Free health insurance appeal tools
AppealFlow free tools draft health insurance appeal and dispute letters for common denials. Use the GLP-1 generator for Wegovy, Zepbound, and Ozempic prior auth; the imaging tool for denied MRI, CT, or PET scans; the dental generator for crowns and implants; the step-therapy and prescription tools for PBM formulary rejects; the prior authorization and medical necessity generators for UM denials; and the No Surprises Act tool for many surprise ER and facility bills. When no specialty tool fits, open the general appeal studio to upload your EOB or enter denial details manually. Every tool is free, requires no login, and exports a letter you review before filing. Gather your denial letter, EOB, itemized bill when relevant, and clinical records, then submit through the portal or address on your notice before the internal appeal deadline. Internal appeal rights for many private plans come from ERISA or ACA Section 2719; Medicare and Medicaid use separate appeal paths and forms.

How do I pick the right appeal generator?
Match the tool to the denial reason on your EOB or denial letter. GLP-1 and step-therapy tools cover pharmacy prior auth and fail-first rules. The imaging tool covers MRI, CT, and PET scan denials. The No Surprises Act tool covers many surprise out-of-network bills. The dental generator handles LEAT downgrades and missing X-ray denials. When the denial does not fit a specialty tool, use the general appeal studio. Every generator below is free and links to a dedicated page with steps, document checklists, and FAQs for that denial type.
