Summary & Overview
HCPCS L8020: Breast Prosthesis, Mastectomy Form
HCPCS Level II code L8020 designates a breast prosthesis, mastectomy form — an external prosthetic device used to restore breast shape after mastectomy. Nationally, this code matters for post-mastectomy rehabilitation, durable medical equipment (DME) coverage determinations, and supply billing across outpatient and DME settings. Coverage and reimbursement practices for mastectomy prostheses affect access to reconstructive options and patient out-of-pocket costs.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of typical sites of service and clinical context for the prosthesis, plus a summary of the payer landscape used in benchmarking.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult assigned female at birth who has undergone unilateral or bilateral mastectomy for treatment of breast cancer or prophylaxis. After surgical healing and prosthetic fitting evaluation, the patient is fitted with a breast prosthesis such as a mastectomy form (L8020) to restore breast contour and symmetry within clothing and for psychosocial rehabilitation. The clinical workflow includes 1) surgeon documents mastectomy and orders external prosthesis in the post-operative plan; 2) patient is referred to a certified mastectomy fitter or durable medical equipment (DME) supplier; 3) measurement and selection of an appropriate L8020 mastectomy form (size, laterality, adhesive/backing, material) is performed; 4) fitting session, patient education on wear/cleaning, and documentation of medical necessity (e.g., mastectomy operative note, scar maturity) are completed; 5) DME supplier dispenses the prosthesis and submits claim with appropriate modifier(s) and diagnosis pointers to the payer. Typical site of service is an outpatient prosthetic/accommodation clinic, DME supplier location, or ambulatory surgical center for fitting visits when performed concurrently with other outpatient services.
