CPT code 21086 documents the creation of an auricular prosthesis by taking a custom impression of the patient’s ear. Auricular prostheses restore form and cosmetic appearance for patients with partial or total ear loss from surgery, trauma, or congenital conditions. This procedure is clinically significant because it supports reconstructive and rehabilitative goals, often improving psychosocial outcomes and enabling better fitting of prosthetic devices.

Key payers included in the national analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage considerations, common modifier usage, and the clinical context in which 21086 is employed.
