CPT code 22904 denotes an extensive surgical excision of a soft tissue malignant tumor of the abdominal wall when the tumor and necessary margins measure under 5 cm. This code captures procedures where resection extends beyond the tumor to include adjacent tissues or structures suspected of involvement, reflecting oncologic surgical intent to achieve clear margins. Nationally, accurate coding for these resections affects surgical quality measures, hospital and ambulatory surgical center billing, and oncology case mix classification.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of the clinical context for use of 22904, common payer coverage patterns and considerations, and the typical settings in which the service is provided. The publication outlines benchmarking elements relevant to surgical oncology billing and highlights policy or coding guidance updates where available. Practical operational topics covered include proper code selection based on tumor size and extent of excision, documentation elements that support use of 22904, and how this code interacts with facility versus professional billing across inpatient and outpatient surgical settings.
