Summary & Overview
HCPCS Q4214: Cellesta Cord, Per Square Centimeter (Add-on)
HCPCS Level II code Q4214 designates the Cellesta cord billed per square centimeter as an add‑on supply to be reported in addition to a primary procedural code. As an add‑on HCPCS Level II item, Q4214 is used when a specific biologic cord product is applied or implanted during a primary operative or procedural service and must be reported separately to capture the additional material used. This code is relevant across surgical specialties that use grafting, biologic scaffolds, or implantable cord-like materials.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a national overview of the code’s clinical context, billing placement as an add‑on supply, and implications for site-of-service reporting. The publication summarizes typical use cases, payer coverage considerations, and how Q4214 interfaces with primary procedure reporting and reimbursement workflows. Data not available in the input is noted where applicable, and the content focuses on national policy and billing practice implications rather than state‑specific guidance.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult undergoing a dermatologic or wound-related procedure in an outpatient surgical suite or ambulatory clinic where a biologic dermal matrix product (Cellesta cord) is applied to a prepared wound or surgical bed. The patient often presents with a chronic nonhealing wound (for example, diabetic foot ulcer or venous stasis ulcer), a surgical defect after excision of a skin cancer, or a traumatic soft-tissue deficit requiring placement of a biologic scaffold. The workflow includes wound assessment, debridement or excision under local or monitored anesthesia care, measurement of the defect in square centimeters, selection of an appropriately sized Q4214 product billed per square centimeter as an add‑on to the primary procedure, placement and fixation of the graft/matrix, and dressing application. Typical sites of service are outpatient hospital departments, ambulatory surgical centers, and specialty dermatology or wound care clinics. Documentation includes indication, wound measurements, primary procedure CPT code(s), product lot number and size, clinician who applied the product, and any intraoperative complications.
