About Q4135: Mediskin skin substitute supply

Report Q4135 for Mediskin supplied for wound coverage, measured by the product amount used and paired with the applicable skin-substitute application procedure.

Q4135 identifies Mediskin, a skin-substitute product used to cover wounds as part of wound care. The product may be furnished in an office or hospital outpatient setting when a clinician applies a skin substitute to a wound. This code represents the product supply, not the clinical work of preparing and applying it. The associated application procedure is selected separately according to the wound site and treated area.

Report Q4135 only with a primary procedure, and document the product used and the square-centimeter quantity supported by the record. The application note should identify the wound and treated area, while the supply record should support the Mediskin amount billed. CMS classifies Q4135 as an add-on code paid within the primary procedure’s global period. It is also a technical-component-only code; a separate code covers interpretation.

CMS billing rules for Q4135

Q4121

Skin substitute

TheraSkin per square centimeter

$139.47

Q4121 identifies TheraSkin, not Mediskin. Use the code for the product furnished rather than choosing by wound location alone.

Q4124

Wound matrix

Oasis tri-layer product

$139.47

Q4124 identifies Oasis tri-layer wound matrix. Q4135 is specific to Mediskin; the product record determines which code applies.

Q4132

Wound matrix

Grafix Core or GrafixPL Core

$139.47

Q4132 identifies Grafix Core or GrafixPL Core. It is not a substitute code for Mediskin, even when both products are used in wound care.

Q4135 billing questions

How is Q4135 different from another skin-substitute code?

Q4135 identifies Mediskin specifically. Select the product code for the material actually furnished; codes for other skin substitutes are not interchangeable merely because they are used for wound coverage.

What primary procedure should accompany Q4135?

Report it with the skin-substitute application procedure appropriate to the wound site and treated area. For example, the applicable code may be from the 15271–15278 application-code family.

How should the units be supported?

The code is measured per square centimeter. Document the Mediskin quantity used and retain product or supply records that support the units billed.

Does Q4135 include the application work or interpretation?

Q4135 identifies the product supply, while the application procedure represents the clinical service. CMS classifies Q4135 as technical-component-only, with interpretation covered by a separate code.

How does the global-period rule affect Q4135?

Q4135 is an add-on code and must be reported with a primary procedure. CMS pays it 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.
