What Q4147 covers
Q4147 identifies Architect ECM PX FX, a wound matrix used in wound care. A wound-care clinician, surgeon, or podiatrist may apply the product to a wound in an office wound clinic or hospital outpatient setting. The code represents the named product, not a general skin substitute; the product documented for the encounter must match Architect ECM PX FX.
Report the quantity in square centimeters and retain documentation identifying the product, treated wound, amount used, and associated primary procedure. CMS classifies Q4147 as an add-on, so it must be billed with a primary procedure and is paid within that procedure’s global period. CMS also classifies it as technical-component-only; interpretation is represented by a separate code. Q4147 has no physician work RVUs in the supplied CMS facts, while its practice-expense RVUs reflect the technical resources associated with the service.
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.
