What Q4143 covers
Q4143 identifies Repriza, a tissue product used in wound care. Wound-care clinicians and surgeons may apply it to a wound as part of treatment; the product code represents the material rather than the clinician’s evaluation or the wound-application work. The primary procedure code describes the application service, with the appropriate procedure selected for the wound site and treated area.
Report Q4143 with the required primary procedure, using units that match the amount of product applied and the code’s area-based measure. Documentation should identify Repriza, the wound treated, the area covered, and the quantity used; product records can support the material reported. CMS treats Q4143 as an add-on paid within the primary procedure’s global period, so it is not reported alone. CMS classifies it as technical-component-only, with interpretation covered by a separate code. Its CMS valuation has no physician work component and includes practice expense.

Q4143 billing questions
When should Q4143 be selected instead of another wound-product code?
Use Q4143 when the product applied is Repriza. Similar wound products have their own HCPCS codes, so select by the product actually used rather than by wound type alone.
Can Q4143 be billed by itself?
No. CMS identifies it as an add-on that must be billed with a primary procedure and is paid within that procedure’s global period.
What documentation supports the units?
Record the product name, wound site, treated area, and amount of Repriza applied. Report units according to the code’s area-based measure and the quantity documented.
Does Q4143 include the wound-application service?
Q4143 represents the Repriza product. Report the applicable wound-application procedure separately as the primary procedure.
How does the component rule affect reporting?
CMS classifies Q4143 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.
