Submit Your Redetermination Request

RECOMMENDED - Use NGSConnex

You can submit your redetermination requests using our free, secure Internet portal, NGSConnex. Follow the step-by-step instructions in the NGSConnex User Guide to submit your redetermination. If supporting documentation needs to be included with the redetermination, follow the instructions to add the documentation.

Note: There are no file size limitations to the attachments that can be submitted in NGSConnex; the only file types not accepted are: .xml, .log and .cfg.

Note: If there are multiple services on the same claim in question (same ICN), you only need to submit a single redetermination/reopening request. You should not submit multiple redetermination/reopening requests for the same claim.
