What Q4150 covers
Q4150 identifies Allowrap DS or Dry, a dehydrated amniotic membrane product used as a biologic covering over a prepared wound bed. Wound-care physicians, podiatrists, and surgeons may use it in outpatient or hospital settings for selected wounds, including chronic nonhealing ulcers. The code represents the product, not the clinical work of preparing the wound or applying the material; those services are reported through the applicable procedure code.
Report Q4150 only with a qualifying primary wound-application procedure, such as the appropriate code from the skin-substitute application family. Count the product in square-centimeter units and document the specific product, amount used, wound site and treated area, and the associated application procedure. CMS classifies Q4150 as an add-on and places its payment within the primary procedure’s global period. It is technical-component-only; a separately coded professional interpretation is represented by a separate code.

Q4150 billing questions
Can Q4150 be billed by itself?
No. CMS identifies it as an add-on, so report it with the qualifying primary wound-application procedure.
How should units be counted?
The descriptor is based on one square centimeter. Document the quantity of Allowrap supplied for the treated wound area.
Which code reports the application?
Use the primary skin-substitute application procedure appropriate to the wound location and treated area; Q4150 reports the Allowrap product itself.
What does the technical-component classification mean?
CMS classifies Q4150 as technical-component-only. Any separately coded professional interpretation is represented by a separate code.
What documentation supports Q4150?
Record that Allowrap DS or Dry was used, the wound site and treated area, the product quantity, and the paired application procedure.
