About Q4355: Abio XPL or XPL HY wound material

Report Abio XPL or Abio XPL HY by square centimeter when this material is supplied during a separately reported wound application procedure.

Q4355 identifies Abio XPL or Abio XPL HY material supplied for placement on a wound. A clinician performing the application may use the material as part of wound coverage in an office or facility. This code identifies the specific product, rather than the clinician’s work of preparing the wound and placing the material.

Select Q4355 only when the treatment record identifies Abio XPL or Abio XPL HY, and report the quantity in square centimeters. Document the product used, the wound site, the measured area, and the accompanying application procedure. CMS classifies Q4355 as an add-on code: it is billed with a primary procedure and paid within that procedure’s global period. CMS also classifies it as technical-component-only. Q4355 therefore represents the technical portion; a separate code covers interpretation when that service is reported.

CMS billing rules for Q4355

Global period

Q4355 billing questions

When is Q4355 reported instead of Q4356?

Use Q4355 for Abio XPL or Abio XPL HY. Q4356 identifies Abio MEM or Abio HYD; select the code that matches the documented product.

Does Q4355 replace the wound application procedure code?

No. Q4355 identifies the material by square centimeter and is billed with a primary procedure for its application.

How are units determined for Q4355?

The code is expressed per square centimeter. The record should identify the Abio product and support the quantity reported.

Is interpretation included in Q4355?

CMS classifies Q4355 as technical-component-only. A separate code covers interpretation when that service is reported.

How does the primary procedure’s global period affect Q4355?

Q4355 is an add-on billed with the primary procedure and paid within that procedure’s global period.

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.
