What Q4148 covers

Q4148 identifies Neox, Neox RT, or Clarix Cord placental tissue used as a biologic wound covering, commonly for chronic wounds such as diabetic foot or venous leg ulcers. Physicians, podiatrists, and surgeons may apply the product in an outpatient wound clinic or hospital setting after preparing the wound. Q4148 reports the product, not the clinician’s wound-preparation or application work.

Select this code for the named product and report units according to the square centimeters supplied. Documentation should identify the product, the treated wound and its measured area, and the amount applied. CMS classifies Q4148 as an add-on code: report it with the applicable primary wound-application procedure, and its payment falls within that procedure’s global period. CMS also classifies it as technical-component-only; a separate code represents interpretation.

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.

Q4148 billing questions

When is Q4148 reported with a wound-application code?

Report Q4148 with the primary procedure used to apply the tissue, such as the appropriate skin-substitute application code for the wound site and size. Q4148 is an add-on and is not reported by itself.

How should the units be determined?

Use the square centimeters of the named product supplied. Record the wound dimensions and the amount of product applied to support the reported units.

Does Q4148 include wound preparation and application?

No. Q4148 identifies the product; the primary procedure represents the application service.

What product documentation supports Q4148?

Document whether the product was Neox, Neox RT, or Clarix Cord, along with the treated wound, its measured area, and the quantity used.

Does Q4148 include interpretation?

No. CMS classifies Q4148 as technical-component-only, with interpretation represented by a separate code.

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.
