The full picture
Every US pet insurance carrier excludes pre-existing conditions. The distinction that matters: 'curable' vs. 'incurable.' Curable conditions (UTI, hot spot, kennel cough, GI upset) become covered again at Embrace, ASPCA, MetLife, and Nationwide after 6–12 months symptom-free. Incurable conditions (diabetes, allergies, cancer, CCL/ACL tear, heart disease) are permanently excluded. Bilateral exclusion clauses — found at Trupanion, Healthy Paws, Spot — also exclude the OTHER leg/joint/organ if one side was previously affected. Run our /tools/pre-existing checker before assuming a past diagnosis disqualifies you.

Frequently asked questions

- No — universally excluded. The only exception: curable conditions (UTI, ear infection, kennel cough) become covered after a symptom-free waiting period at some carriers.
- What if my pet had pre-existing conditions issues before I enrolled?▾
- Pre-existing pre-existing conditions issues are excluded by every US carrier. Embrace, ASPCA, MetLife, and Nationwide can re-cover curable conditions after 6–12 months symptom-free — Trupanion, Healthy Paws, and Spot generally cannot.
- Which carriers offer the strongest pre-existing conditions coverage?▾
- Based on our 2026 carrier audit: Embrace, ASPCA, Pets Best, and Trupanion consistently lead. See our /report-cards for the full scoring.
- How do I appeal if my claim was denied?▾
- Use our /appeal builder to generate an insurer-specific appeal letter in 5 minutes. Most appeals succeed because the original denial cited the wrong policy clause.
