What Q4104 covers
Q4104 identifies Integra Bilayer Wound Matrix (BMWD), a collagen-based wound matrix with a protective outer layer used to cover partial- and full-thickness wounds. Typical settings include wound-care clinics, outpatient surgery, and hospital-based wound treatment. Clinicians may use it for chronic ulcers, surgical wounds, traumatic wounds, or burns; the treating clinician applies the product to the prepared wound.
Report the product with the primary wound or skin-substitute application procedure, not as a stand-alone service. CMS classifies Q4104 as an add-on paid within the primary procedure’s global period. The code represents the product rather than the clinician’s application work; document the product used and the wound area treated, and report units according to the applicable HCPCS descriptor. CMS also identifies Q4104 as technical-component-only, with interpretation covered by a separate code when applicable.
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.

Q4104 billing questions
Can Q4104 be reported by itself?
No. CMS identifies it as an add-on that must be billed with a primary procedure; payment falls within that procedure’s global period.
Which application procedure is commonly paired with Q4104?
Pair the product with the applicable skin-substitute application procedure, such as the 15271–15278 family. Select the application code based on the wound site and area treated.
How should units be supported?
Document the BMWD product used and the wound area treated. Report units according to the applicable HCPCS descriptor and the documented quantity.
Does Q4104 include the clinician’s application work?
No. Q4104 identifies the product. The primary procedure represents the application service, and CMS places Q4104 within that procedure’s global period.
What does the technical-component-only designation mean?
CMS identifies Q4104 as technical-component-only and states that interpretation is covered by a separate code when applicable.
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.
