What Q4300 covers

Q4300 identifies the Acesso TL product supplied for wound coverage, measured by square centimeter. Wound-care clinicians may use it when treating an appropriate wound with a skin-substitute product; the associated application procedure reflects the clinician’s work placing the material. The claim should distinguish the Acesso TL product from other wound products and identify the wound and treatment performed.

Report Q4300 only with a primary procedure, such as the applicable skin-substitute application code selected for the wound’s site and treated area. Units represent the documented square centimeters furnished. Keep the product record, amount used, wound measurements, and application details to support the reported units and pairing. CMS identifies Q4300 as a technical-component-only code, with interpretation covered by a separate code. Payment for this add-on falls within the primary procedure’s global period.

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.

Q4300 billing questions

Can Q4300 be reported by itself?

No. CMS identifies Q4300 as an add-on that must be billed with a primary procedure, such as the appropriate skin-substitute application code.

How are units determined?

The descriptor is per square centimeter. Document the amount of Acesso TL furnished and the wound area treated to support the units reported.

How does Q4300 differ from Q4311?

Both descriptors identify a product billed per square centimeter, but Q4300 names Acesso TL and Q4311 names Acesso. Report the code matching the specific product furnished.

Does Q4300 include interpretation?

No. CMS classifies Q4300 as technical-component-only; 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.
