About Q4140: BioD-Fence tissue matrix by area
Reports BioD-Fence tissue matrix by treated area when clinicians apply the product to a wound or soft-tissue site with a primary procedure.
Q4140 identifies BioD-Fence, a placental-derived tissue matrix supplied for application to a prepared wound or soft-tissue site. Clinicians may use it as a protective covering on wounds such as chronic ulcers or operative defects. The product code represents the material, not the work of preparing the site or applying the matrix; those services are represented by the related procedure code when separately reportable.
Report the product by the documented area used, with one unit representing one square centimeter. The record should identify BioD-Fence, the treated site, the area applied, and the associated primary procedure. CMS classifies Q4140 as an add-on code: submit it only with a primary procedure, and payment falls within that procedure’s global period. CMS also classifies it as technical-component-only, with a separate code covering interpretation.

Q4140 billing questions
Can Q4140 be billed by itself?
No. CMS identifies Q4140 as an add-on code, so it must be reported with a primary procedure.
How are units determined?
Report one unit for each square centimeter of BioD-Fence used. Document the treated area and the amount applied.
Does Q4140 include the application procedure?
No. Q4140 reports the BioD-Fence product; the associated wound or skin-substitute application procedure is reported separately when appropriate.
How does Q4140 differ from Q4138?
Q4140 identifies BioD-Fence, while Q4138 identifies the DryFlex form of BioD-Fence. Select the code that matches the product form used.
What does the technical-component classification mean?
CMS classifies Q4140 as technical-component-only, with interpretation covered by a separate code.
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.
