What Q4190 covers

Q4190 identifies Artacent AC, a biologic wound-covering product, with the billing unit based on square centimeters. It is used when this specific product is supplied for wound coverage, such as during treatment of a chronic wound or ulcer. The clinician applying the material may be a physician or another qualified practitioner working in an office, wound clinic, or hospital setting.

Report the quantity in square centimeters and pair the product line with the applicable primary wound-application procedure. Documentation should identify Artacent AC, the treated wound and site, and the area of product used. CMS classifies Q4190 as an add-on code: it is billed with a primary procedure and paid within that procedure’s global period. It is also a technical-component-only code; interpretation is represented by a separate code when applicable.

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.

Q4190 billing questions

When should Q4190 be selected instead of Q4189?

Both identify Artacent AC, but Q4190 is measured per square centimeter and Q4189 per milligram. Use the code and unit that match the product quantity documented.

Can Q4190 be billed by itself?

No. CMS classifies it as an add-on code, so it must be reported with the applicable primary procedure.

How is the Q4190 quantity determined?

Report the square-centimeter quantity of Artacent AC used for the wound. The record should support the product and area reported.

Does Q4190 include the wound-application procedure?

No. Q4190 identifies the Artacent AC product; report the applicable primary procedure for applying the material separately.

Does Q4190 include a professional interpretation?

No. CMS classifies Q4190 as technical-component-only, with interpretation covered by a separate code when applicable.

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.
