Request a Redetermination

The first level of appeal is carried out by the affiliated contractor/MAC.

• Time limit to initiate = 120 days from date of receipt of the initial determination notice
• Time limit to complete the review = 60 days
• Amount in controversy = no minimum amount

Redeterminations may be submitted electronically or in writing.

Requests for redetermination of nonassigned claims must include a completed Appointment of Representative Form (CMS-1696) or a written statement from the beneficiary giving authorization for you to submit a request on his/her behalf.

Submit Your Redetermination

RECOMMENDED - Use NGSConnex

You can submit your redetermination requests using our free, secure Internet portal, NGSConnex. Use the step-by-step instructions in the NGSConnex User Guide. 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.
