What Q4173 covers
Q4173 identifies the Palingen or Palingen Xplus wound product supplied for application to a wound. Wound-care clinicians, surgeons, and other practitioners performing skin substitute applications may report it in outpatient or facility settings. The product code represents the material, not the clinician’s application work; the clinical record should identify the product and the quantity used. This code is billed per square centimeter.
Report Q4173 only with a primary procedure, such as the appropriate skin substitute application code for the treated site and wound area. Documentation should support the product used, the amount applied, the wound treated, and the related application procedure. CMS classifies Q4173 as an add-on code paid within the primary procedure’s global period. It is a technical-component-only code; a separate code covers 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.
