The process for appealing claim determinations remains the same. If you disagree with the determinations made by the Medical Review department, your next level of appeal is a redetermination. A redetermination is an independent re-examination of a claim. If you wish to appeal, this must be done within 120 days from the date of the demand letter. Please note that First Coast takes into consideration all appeals overturned prior to initiating a subsequent TPE round of review.
