CPT code 11922 designates additional surface area for medical tattooing used to provide permanent camouflage of skin color defects caused by congenital anomalies, breast reconstruction, burns, vitiligo, birthmarks, and similar conditions. The code applies to each additional 20.0 cm2, or part thereof, beyond the initial treated 20.0 cm2, making it a unit-based add-on for procedures where pigment implantation covers larger areas. Nationally, this code matters for clinicians in dermatology and plastic surgery and for payers managing coverage and payment for reconstructive and restorative services.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for use of CPT code 11922, typical sites of service, and the unit-based nature of the code. The publication also summarizes benchmarks and payer policy patterns where available, highlights relevant coding practice considerations for surface-area billing, and outlines how this code fits within reconstructive and dermatologic service lines. Data not available in the input is noted where applicable.
