What Q4108 covers

Q4108 identifies Integra Matrix, a wound-care matrix product used on a prepared wound bed. It may be encountered in wound-care services and surgical treatment of wounds; wound-care clinicians and surgeons typically document the wound treated and the product used. It is distinct from other Integra products, including bilayer matrix wound dressing, dermal regeneration template, and flowable wound matrix.

CMS classifies Q4108 as an add-on code, so report it only with a primary procedure; its payment falls within that procedure’s global period. The code is technical-component-only, with interpretation covered by a separate code. Documentation should identify Integra Matrix, the treated wound site, the primary procedure, and the quantity applied. Use the product’s square-centimeter unit when reporting the quantity, and ensure the primary procedure matches the service performed and wound location.

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.

Q4108 billing questions

How is Q4108 different from Q4104 or Q4105?

Q4108 identifies Integra Matrix. Q4104 identifies Integra Bilayer Matrix Wound Dressing, while Q4105 identifies Integra Dermal Regeneration Template or Omnigraft; report the product actually used.

Can Q4108 be billed by itself?

No. CMS identifies it as an add-on code, so it must be reported with a primary procedure and is paid within that procedure’s global period.

What should the record support?

Document the Integra Matrix product, wound site, primary procedure, and quantity applied. The reported units should reflect the product quantity represented in square centimeters.

Does Q4108 include interpretation?

CMS classifies Q4108 as technical-component-only; a separate code covers interpretation. The record and claim should distinguish the technical service from any separately coded interpretation.

Which application procedure may be reported with Q4108?

A skin-substitute application procedure may serve as the primary procedure, with the specific code selected according to the treated site and service. Q4108 is not reported without that primary procedure.

Where these rates come from

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.
