What Q4126 covers
Q4126 identifies the supply of Memoderm, DermaTranZ, or InteguP, products in the skin-substitute and wound-matrix category. It is associated with wound-care procedures in which a clinician places the selected material over a prepared wound bed. Wound-care physicians, surgeons, and other clinicians who treat wounds may furnish it in office or hospital settings. The code represents the named product, not a general wound assessment or the clinician’s application work.
Report Q4126 only when one of these products was supplied, and document the product, wound site, amount used, and related primary procedure. CMS identifies it as an add-on code: 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, with interpretation covered by a separate code. Do not report Q4126 for another matrix merely because it serves a similar wound-care purpose.
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.

Q4126 billing questions
When should a claim use Q4126 rather than another wound-matrix code?
Use Q4126 when the product furnished is Memoderm, DermaTranZ, or InteguP. A similar purpose does not make another product reportable under this code.
Can Q4126 be billed by itself?
No. CMS identifies it as an add-on code that must be reported with a primary procedure.
How does the global-period rule affect Q4126?
CMS pays Q4126 within the primary procedure’s global period. Report it with the primary procedure rather than as a standalone service.
What documentation supports reporting Q4126?
Document which named product was furnished, the wound site, the amount used, and the related primary procedure.
Does Q4126 include interpretation?
CMS classifies Q4126 as technical-component-only; a separate code covers interpretation.
