What Q4148 covers
Q4148 identifies Neox, Neox RT, or Clarix Cord placental tissue used as a biologic wound covering, commonly for chronic wounds such as diabetic foot or venous leg ulcers. Physicians, podiatrists, and surgeons may apply the product in an outpatient wound clinic or hospital setting after preparing the wound. Q4148 reports the product, not the clinician’s wound-preparation or application work.
Select this code for the named product and report units according to the square centimeters supplied. Documentation should identify the product, the treated wound and its measured area, and the amount applied. CMS classifies Q4148 as an add-on code: report it with the applicable primary wound-application procedure, and its payment falls within that procedure’s global period. CMS also classifies it as technical-component-only; a separate code represents interpretation.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
