About Q4101: Apligraf skin substitute supply

Q4101 reports Apligraf supplied for wound treatment, measured by area and billed with the procedure used to apply the product.

Q4101 represents Apligraf, a living skin substitute used to support healing of chronic wounds such as venous leg ulcers and diabetic foot ulcers. Wound-care physicians, surgeons, podiatrists, and other clinicians may apply it in outpatient wound clinics or other settings where these wounds are treated. The code represents the product, not the clinician’s application service.

Report the quantity based on the square centimeters of Apligraf supplied, and document the wound, product used, and amount applied. Q4101 is an add-on code: report it only with a primary application procedure, and its payment falls within that procedure’s global period. CMS assigns no physician work RVUs and assigns practice-expense RVUs. CMS classifies Q4101 as technical-component-only; a separate code covers interpretation.

Q4101 billing questions

Does Q4101 report the Apligraf application?

No. Q4101 reports the Apligraf product; report the applicable skin-substitute application procedure separately as the primary service.

What is the unit of service?

Q4101 is measured per square centimeter. Document the wound area treated and the amount of Apligraf used.

Can Q4101 be billed by itself?

No. It is an add-on code and must be reported with a primary procedure, such as the applicable skin-substitute application code.

How does the global-period rule affect payment?

Q4101 is paid within the primary procedure’s global period. Its payment is tied to that procedure rather than treated as a separate standalone service.

Does Q4101 include an interpretation?

No. CMS classifies Q4101 as technical-component-only, and a separate code covers interpretation.

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.
