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.

Q4183 billing questions

Does Q4183 describe applying the graft or the material?

It identifies SurgiGraft material by square centimeter. Report the primary procedure for the graft application separately.

Can Q4183 be billed by itself?

No. CMS identifies it as an add-on that must be reported with a primary procedure and is paid within that procedure’s global period.

How should units be determined?

Use the square-centimeter quantity for the SurgiGraft material. Documentation should support the amount used and the wound area treated.

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?

No. CMS identifies this as a technical-component-only code; 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.
