How can I appeal a claim that was denied?

If you do not agree with a denial, your recourse is to submit an appeal of denial to IUSupport@wexinc.com. All appeals must be in writing. The appeal will need to include the reason for your appeal and any additional documentation that is needed to support your appeal.
 
You may also mail the appeal to WEX Inc.:
