What Q4363 covers

Q4363 identifies the hydrated form of an Amniobur amniotic membrane product used as a covering for a wound. A wound-care clinician, surgeon, or podiatrist may place it over a prepared wound in an outpatient wound clinic, office, or surgical setting. The code represents the product, not the wound assessment or the act of applying it. For example, it may be used during care of a chronic ulcer when a clinician selects an amniotic membrane covering.

Report the number of square centimeters represented by the product, supported by documentation of the product name, wound site, and area supplied or used. Q4363 is an add-on code and must be billed with a primary procedure; CMS pays it within that procedure's global period. It is technical-component-only, with a separate code covering interpretation. The primary application code is selected for the wound location and treated area.

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.

Q4363 billing questions

Can Q4363 be billed by itself?

No. CMS identifies Q4363 as an add-on code, so report it only with a primary procedure.

How are units counted?

The code is measured per square centimeter. Document the product area supplied or used and report the corresponding square-centimeter units.

Which application procedure is reported with Q4363?

Pair it with the primary wound-graft application procedure appropriate to the wound's anatomical site and treated area, such as a code in the 15271–15278 family.

What documentation supports Q4363?

Record the Amniobur product form, wound location, and square-centimeter area supplied or used, along with the primary procedure.

Does Q4363 include interpretation?

No. CMS classifies it 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 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.
