What Q4110 covers
Q4110 identifies PriMatrix, a fetal bovine dermal matrix supplied for wound coverage, including treatment of chronic ulcers and other wounds. Wound-care clinicians and surgeons may use it in outpatient wound clinics, hospital outpatient departments, or other settings where a skin substitute is applied. The code represents the product, not the work of preparing the wound or applying the matrix.
Report the quantity in square centimeters and document the product and wound area treated. Pair Q4110 with the primary skin-substitute application procedure that matches the treatment site and wound area; for example, 15271 may apply to an eligible trunk, arm, or leg wound within its area threshold. CMS classifies Q4110 as an add-on, so it is billed only with a primary procedure and paid within that procedure’s global period. CMS also identifies it as technical-component-only, with interpretation covered by a separate code.

Q4110 billing questions
Does Q4110 report the PriMatrix application?
No. Q4110 reports the PriMatrix product by square centimeter. Report the applicable skin-substitute application procedure separately as the primary service.
What should support the number of units?
Document that PriMatrix was used and the square-centimeter quantity represented by the product supplied for the wound treatment.
Can Q4110 be billed by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure, and payment falls within that procedure’s global period.
Is Q4110 the same as Q4102 or Q4104?
No. Q4110 identifies PriMatrix; Q4102 and Q4104 identify different wound-matrix products. Report the code for the product actually used.
How does the technical-component designation affect reporting?
CMS classifies Q4110 as technical-component-only and indicates that a separate code covers interpretation. Q4110 itself identifies the PriMatrix product.
