Summary & Overview
HCPCS Q4383: Axolotl Graft Ultra, Per Square Centimeter
HCPCS Level II code Q4383 represents an add-on billing code for an axolotl-derived graft product, reported per square centimeter. This code signals the use of a biologic graft material in addition to a primary surgical or wound-care procedure and has implications for product costing, supply chain tracking, and procedural documentation across care settings. Nationally, add-on product codes like Q4383 matter because they affect episode costs and provider billing detail when advanced graft materials are used.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for axolotl graft use, typical sites of service, and the billing role of an add-on per-square-centimeter product code. The publication summarizes benchmarks and payer coverage considerations, common modifier usage, and operational implications for coding and claims submission where available. If specific payer policies or pricing data are not provided in the input, those details are noted as unavailable.
This resource is intended for coding professionals, revenue cycle managers, and clinical leaders who need a clear, national-level summary of what HCPCS Level II code Q4383 represents and where it fits in procedural billing workflows.
Billing Code Overview
HCPCS Level II code Q4383 denotes an axolotl graft ultra, billed per square centimeter as an add-on, list separately in addition to primary procedure. The descriptor indicates a biologic graft product intended for use in wound repair or tissue replacement where the graft area is measured and reported by square centimeter.
Service type: Biologic graft product (per sq cm), add-on supply
Typical site of service: Hospital outpatient department, ambulatory surgery center, wound care clinic, or other procedural setting where grafting is performed

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with a large, non-healing full-thickness lower extremity wound following trauma and prior failed skin grafting presents to a hospital-based plastic surgery or wound care clinic. After debridement and wound bed preparation, the surgical team elects to apply an engineered amphibian-derived dermal replacement product billed as Q4383 (Axolotl graft ultra) as an adjunct to a primary reconstructive procedure. The product is billed per square centimeter as an add-on to the definitive procedure. Typical workflow: preoperative wound assessment and photography, sharp or surgical debridement, hemostasis, measurement of the defect in square centimeters, application and fixation of the biologic graft to the wound bed, dressing application, and scheduled postoperative wound checks and dressing changes in the outpatient wound clinic. The procedure is commonly performed in an operating room, procedure suite, or specialized wound care center under local, regional, or general anesthesia depending on patient comorbidities and concomitant procedures.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier — standard reporting | Use when no special circumstances or payment-affecting modifiers apply. |
| 22 | Increased procedural services | Use when the work required to place the graft is substantially greater than typical due to extensive debridement or complex wound bed preparation.
