What Q4270 covers
Q4270 identifies the Complete SL wound product supplied for wound treatment; it is not the application procedure itself. Wound-care clinicians may furnish it during an office or outpatient procedure in which a skin substitute product is applied to a wound. Report the code in square-centimeter units, using the documented product and area to determine the quantity. The code identifies a specific product, so another product’s HCPCS code is not interchangeable simply because it is used on a similar wound.
Q4270 is an add-on code and must be billed with a primary procedure; it is paid within that procedure’s global period. The record should identify Complete SL and support the quantity reported with the square centimeters treated. CMS classifies Q4270 as technical-component-only, with a separate code covering interpretation. Pair it with the applicable primary wound-application procedure, such as 15271 or 15275, selected according to the treated body site.
