What Q4248 covers
Q4248 represents Dermacyte, an amniotic membrane allograft supplied by the square centimeter for wound care. A wound-care clinician, podiatrist, or surgeon may use the product on a prepared wound bed, including for a chronic ulcer such as a diabetic foot or venous leg ulcer. The product is reported separately from the work of applying it; the application procedure is selected for the wound site and treated area.
Report units that reflect the square centimeters of Dermacyte represented by the claim, and document the product, wound site, quantity used, and associated primary procedure. CMS classifies Q4248 as an add-on code: it must be billed with a primary procedure, and its payment falls within that procedure's global period. It is a technical-component-only code; a separate code covers interpretation, so Q4248 does not represent that professional service.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose
- Q4238Derm-MaxxPer square centimeter
- Q4238 identifies Derm-Maxx, not Dermacyte. Select the product code that matches the material actually supplied rather than choosing by unit of measure.
- Q4247Amniotext patchPer square centimeter
- Q4247 identifies an Amniotext patch product. Q4248 is specific to Dermacyte; the square-centimeter basis does not make the products interchangeable.
- Q4249AmniplyPer square centimeter
- Q4249 identifies Amniply. Use Q4248 only when the product supplied is Dermacyte.
Q4248 billing questions
Can Q4248 be billed by itself?
No. CMS identifies Q4248 as an add-on code that must be billed with a primary procedure.
How should units be reported?
Q4248 is measured per square centimeter. Document the Dermacyte quantity represented by the units on the claim.
Is the wound application included in Q4248?
Q4248 represents the Dermacyte product, not the application work. Report the appropriate primary application procedure with it.
Does Q4248 include professional interpretation?
No. CMS classifies it as technical-component-only and indicates that a separate code covers interpretation.
What documentation supports Q4248?
Record the product identity, wound site, square-centimeter quantity, and the associated primary 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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
