Summary

Priority Health's system is incorrectly denying drug dosing claims with error code U83 even when providers correctly follow billing guidance by not using JW/JZ modifiers on line 1. The insurance company will automatically reprocess all impacted claims once their system is fixed, requiring no action from providers.

Action Required

Action needed
No action required: Continue following current Provider Manual billing guidance for drug dosing claims. Do not submit inquiries via Prism for U83 denials - Priority Health will automatically reprocess impacted claims once their system update is complete. Monitor for automatic claim corrections.
