What Q4183 covers
Q4183 represents SurgiGraft material measured by the square centimeter for use in wound care. It is reported for the product used with a primary procedure to apply a skin substitute graft, such as treatment of a wound in a wound-care clinic or other setting where the graft application is performed. The code identifies the material, not the clinician’s work of applying it.
Report the quantity in square centimeters and document the product used, the wound site and area treated, and the associated primary application procedure. CMS classifies Q4183 as an add-on: it is billed only with a primary procedure and paid within that procedure’s global period. Its PFS valuation contains practice expense but no physician work or malpractice value. CMS identifies it as technical-component-only, with interpretation covered by a separate code.
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.

What documentation supports Q4183?
Record the SurgiGraft product, quantity, wound site and treated area, and the primary procedure performed to apply the graft.
Does Q4183 include interpretation?
