How DenialHelp fits in
You typically need to file an internal appeal with your insurer before Illinois will accept an external review request. DenialHelp drafts that internal appeal in five minutes from your denial letter — physician-ready, cited to medical evidence, and formatted for clean transmission to your insurer. If the internal appeal still loses, you can then file with the Illinois Department of Insurance for external review.
