Keep the denial notice, correspondence from the insurance carrier, workplace injury reports, claim forms, medical records, written work restrictions, and documents showing time missed from work. Photographs of injuries and the injury location, as well as witness information, emails, text messages, work schedules, and pay records, might also provide helpful context.
It can also help to create a timeline showing when the injury occurred, when it was reported, when medical treatment began, and when the carrier issued its decision. Review your medical records for accuracy. If a record contains an error, ask the medical provider about its process for requesting a correction or adding clarification.
