Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a chronic, non-healing full-thickness or partial-thickness wound (for example, a lower-extremity venous stasis ulcer, diabetic foot ulcer, or surgical wound dehiscence) requiring adjunctive biologic dermal matrix application. The service Q4338 (Artacent velos, per square centimeter) represents an add-on billing element for area-based application of an acellular dermal matrix product used to provide a scaffold for tissue regeneration. Workflow: the patient is evaluated in an outpatient wound clinic or ambulatory surgery center; the wound is debrided and sized; hemostasis is achieved; the dermal matrix is trimmed to fit and applied to the wound bed and secured with sutures, staples, or fibrin sealant; appropriate dressings are placed; documentation includes wound measurements, product square centimeters used, lot numbers, and clinical rationale for the biologic scaffold. Typical sites of service include outpatient wound care centers, ambulatory surgical centers, and inpatient operating rooms for complex wounds.
