How this works
Pick your carrier and the reason cited in the denial. The generator builds a cite-paragraph-by-cite-paragraph appeal letter and an attachments checklist. Runs in your browser — your inputs are never uploaded.
Open the generator →Each carrier has its own appeal address, window, and escalation path — Embrace gives you 14 days, Pets Best 60, Trupanion 6 months, Figo 90, Lemonade routes to a 3-employee panel. Read your carrier's exact rules before drafting.
Find my carrier →If the carrier-side appeal fails, the state insurance commissioner reviews claim-handling practices. Pet insurance is regulated as P&C — every state has a complaint pathway. We surface the form for each one.
