction.
Billing Code Overview
CPT code 17003 describes an add-on destruction procedure for premalignant skin lesions. This code is used when a provider destroys the second through the fourteenth premalignant lesion during the same patient encounter, with one unit representing a single lesion. Techniques include chemosurgery, cryosurgery, electrosurgery, or other destructive methods.
Service Type: Destruction of premalignant integumentary lesions (add-on)
Typical Site of Service: Outpatient dermatology clinic, ambulatory surgical center, or physician office
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents to a dermatology clinic with multiple premalignant and benign cutaneous lesions on the forearms and trunk identified during a full skin exam. The provider documents one larger actinic keratosis removed as the first lesion and proceeds to treat multiple additional smaller lesions using cryosurgery and electrosurgery during the same encounter. Each additional lesion beyond the first is counted and reported separately using the add-on destruction code.
The clinical workflow includes pre-procedure consent and lesion mapping, local anesthesia if indicated, sequential destruction of lesions (chemosurgery, cryosurgery, or electrosurgery), brief hemostasis or topical dressing, and post-procedure instructions for wound care and signs of infection. Documentation specifies the total number of lesions treated, technique(s) used for each lesion, size and anatomic site of lesions, the primary lesion billed with the primary code for first lesion, and itemized units for each subsequent lesion billed with the add-on code 17003 (one unit per lesion for lesions 2–14).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service on the same day | When a separate E/M visit is performed and documented on the same date as the destruction procedure |
52 | Reduced services | When the procedure is partially reduced or not completed as planned |
53 | Discontinued procedure | When the procedure is terminated due to patient condition or unforeseen clinical events |
59 | Distinct procedural service | When another distinct procedure is performed at a separate anatomic site and needs differentiation |
76 | Repeat procedure by same physician | When the same procedure is repeated later the same day by the same provider |
77 | Repeat procedure by another physician | When repeated later the same day by a different provider |
LT | Left side | When documenting laterality for lesions on the left side of the body |
RT | Right side | When documenting laterality for lesions on the right side of the body |
50 | Bilateral procedure | When identical procedures are performed bilaterally and payer accepts bilateral modifier coding |
22 | Increased procedural services | When work required is substantially greater than typically required for this procedure |
23 | Unusual anesthesia | When general anesthesia is medically necessary for the procedure instead of local anesthesia |
59 | Distinct procedural service | When procedures that are usually bundled must be reported separately due to distinct anatomic sites or sessions |
95 | Synchronous telemedicine service rendered via real-time interactive audio and video | When parts of pre- or post-procedure evaluation were performed via live telehealth and payer allows |
52 | Reduced services | When limited treatment is performed and partial units or scaling of service is applicable |
