About Q4199: Cygnus wound matrix supply

Report Q4199 for each square centimeter of Cygnus Matrix supplied with a primary wound procedure involving application of a skin substitute.

Q4199 identifies the Cygnus Matrix product used in wound care, measured by the area supplied in square centimeters. It represents the product, not the clinician’s work of preparing the wound or applying the matrix. Clinicians may use it when treating an appropriate wound in an outpatient or other setting where the product is supplied and applied as part of wound management.

This is an add-on code: report it only with an appropriate primary procedure, and Medicare pays it within that procedure’s global period. Document the product and the square centimeters supplied, along with the treated wound and the primary procedure. CMS assigns Q4199 technical-component-only status; a separate code covers interpretation. The code has no physician work RVUs in the supplied CMS facts, so its valuation is not based on separately reported physician work.

Q4199 billing questions

How is the number of Q4199 units determined?

Report the square centimeters of Cygnus Matrix supplied. The record should support the product used and the measured amount.

Can Q4199 be billed by itself?

No. CMS identifies it as an add-on code, so it must be billed with an appropriate primary procedure.

Which primary procedure may accompany Q4199?

Use the applicable wound procedure for the treatment performed, such as a skin-substitute application code when that procedure describes the service. The wound site and extent determine the appropriate application code.

Is Q4199 the code for applying the matrix?

No. Q4199 represents the Cygnus Matrix product per square centimeter; the primary procedure reports the wound treatment or application service.

What documentation supports Q4199?

Record the wound treated, the Cygnus Matrix product supplied, the square centimeters used, and the associated primary procedure.

How does the global-period rule affect Q4199?

Medicare pays Q4199 within the global period of the primary procedure with which it is reported.
