About Q4142: XCM biologic tissue matrix application

Report Q4142 for each square centimeter of XCM biologic tissue matrix supplied with a primary wound procedure for wound coverage or tissue repair.

Q4142 identifies XCM biologic tissue matrix measured by the square centimeter. The matrix is used as a scaffold or covering in wound care, including treatment of wounds requiring a biologic matrix. Wound care clinicians, surgeons, and podiatrists may use it during an application procedure in an office, hospital outpatient department, or other setting where wound treatment is performed.

Report units based on the square centimeters of matrix applied, and pair the code with the primary procedure, such as an appropriate skin-substitute application code. Documentation should identify the wound, the matrix used, and the area applied so the reported units can be supported. CMS classifies Q4142 as an add-on: it is billed only with a primary procedure and its payment falls within that procedure's global period. CMS also identifies it as technical-component-only, with interpretation covered by a separate code.

Q4142 billing questions

How is the number of Q4142 units determined?

The code is measured per square centimeter. Report units based on the area of XCM matrix applied, supported by documentation of the treated wound and product area.

Can Q4142 be billed by itself?

No. CMS classifies it as an add-on code that must be reported with a primary procedure, such as an appropriate skin-substitute application service.

Which application code may be paired with Q4142?

The primary application code depends on the wound site and applicable procedure criteria. For example, 15271 applies to qualifying sites on the trunk, arms, or legs, while 15275 applies to qualifying sites such as the face, scalp, or neck.

Does Q4142 include interpretation?

CMS identifies Q4142 as technical-component-only and states that a separate code covers interpretation.

What documentation supports Q4142?

Document the wound treated, the use of XCM biologic tissue matrix, and the square centimeters applied. The recorded area should support the billed units.
