What Q4312 covers

Q4312 identifies the Acesso AC product used as a skin substitute or wound-covering material. It is reported by the clinician or facility furnishing the product during wound care, such as treatment of a chronic ulcer. The product code is distinct from the procedure that prepares the wound and applies the material; that procedure is selected according to the treated site and wound area.

Report the quantity in square centimeters and retain documentation identifying Acesso AC, the amount furnished, and the treated wound. CMS classifies Q4312 as an add-on code: submit it with a primary procedure, and its payment falls within that procedure’s global period. CMS also classifies it as technical-component-only, with a separate code covering interpretation. For example, the primary application procedure may be 15271 for an eligible trunk, arm, or leg site, or 15275 for an eligible head, face, neck, hand, foot, or genital site.

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.

Q4312 billing questions

What does one unit of Q4312 represent?

The code is reported by square centimeter. Document the Acesso AC product and the quantity furnished for the treated wound.

Can Q4312 be billed by itself?

No. CMS identifies it as an add-on code, so report it with a primary procedure for the wound service.

Which application procedure is paired with Q4312?

Choose the primary application procedure based on the treated site and wound area. Examples include 15271 for eligible trunk, arm, or leg sites and 15275 for eligible head, face, neck, hand, foot, or genital sites.

How is Q4312 different from Q4311?

Both are product-specific codes reported by square centimeter, but Q4312 identifies Acesso AC and Q4311 identifies Acesso. Do not select between them based only on the similar names.

Does Q4312 include interpretation?

No. CMS classifies Q4312 as technical-component-only and indicates that 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.
