About Q4159: Affinity wound matrix by area
Q4159 reports Affinity, a placental tissue wound product, by square centimeter when supplied with a separately reported wound-graft application procedure.
Q4159 identifies Affinity, a placental tissue-derived wound product used as a covering in wound care. It may be used in settings such as hospital outpatient departments and wound clinics, with application performed by clinicians treating wounds, including surgeons, podiatrists, and other wound-care practitioners. The product code identifies the material, not the procedure that places it on the wound.
Report Q4159 with the primary skin-substitute application procedure, such as the appropriate code from the 15271–15278 family, selected by wound site and treated area. Units are based on the product’s square-centimeter measure; the record should identify Affinity and support the quantity reported with the wound and application details. CMS designates Q4159 as an add-on code, payable only with a primary procedure and within that procedure’s global period. CMS also classifies it as technical-component-only, with interpretation represented by a separate code.

Q4159 billing questions
Does Q4159 report the Affinity product or its application?
It identifies the Affinity wound product. Report the appropriate skin-substitute application procedure separately for placement.
Which application procedure is reported with Q4159?
Choose the applicable code from the 15271–15278 family based on the wound site and treated area. Q4159 must be reported with a primary procedure.
How are Q4159 units determined?
The code is measured per square centimeter. Document the Affinity product and the quantity supporting the units billed.
Can Q4159 be billed by itself?
No. CMS designates it as an add-on code that is billed with a primary procedure and paid within that procedure’s global period.
Does Q4159 include interpretation?
No. CMS classifies Q4159 as technical-component-only; interpretation is represented by a separate code.
Can Q4159 be used for another wound product measured by area?
No. Q4159 identifies Affinity specifically. Use the HCPCS code matching the product actually supplied, even when another product is also measured per square centimeter.
