What Q4284 covers

Q4284 identifies Dermabind SL supplied for application to a wound as a skin-substitute wound product. Wound-care clinicians may use it in settings such as outpatient wound clinics, physician offices, and hospital outpatient departments. The code represents the product quantity, not the clinical work of preparing the wound or applying the product; those services are represented by the appropriate primary procedure.

Report units based on the square centimeters of Dermabind SL supplied, and document the product variant, wound site, treated area, and associated application procedure. This is an add-on code: it must be billed with a primary procedure, and payment falls within that procedure's global period. CMS classifies Q4284 as technical-component-only, with a separate code covering interpretation.

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.

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.
