About Q4178: FlowerAmnioPatch wound product

Reports the per-square-centimeter amount of FlowerAmnioPatch used with a primary wound procedure, such as application of a skin substitute graft.

FlowerAmnioPatch is an amniotic tissue product applied to a wound as part of wound management. Clinicians may use this type of product for chronic or hard-to-heal wounds, including lower-extremity ulcers. Wound-care physicians, surgeons, and other qualified practitioners typically apply it in an office or outpatient setting. Q4178 identifies the product quantity, not the wound assessment or the application service itself.

Report the number of square centimeters represented by the product used, supported by documentation of the product and treated wound area. Submit Q4178 with the primary procedure; CMS treats it as an add-on and pays it within that procedure’s global period. CMS classifies the code as technical-component-only, with interpretation covered by a separate code. The product code is distinct from the application code, so documentation should identify both the graft application service and the FlowerAmnioPatch quantity.

Q4178 billing questions

How is Q4178 different from Q4177?

Q4178 identifies FlowerAmnioPatch by square centimeter. Q4177 identifies FlowerAmnioFlo in 0.1 cc units, so select the code matching the product and its stated unit.

Can Q4178 be billed by itself?

No. CMS designates it as an add-on code, so it is reported with a primary procedure and paid within that procedure’s global period.

Is the wound application included in Q4178?

Q4178 identifies the FlowerAmnioPatch product quantity. Report the applicable primary wound procedure for the application service.

What quantity should the claim show?

Use the number of square centimeters represented by the product used. The record should support the product identity and treated wound area.

Does Q4178 include interpretation?

CMS classifies Q4178 as technical-component-only; 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
