What Q4342 covers

Q4342 identifies Theramend, a wound-covering tissue product, measured by the square centimeter. It represents the product supplied for application to a wound, not the clinician’s work applying it. Wound care clinicians, surgeons, and other practitioners who treat wounds may use it in outpatient or facility settings when Theramend is applied as part of a wound treatment. The procedure code describes the application; Q4342 identifies the specific product used.

Report the quantity in square centimeters and document the product name, the treated wound, and the amount applied. Pair Q4342 with the applicable primary application procedure, such as billing code 15271 or 15275 when appropriate to the site and wound area. CMS treats this as an add-on code paid within the primary procedure’s global period, not as a standalone service. CMS classifies it as technical-component-only; a separate code covers interpretation. CMS assigns no physician-work RVUs to Q4342.

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.

Q4342 billing questions

Can Q4342 be billed by itself?

No. CMS identifies Q4342 as an add-on code that must be billed with a primary procedure, with payment included within that procedure’s global period.

How should the number of units be determined?

Report the Theramend quantity by square centimeter. Documentation should identify the product and the amount applied to the treated wound.

Which application code is reported with Q4342?

Use the primary skin-substitute application procedure appropriate to the wound site and area, such as billing code 15271 or 15275 when applicable.

Does Q4342 include the clinician’s application work?

No. Q4342 identifies the Theramend product; the primary procedure code represents the application service.

Does Q4342 include interpretation?

No. CMS classifies Q4342 as technical-component-only and specifies that 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.
