Insurance Appeal Guides
AppealFlow editorial publishes free guides on US health insurance denials, appeal deadlines, payer processes, and medical billing disputes. Each article explains your rights under ERISA, ACA, or Medicare rules where they apply and links to a matching free appeal generator when one exists.
Health insurance denials arrive with jargon: medical necessity edits, prior authorization failures, step therapy requirements, and remark codes on your remittance advice. Our guides translate those terms into plain steps you can take before an appeal deadline passes. We focus on US health coverage only, not auto, home, or life insurance.
Every guide is written by AppealFlow editorial and reviewed against primary sources such as Healthcare.gov appeal rules, ERISA claims procedure regulations, and Medicare.gov when Medicare topics apply. When a specialized generator fits your denial type, the article points you to the matching tool so you can draft a letter faster.
New articles cover GLP-1 and weight-loss medication appeals, MRI and imaging denials, dental and orthodontic claims, surprise emergency bills under the No Surprises Act, and general workflows like internal appeal versus external review. Use the list below to find a guide that matches your denial reason code or benefit issue.
How Do I Find a Guide for My Denial Type?
Start with the denial reason on your EOB or adverse benefit determination letter. Search the article list for your drug name, procedure, or code (for example CO-50 medical necessity or a prior authorization denial). Denial code pages at /denial-codes explain common CARC codes and link to longer how-to guides.
Which Tools Match These Guides?
The free appeal generator handles general claim denials. The tools hub lists specialized generators for GLP-1 medications, MRI denials, prior authorization, prescription formulary exceptions, dental claims, and No Surprises Act disputes. Pick the tool that matches the article you read.
What If My Appeal Deadline Is Soon?
Check your EOB for the internal appeal deadline first. ERISA employer plans often allow at least 180 days for a first-level appeal, while ACA marketplace notices may use shorter windows. File before the printed date even if you are still collecting records; many plans let you supplement the file after the initial submission.
