What Q4117 covers

Q4117 identifies Hyalomatrix, a wound-covering matrix made with hyaluronic acid and a protective outer layer. Clinicians may use it as a temporary covering in the treatment of acute or chronic wounds, including burns and hard-to-heal ulcers. The product is furnished in settings where a clinician performs a skin-substitute application, such as an outpatient wound clinic or hospital department.

Report Q4117 only with the primary procedure, such as the applicable skin-substitute application service; it is an add-on code and is paid within that procedure’s global period. Select the product code that matches the material actually furnished, and report units using the product’s square-centimeter measure. Records should identify Hyalomatrix, the wound treated, the area and amount applied, and the related application procedure. CMS classifies Q4117 as technical-component-only; interpretation is represented by a separate code when separately reportable.

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.

Q4117 billing questions

Can Q4117 be billed without a wound application procedure?

No. CMS identifies Q4117 as an add-on code that must be reported with a primary procedure. For wound treatment, pair it with the applicable skin-substitute application service.

Does Q4117 include the clinician’s work to apply the matrix?

Q4117 identifies the Hyalomatrix product. Report the applicable application procedure separately when performed; the product code is paid within that primary procedure’s global period.

How are Q4117 units determined?

The code is measured per square centimeter. Document the area and amount of Hyalomatrix used and report units under the applicable product-coding instructions.

What documentation supports Q4117?

The record should identify Hyalomatrix as the product furnished, the treated wound, the area covered, the quantity used, and the related application procedure.

Does Q4117 have a professional or technical component?

CMS designates Q4117 as technical-component-only, with interpretation covered by a separate code. The product line should identify the Hyalomatrix furnished.

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.
