How to File a Pet Insurance Claim: Step-by-Step

Before submitting a claim, gather three things: the itemized veterinary invoice (showing each line-item charge), the medical records or treatment notes from the visit, and the pet's diagnosis or procedure codes if available. Most providers require the invoice to include the clinic name, date of service, and a breakdown of charges — lump-sum invoices are frequently flagged for additional documentation.

Most major providers now offer three submission methods: mobile app (photo upload of the invoice), online portal (upload scanned documents), or email. A few providers still accept mailed claims but this is increasingly rare. Mobile app submissions are typically the fastest — several providers report that app-submitted claims are processed 2–3 days faster than emailed claims on average.

Claims must generally be submitted within 90 days of the invoice date, though some providers allow up to 270 days. Filing promptly is beneficial: longer delays increase the chance of missing documentation or provider follow-up requests.

Claim processing times vary by provider. Trupanion processes the majority of claims within 24 hours through its direct-pay system with participating vets. Lemonade uses AI-assisted processing and reports median claim times under 48 hours for straightforward claims. Most other providers (Embrace, Spot, Healthy Paws, ASPCA) process claims within 5–14 business days. Complex claims requiring additional medical records or specialist review can take 30+ days.

The most frequent denial reasons include: pre-existing conditions (the condition existed before the policy start date or during the waiting period), treatment during the waiting period, billing for excluded services (cosmetic procedures, breeding costs, preventive care on an accident-illness-only plan), and insufficient documentation. If a claim is denied, most providers allow an appeal process — submitting additional medical records or a letter from the treating veterinarian can sometimes reverse the decision.
