Q: What are the reason code ranges for claims when they have denied?
A: For claims that have been reviewed by the medical review department and denied, the reason code will start with a "5". If your claim was denied through the fiscal intermediary shared system (FISS) the reason code will start with a "7", which is a non-medical denial.
