What Q4409 covers

Q4409 identifies the Amniomatrix F3X wound product supplied for use in wound coverage, with the reported quantity measured in square centimeters. It represents the product, not the clinician’s work to prepare or apply it. Wound care clinicians may use this type of product during treatment of wounds such as diabetic foot or venous leg ulcers when the product is selected for the patient’s wound. The clinical record should identify the product and the amount furnished.

Report Q4409 only with a primary procedure; CMS treats it as an add-on code and pays it within that procedure’s global period. Select the primary application service based on the wound site and procedure performed, and report product units supported by the documented square-centimeter quantity. CMS classifies Q4409 as technical-component-only, with interpretation covered by a separate code. Its CMS valuation has no physician work component; the reported service is the product supply.

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.

Can Q4409 be billed by itself?

No. CMS identifies Q4409 as an add-on code that must be reported with a primary procedure and paid within that procedure’s global period.

How is the quantity reported?

The code is measured per square centimeter. Document the Amniomatrix F3X product and the square-centimeter quantity furnished.

Does Q4409 include the clinician’s application work?

No. Q4409 identifies the product supply; report the appropriate primary application procedure for the wound service performed.

How does Q4409 differ from Q4411?

Q4409 identifies Amniomatrix F3X, while Q4411 identifies Amniomatrix F4X. Use the code matching the product furnished.

No. CMS classifies Q4409 as technical-component-only and specifies that a separate code covers interpretation.

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.
