Wound care supply
About Q4258: Enverse wound graft supply
Q4258 reports Enverse supplied for wound coverage, with units based on square centimeters and billing paired with the applicable primary procedure.
Q4258 identifies Enverse supplied for wound coverage and measures the product in square centimeters. It represents the named product rather than the clinician’s wound assessment or application work. Wound-care clinicians and surgeons may furnish it when applying a wound graft or similar skin substitute to a prepared wound bed; the specific product on the claim must be Enverse.
Report Q4258 with the primary procedure for the associated application, using square-centimeter units supported by the product and wound records. Documentation should identify Enverse, the treated site, the quantity used, and the application procedure. CMS treats Q4258 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period. CMS also classifies it as technical-component-only; a separate code covers interpretation.
CMS billing rules for Q4258
- Global period
- Add-on code: billed only together with a primary procedure and paid within that procedure's global period.

Q4258 billing questions
What should be reported with Q4258?
Report the applicable primary procedure for the wound graft application. Q4258 identifies the Enverse product and is not a stand-alone application service.
How are units counted?
The descriptor measures Enverse per square centimeter. Keep records that support the quantity reported and identify the product used.
Can Q4258 be billed by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure and is paid within that procedure’s global period.
Does Q4258 include interpretation?
No. CMS classifies Q4258 as technical-component-only, with interpretation covered by a separate code.
How is Q4258 distinguished from other wound graft product codes?
Use Q4258 only when the product furnished is Enverse. Codes such as Q4257 and Q4259 identify different named products, even when the products are measured per square centimeter.
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.
