Carrier rules — Trupanion
Some carriers' rules need a paragraph of nuance. Trupanion's needs one sentence: its binding form has no cure pathway — no number of symptom-free days, no continuous-coverage anniversary, after which a pre-existing condition becomes coverable. What is pre-existing on day one is excluded on day one thousand. That is not a criticism; it is a product design, and Trupanion does other things owners value (its appeal window, at 180 days, is the most generous in this set). But it makes the switch arithmetic brutally simple in both directions.
| Rule | As published in the form |
|---|---|
| Cure rule | No cure pathway — pre-existing stays excluded for the life of the policy |
| Knee / bilateral | UNVERIFIED |
| Chronic conditions | Never re-open — the cure pathway only reaches conditions that can be cured |
| Orthopedic wait (new policy) | Orthopedic waiting periods run 0–12 months across the 22 audited carriers; Trupanion's figure is not yet verified from its form. |
| How it pays | A percentage of the covered bill (after deductible) |
| Exam fee | Never paid — the exam fee is excluded on every plan |
| Appeal window after a denial | 180 days (carrier's own procedure, compiled Oct 20, 2026) |

Variance, printed not smoothed: The binding form has no cure pathway: a condition that is pre-existing to a Trupanion policy stays excluded. Trupanion also never reimburses the exam fee.
Every condition in your pet's record is excluded permanently from the day the policy starts — not for 180 days, not for 365: permanently. For a pet with a clean record that may be a fair trade. For a pet whose conditions are the reason you're shopping, the checker will show you Trupanion's row as a wall of "excluded for the life of the policy" — because that is what the form computes to.
The reverse case is where owners get hurt twice. Conditions that arose while Trupanion covered your pet are covered conditions at Trupanion — and pre-existing conditions everywhere else, starting new clocks (180 days, 365 days) at the destination. Owners leave Trupanion over price and discover the policy they left was the only one that would ever pay for the condition it had been covering. Run the destination's dates before you cancel anything: the Switch-Check.
