MEDICAL REVIEW: Where can I find more details about the reasons my claims were denied?

You are able to see the reason why your claim was denied several ways. The most in-depth rationale can be found in the FISS DDE on page 04. You can also find your denial reason in NGSConnex, on your Remittance Advice, and at the end of the round on your Results Letter via the denial code column. View the FISS/DDE Provider Online Guide for additional guidance.
