Wound care

About Q4243: AmchoMatrix wound product by area

Report AmchoMatrix by the square centimeter when this wound product is furnished with a primary wound-application procedure.

Q4243 identifies AmchoMatrix, a wound product supplied and measured by area. It may be used in wound care when a clinician applies the product to a wound as part of a primary procedure. Wound-care clinicians, podiatrists, and surgeons may encounter it in outpatient wound clinics, offices, or hospital settings. The product code represents the material, not the clinician’s wound preparation or application service.

Report the quantity in square centimeters and pair Q4243 with the primary procedure for the wound application. The record should identify the product and document the treated wound and the amount furnished. CMS classifies Q4243 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period. It is also a technical-component-only code; a separate code covers interpretation.

Q4243 billing questions

How is Q4243 different from Q4242?

Q4243 identifies AmchoMatrix and is measured per square centimeter. Q4242 identifies Amniocyte Plus and is measured per 0.5 cc; select the code for the product actually furnished.

Can Q4243 be billed by itself?

No. CMS identifies it as an add-on code that must be billed with a primary procedure. For wound application, the primary procedure may be selected from the applicable skin-substitute application codes.

What documentation supports the units?

Document that AmchoMatrix was used, identify the treated wound, and record the amount furnished in square centimeters.

Does Q4243 include interpretation?

No. CMS classifies Q4243 as technical-component-only; a separate code covers interpretation.

How does the global-period rule affect payment?

Q4243 is paid within the global period of the primary procedure with which it is reported.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
