About Q4137: AmnioExcel or BioDExcel wound matrix
Reports AmnioExcel or BioDExcel amniotic tissue matrix by area when supplied for wound coverage with a separately coded application procedure.
Q4137 represents AmnioExcel or BioDExcel, an amniotic tissue matrix supplied for placement over a wound. It may be used in outpatient wound care, including treatment of chronic ulcers such as diabetic foot or venous leg ulcers. The clinician assesses the wound and prepares and applies the material; the product code accounts for the matrix, not the work of applying it.
Report the quantity in square centimeters of product used and pair Q4137 with the applicable primary wound-application procedure. The record should identify the product, treated wound, amount used, and application procedure. CMS classifies Q4137 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period. CMS also identifies it as technical-component-only, with interpretation covered by a separate code.

Q4137 billing questions
How is Q4137 different from a wound-application code?
Q4137 reports the AmnioExcel or BioDExcel material by area. Report the applicable primary procedure separately for the clinician’s wound preparation and application service.
What quantity should be reported?
Report the square centimeters of product used. Document the amount applied to the wound and the product identity.
Can Q4137 be billed by itself?
No. CMS classifies it as an add-on code, so it must be reported with a primary procedure and is paid within that procedure’s global period.
Does Q4137 include interpretation?
No. CMS identifies Q4137 as technical-component-only; a separate code covers interpretation.
How should the record support Q4137?
Document the wound treated, the AmnioExcel or BioDExcel product used, the area applied, and the associated primary application procedure.
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.
