What Q4243 covers

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.

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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
