Summary & Overview
HCPCS Level II Q4372: Amchoplast Excel, Per Square Centimeter
HCPCS Level II code Q4372 designates Amchoplast Excel, billed per square centimeter as an add-on supply in addition to a primary procedure. This code identifies a dermal or soft-tissue implant or adjunct material used during surgical or wound-repair procedures and matters nationally because it standardizes reporting for per-area billing of specialty implantable materials. Accurate use of the code ensures appropriate itemization when clinicians apply additional biologic or synthetic matrices that are charged by area rather than bundled into procedural fees.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find guidance on the clinical context for use of this add-on supply code, the typical sites of service where it is applied, and the implications for claims submission and coding consistency. The publication outlines common modifiers and points of attention for billing without making clinical recommendations. It also summarizes how this code interacts with primary procedure reporting and where to expect variability across payers. Where specific contractual or coverage details are required, the document advises consulting payer policies directly. Data not available in the input.

Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents for surgical management of a soft-tissue defect following excision of a benign skin lesion on the lower leg. The primary procedure is surgical excision with local flap reconstruction. During closure, the surgeon applies an amchoplast excel dermal substitute to a 12 cm² area to augment soft-tissue coverage and promote dermal regeneration. The product is billed as an add-on material per square centimeter using Q4372 in addition to the primary surgical CPT code for excision and flap closure.
The clinical workflow: the patient is evaluated preoperatively with history, focused skin exam, and consent for excision and potential reconstructive materials. Intraoperatively, after lesion excision and hemostasis, the reconstructive plan is executed; the surgeon measures the defect and applies the dermal matrix product over the 12 cm² defect, secures it as needed, and completes soft-tissue closure. Documentation includes the brand-name product, square centimeters applied, lot number if required by facility policy, and correlation to primary procedure. Billing includes the primary procedure CPT(s) and the add-on HCPCS Level II code Q4372 with any applicable modifiers documenting unusual circumstances.
