About Q4373: Membrane Wrap LT wound graft
Q4373 reports Membrane Wrap LT by square centimeter when this specific wound-covering product is supplied for application with a primary wound-treatment procedure.
Q4373 identifies the Membrane Wrap LT wound-covering product, reported by the square centimeter supplied for application to a wound. It represents the product, not the clinician’s wound-bed preparation or placement work. A wound-care practitioner may use it in an outpatient office or hospital setting to cover a prepared wound, such as a chronic ulcer. The product name in the clinical and supply records should support choosing Q4373 rather than a code for a different membrane or skin substitute.
Report the product quantity in square-centimeter units with the applicable primary wound-treatment procedure. Documentation should identify the product, treated site, wound dimensions or area, and quantity applied. CMS classifies Q4373 as an add-on paid within the primary procedure’s global period, so it is not paid as a stand-alone service. It is technical-component-only; a separate code covers interpretation. Report the practitioner’s placement work under the appropriate application service, not as part of this product code.

Q4373 billing questions
Can Q4373 be billed by itself?
No. CMS classifies it as an add-on that must be billed with a primary procedure and is paid within that procedure’s global period.
How are units determined?
Report the product quantity in square centimeters. Documentation should connect the quantity to the treated wound and the amount applied.
Does Q4373 include the clinician’s application work?
No. Q4373 identifies the Membrane Wrap LT product; report the applicable wound-treatment or application service separately.
Does this code include interpretation?
No. CMS identifies Q4373 as technical-component-only, with interpretation covered by a separate code.
What documentation supports reporting Q4373?
Record the Membrane Wrap LT product identity, treated site, wound area, and quantity applied. The records should distinguish it from other membrane or skin-substitute products.
