New coding guidance: More than 150 new codes have daily use limits, but they aren’t without appeal

Why This Topic Matters

The update can affect claim acceptance, denial management, and appeal workflows for services and supplies with newly assigned daily limits. It matters to revenue cycle and coding teams because payer edits may differ from guidance in the CPT manual and because some denials may be appealable when medical necessity can be documented.
