What Q4164 covers
Q4164 identifies Helicoll supplied for wound treatment, with quantity measured in square centimeters. It represents the product, not the clinician’s work to prepare the wound or apply the material. A wound-care clinician or surgeon may use it when treating a wound selected for this type of coverage, such as a chronic diabetic foot or venous leg ulcer. The clinical record should identify the wound site and size, the product used, and the quantity applied.
CMS classifies Q4164 as an add-on code: report it only with a primary procedure, and payment falls within that procedure’s global period. Report the applicable wound-application service separately; the product quantity should reflect the documented square centimeters. CMS designates Q4164 as technical-component-only, with interpretation covered by a separate code. Its listed relative values are practice expense only: 3.81 in both office and facility settings, with zero work and malpractice RVUs.
