About Q4305: American Amnion AC Tri-Layer wound allograft
Reports the per-square-centimeter supply of American Amnion AC Tri-Layer allograft used as a wound covering with a separately coded application procedure.
Q4305 identifies the American Amnion AC Tri-Layer product supplied for wound coverage. It is a human amniotic membrane allograft used in wound care, including treatment of nonhealing wounds. A physician, podiatrist, or other qualified clinician may apply it in an office or outpatient setting as part of wound management. The related application service is reported separately; Q4305 represents the product rather than the clinician’s application work.
Report the quantity in square centimeters and document the product used, the wound treated, and the amount applied. Pair Q4305 with the applicable primary wound-graft application procedure. CMS classifies this as an add-on code, payable only with a primary procedure and within that procedure’s global period. CMS also identifies it as technical-component-only, with interpretation covered by a separate code.

Q4305 billing questions
Is Q4305 the application procedure?
No. Q4305 reports the American Amnion AC Tri-Layer product by square centimeter; report the appropriate wound-graft application procedure separately.
Which application code should accompany Q4305?
Select the primary application code based on the treated body site and the applicable wound-area criteria. For example, 15271 is used for qualifying trunk, arm, or leg sites, while 15275 applies to qualifying head, face, neck, hand, foot, or genital sites.
How should the quantity be documented?
Record the product identity and the square-centimeter quantity represented by the product used, along with the treated wound and its dimensions.
Can Q4305 be billed by itself?
No. CMS identifies Q4305 as an add-on code that must be reported with a primary procedure and is paid within that procedure’s global period.
How does Q4305 differ from Q4306?
Both are per-square-centimeter product codes, but Q4305 identifies American Amnion AC Tri-Layer. Use the code matching the product actually supplied.
Does Q4305 include interpretation?
CMS classifies Q4305 as technical-component-only; a separate code covers interpretation.
