About Q4136: EzDerm wound matrix supply
Q4136 represents EzDerm, a porcine-derived wound matrix reported for the product used with a primary wound procedure, such as skin substitute application.
Q4136 identifies EzDerm, a porcine-derived acellular dermal matrix supplied as a wound covering. It may be used in wound care, including selected partial-thickness burns and skin-graft donor sites. The code represents the product, not the clinician’s wound preparation or application service. Wound-care clinicians and surgeons may use the matrix in an office, outpatient department, or other surgical setting, depending on the patient’s treatment plan.
Report Q4136 only with a primary procedure; CMS treats it as an add-on and includes its payment within that procedure’s global period. The product is measured per square centimeter, so documentation should identify EzDerm and the amount used, along with the wound site and the associated procedure. CMS classifies Q4136 as technical-component-only; a separate code covers interpretation. The reported product quantity should be supported by the operative or treatment record.

Q4136 billing questions
Is Q4136 the wound application procedure?
No. Q4136 represents the EzDerm product. Report the applicable primary procedure for the wound treatment separately.
Can Q4136 be billed by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure.
How should the amount of EzDerm be documented?
Record the amount used in square centimeters, identify the wound site, and link the product to the primary procedure in the treatment or operative record.
Does Q4136 include interpretation?
No. CMS classifies Q4136 as technical-component-only, with interpretation covered by a separate code.
How does Q4136 differ from Q4137?
Q4136 identifies EzDerm. Q4137 identifies AmnioExcel or Biodexcel, so choose the product code that matches the material supplied.
