About A2018: Permeaderm C wound matrix
Report A2018 for each square centimeter of Permeaderm C wound matrix used with a qualifying wound procedure, rather than as a standalone service.
A2018 identifies Permeaderm C, a wound matrix applied to a wound as part of wound treatment. Physicians and other qualified practitioners may use it in settings where wound procedures are performed, including for chronic wounds such as diabetic foot ulcers or venous leg ulcers. The code represents the product quantity, not the clinician’s assessment or interpretation of the wound.
Report units based on the square centimeters of Permeaderm C used, and document the wound site, treated area, product, and quantity. CMS classifies A2018 as an add-on: bill it only with an appropriate primary procedure, with payment handled within that procedure’s global period. The code is technical-component-only; a separate code covers interpretation. Application procedure selection depends on the wound location and area, such as the applicable trunk, arm, or leg code versus the code for specified other sites.

A2018 billing questions
Can A2018 be billed by itself?
No. CMS classifies it as an add-on code, so it must be billed with an appropriate primary procedure and is paid within that procedure’s global period.
How are units counted?
Count the square centimeters of Permeaderm C used. The record should support the treated wound area and the quantity applied.
Which wound application code should accompany A2018?
Choose the primary application procedure based on wound location and area. For example, 15271 applies to qualifying trunk, arm, or leg wounds, while 15275 covers specified other sites.
Does A2018 include interpretation?
No. A2018 is technical-component-only; a separate code covers interpretation.
How does A2018 differ from A2016?
Both identify Permeaderm products billed by square centimeter, but A2018 identifies Permeaderm C and A2016 identifies Permeaderm B. Use the code that matches the product used.
