HCPCS Q4127: Talymed, Per Square Centimeter (Advanced Wound Care)
HCPCS Level II code Q4127 designates Talymed wound matrix material billed per square centimeter as an add-on supply in conjunction with a primary procedure. This code captures use of an advanced biologic wound product applied to managed wounds and is relevant for outpatient wound care clinics, hospital outpatient departments, and specialty centers. Nationally, accurate coding of advanced wound care products affects payer coverage determinations, supply cost accounting, and quality measurement for complex wound management.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical context, practical considerations for claim submission, common modifiers that may be applied, and benchmarking considerations for supply-line reimbursement. The publication outlines typical sites of service, the add-on nature of the code (to be billed in addition to a primary procedure), and the role of per-square-centimeter pricing in cost and utilization reporting.
This summary provides the foundation for operational guidance on documentation and claim structuring, payer policy comparison, and benchmarking for advanced wound care supplies. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A patient with a non-healing partial- or full-thickness wound (for example, a chronic venous stasis ulcer or a diabetic foot ulcer) presents to an outpatient wound clinic or hospital-based wound care service. After initial evaluation, conservative measures (offloading, compression, debridement, infection control, optimization of perfusion and glycemic control) are performed. When a clinician determines that an advanced biologic dressing is indicated to promote granulation and epithelialization, Q4127 (Talymed, per square centimeter) is ordered as an adjunct to standard wound procedures. Typical workflow: wound measurement and documentation, wound bed preparation (sharp or enzymatic debridement as clinically indicated), application of Talymed to the cleaned wound bed in the appropriate square-centimeter quantity, securement with secondary dressings, and post-application wound care instructions and follow-up scheduling. The procedure is billed as an add-on supply per square centimeter in addition to any primary wound procedures or debridement codes performed on the same date of service.
