What Q4152 covers
Q4152 represents the Dermapure biologic dermal matrix supplied for wound care; it is the product code, not the service of preparing the wound or placing the material. Clinicians may use a dermal matrix in treating wounds such as chronic ulcers. The treating physician or other qualified practitioner typically documents the wound site and dimensions and performs or oversees the application in an outpatient or facility setting.
Report the measured square centimeters of Dermapure supplied, supported by the product record and documentation of the wound area treated. Bill Q4152 only with a primary procedure; CMS treats it as an add-on and includes its payment within that procedure's global period. CMS classifies the code as technical-component-only, with interpretation covered by a separate code. Report the applicable skin-substitute application procedure separately; its selection depends on the wound site and treated area.

Q4152 billing questions
Does Q4152 report Dermapure placement?
No. Q4152 reports the Dermapure product; report the applicable skin-substitute application procedure separately.
Can Q4152 be billed by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure, and its payment falls within that procedure's global period.
How are units determined?
The code is measured per square centimeter. Document the amount of Dermapure supplied and the wound area treated to support the units reported.
Which application code should accompany Q4152?
Select the skin-substitute application procedure according to the treated body site and area. For example, 15271 is for application to the trunk, arms, or legs within its stated area range.
Does Q4152 include professional interpretation?
No. CMS identifies Q4152 as technical-component-only; a separate code covers interpretation.
