Claim Resubmission/Rebilling
Part B CGS Medical Review has noted an increase in resubmitting/rebilling claims that have been denied during the TPE review. Continuously rebilling/resubmitting claims to Medicare is generally not allowed and can lead to payment issues. Rebilling/resubmitting claims that have already been paid or denied without a valid reason may lead to the provider being referred to Unified Program Integrity Contractor (UPIC) for further investigation. Please refer to the below resources regarding correcting errors and appealing initial claim denials.
Clerical error reopening
Clerical error reopenings allows providers to correct minor errors or omissions.

Redetermination
A redetermination is a written request, for a first level appeal, to review a claim when you are dissatisfied with the original claim determination. The request must be received within 120 days from the date of receipt of the notice of initial determination. The redetermination is an independent process to re-evaluate the claim. Requests for redeterminations may not be filed via fax.
