What Q4435 covers

Q4435 identifies Renati membrane furnished for wound coverage, measured by the product area in square centimeters. It represents the product, not wound preparation or the clinician’s application service. In outpatient wound care, podiatry, or surgical settings, a treating clinician may use the membrane as part of care for a chronic or difficult-to-heal skin wound. The product and the procedure used to apply it are distinct claim elements.

Report the units supported by the square-centimeter amount of product furnished, and document the product, wound, treated area, and related application procedure. CMS classifies Q4435 as an add-on code: it must be billed with a primary procedure and is paid within that procedure’s global period. It is technical-component-only; a separate code covers interpretation. Do not submit Q4435 as a standalone product line.

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.

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.
