What Q4156 covers
Q4156 identifies Neox 100 or Clarix 100 placental-tissue material used as a wound covering, measured by square centimeter; it represents the material, not the clinician’s work applying it. These products may be used in outpatient wound care, including treatment of diabetic foot ulcers or venous leg ulcers. A physician, podiatrist, or other qualified practitioner typically applies the material after preparing the wound bed in a clinic or hospital outpatient department.
Report the product quantity in square-centimeter units and pair the code with the primary wound-treatment procedure. Documentation should identify the product, wound site, amount used, and associated application service. CMS classifies Q4156 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period. It is also technical-component-only; a separate code covers interpretation.
