What Q4310 covers

Q4310 identifies Procenta as the item reported under this HCPCS Level II code. The code’s stated measure is 100 milligrams, so unit reporting is based on the amount of Procenta rather than surface area. One unit represents 100 mg furnished; report units based on the total amount furnished. Q4310 is designated technical-component-only, and a separate code covers interpretation.

Medicare classifies Q4310 as carrier priced (status C) under the physician fee schedule. CMS publishes no national payment amount; the Medicare Administrative Contractor sets payment for each claim. The HCPCS pricing method likewise assigns claim pricing to the Medicare contractor under the physician fee schedule. Coverage is left to the contractor’s judgment. Thus, claim-level contractor pricing, rather than a published national amount, governs payment. The code was added effective April 1, 2024.

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.

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.
