Summary & Overview
CPT 17284: Destruction of Malignant Lesion on Face (3.1–4.0 cm)
CPT code 17284 covers the destruction of a malignant cutaneous lesion on highly visible or sensitive facial areas — including the face, ears, eyelids, nose, lips, or mucous membranes — when the lesion measures 3.1 cm to 4.0 cm in diameter. The code captures a set of destructive techniques such as chemosurgery, cryosurgery, and electrosurgery used in ambulatory or outpatient procedural settings. Nationally, this code is relevant for dermatology and surgical oncology providers billing for major lesion destruction on cosmetically and functionally important sites.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for using this code, typical sites of service, and the common payer landscape that governs coverage and documentation expectations. The publication provides benchmarks and billing considerations tied to lesion size thresholds, coding specificity, and procedural categorization. It also outlines where to look for policy updates and payer-specific rules that commonly affect prior authorization and claims adjudication.
This summary is intended to orient coders, practice managers, and revenue-cycle staff to the primary clinical and administrative significance of CPT code 17284 and to highlight the topics covered in greater detail in the full publication.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient presents to a dermatology clinic with a biopsy-confirmed malignant cutaneous lesion located on the left cheek measuring approximately 3.5 cm in greatest diameter. After discussion of treatment options, the dermatologic surgeon schedules a destruction procedure using electrosurgery in the outpatient dermatology procedure suite. The clinical workflow includes pre-procedure evaluation (history, medication review, anticoagulation assessment), informed consent, local anesthesia administration, lesion mapping and measurement, lesion destruction using the selected modality (e.g., electrosurgery, cryosurgery, or chemosurgery), hemostasis and wound care, and brief post-procedure observation with discharge instructions. Documentation includes lesion location, exact measurement (3.1–4.0 cm to meet 17284), malignancy confirmation or strong clinical suspicion, method of destruction, anesthesia used, any complications, and follow-up plan for surveillance or further oncologic care if indicated.
