About Q4329: Singlay wound graft supply
Q4329 reports Singlay wound-graft product by square centimeter when it is used with a primary wound procedure for graft application.
Q4329 identifies the Singlay wound-graft product supplied for wound coverage; it does not describe the clinician’s application service. Wound-care clinicians and surgeons may use the product during treatment of wounds in settings such as outpatient wound clinics and hospital outpatient departments. The specific product used, rather than wound size alone, determines whether Q4329 is the appropriate product code.
Report Q4329 only with a primary procedure, such as the applicable skin-substitute application code selected for the wound site and treated area. The quantity is reported by square centimeter, so documentation should identify Singlay and support the amount used, including the product dimensions and treated wound. CMS classifies Q4329 as technical-component-only, with interpretation covered by a separate code. Payment for this add-on falls within the primary procedure’s global period.
CMS billing rules for Q4329

Q4329 billing questions
When should Q4329 be chosen over another wound-graft product code?
Use Q4329 when the product applied is Singlay. A different named product, such as Most or Total, has its own product code.
Can Q4329 be reported by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure.
Which application code is reported with Q4329?
Use the skin-substitute application code that matches the treated body site and area, such as 15271 for qualifying wounds on the trunk, arms, or legs.
How is the quantity for Q4329 counted?
The code is measured per square centimeter. Record the Singlay product dimensions and the amount used so the reported quantity is supported.
Is interpretation included in Q4329?
CMS classifies Q4329 as technical-component-only and indicates that a separate code covers interpretation.
