What A2019 covers
A2019 represents Kerecis MariGen, a fish-skin wound matrix supplied by the square centimeter for application to a wound. Wound-care clinicians, surgeons, and other practitioners who treat wounds may use it as a wound covering in settings such as an office or outpatient department. The product supply is distinct from the procedure that prepares and applies a skin substitute to the wound.
Report A2019 only with a primary procedure that applies the product; it is not a standalone service. Document the product used, the treated wound, and the amount supplied so the reported units reflect the square centimeters involved. Select the primary application procedure based on the wound's site and area. CMS treats A2019 as an add-on paid within the primary procedure's global period. It is a technical-component-only code, with interpretation covered by a separate code.

A2019 billing questions
Can A2019 be reported by itself?
No. CMS identifies it as an add-on code, so it must be reported with a primary procedure.
Which procedure is reported with A2019?
Pair it with the applicable wound skin-substitute application procedure, selected according to the wound's site and area.
How are units determined?
A2019 is measured per square centimeter. Document the product and the square-centimeter amount supplied.
Does A2019 include the wound application procedure?
No. A2019 represents the Kerecis MariGen product supply; report the primary procedure for applying the product separately.
How does the global-period rule affect billing?
A2019 is paid within the global period of its primary procedure and is not separately paid as a standalone service.
What does the technical-component designation mean?
CMS identifies A2019 as technical-component-only; a separate code covers interpretation.

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.
