What Q4440 covers

Q4440 identifies the Curamatrix wound product by the square centimeter. It represents the product used on a wound bed, not the clinician’s work to prepare or treat the wound. Wound-care clinicians and surgeons may use the matrix during an office, outpatient, or facility-based wound procedure; the clinical record should identify the treated wound and the product used.

Report Q4440 only with the primary procedure for the wound treatment. CMS treats this as an add-on code, paid within the primary procedure’s global period. Report units based on the square centimeters represented by the product used, and retain documentation supporting the wound area and product quantity. CMS classifies Q4440 as technical-component-only; a separate code covers interpretation. The record should distinguish Curamatrix from other wound products billed under their own product codes.

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.

How to choose

15271Skin substitute graft
This is a primary wound-treatment procedure code, while Q4440 identifies the Curamatrix product used with a primary procedure.
Q4414Wound matrix
Q4414 identifies Simplicho rather than Curamatrix. Choose the product code matching the material used.
Q4431Pma skin substitute, nos
Q4431 is a nonspecific skin-substitute product code; Q4440 identifies Curamatrix by name.

Q4440 billing questions

How is Q4440 different from another wound-product code?

Q4440 identifies Curamatrix specifically. Select the product code that matches the product actually used, rather than choosing by wound size or appearance alone.

Can Q4440 be billed without a primary procedure?

No. CMS identifies Q4440 as an add-on code that must be billed with a primary procedure and is paid within that procedure’s global period.

How are units determined?

The code is reported per square centimeter. Documentation should support the wound area treated and the quantity of Curamatrix used.

Does Q4440 include the clinician’s wound-treatment work?

No. Q4440 identifies the Curamatrix product; the primary procedure accounts for the wound treatment and application service.

Does Q4440 include interpretation?

No. CMS classifies it as technical-component-only, with interpretation covered 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.
