What Q4365 covers

Q4365 identifies Amnio Buried Dermal Membrane supplied for wound coverage, measured by the product’s surface area. Wound-care clinicians and surgeons may use the membrane during treatment of a wound in an outpatient wound clinic, physician office, or hospital outpatient department. The code represents the product, not the work of applying it to the wound.

Report the quantity in square centimeters and retain documentation identifying the product and the area used. The CMS file classifies Q4365 as an add-on: report it only with a primary procedure, and its payment falls within that procedure’s global period. CMS also classifies it as technical-component-only, with interpretation represented by a separate code. The claim should therefore identify the paired primary procedure and distinguish the product quantity from the wound-application service.

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.

How to choose

15271Skin substitute graft
15271 reports the wound-application procedure for qualifying sites and wound area; Q4365 reports the Amnio Buried Dermal Membrane product used with a primary procedure.
15275Skin substitute
15275 is the application procedure for qualifying head, neck, hand, foot, or genital sites. Q4365 identifies the product and is measured by square centimeter.
Q4363Amniotic membrane
Q4363 identifies a different Amnio Buried membrane product. Select the HCPCS code matching the product supplied rather than choosing between them by wound size.

Q4365 billing questions

Is Q4365 the wound application procedure?

No. Q4365 reports the Amnio Buried Dermal Membrane product by square centimeter. Report it with the appropriate primary wound procedure.

What should support the reported units?

Document the product used and the square centimeters supplied or applied. The code is measured by product area, not by the number of wounds.

Can Q4365 be billed by itself?

No. CMS identifies it as an add-on code that must be billed with a primary procedure.

Does Q4365 include interpretation?

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

How does Q4365 differ from Q4363?

Both are per-square-centimeter wound products, but they identify different products. Use Q4365 for Amnio Buried Dermal Membrane, not the product identified by Q4363.

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.
