Does pet insurance cover pre-existing conditions?
No pet insurer covers pre-existing conditions. Every insurer we review excludes anything that showed signs before your policy started or during its waiting period, even if the condition was never formally diagnosed: a vet note saying your dog was limping can be enough to exclude cruciate claims for life. The one real nuance is curable conditions: some insurers, Embrace most explicitly, will cover a curable issue again after a long symptom-free period, while chronic conditions like diabetes or ongoing allergies stay excluded permanently.
What counts as pre-existing
Insurers define pre-existing broadly: any condition that showed clinical signs before enrollment or during the waiting period, whether or not a vet ever wrote down a diagnosis. This is the single biggest reason claims get denied, and the single best argument for insuring a pet the week you get them rather than after the first symptom appears.
Bilateral rules catch people out. Healthy Paws states that if one knee’s cruciate ligament was hurt before enrollment or during the wait, the other knee’s cruciate is excluded too. Spot treats both knees as linked the same way. A past injury on one side can remove coverage for the other side permanently.
The curable-condition exception
Some insurers split pre-existing conditions into curable and chronic. Embrace is the clearest example: a curable condition like an old ear infection or a one-off bout of vomiting can be re-evaluated and covered again after 12 consecutive symptom-free, treatment-free months. Chronic conditions stay excluded for good. Most other insurers in our lineup, including Healthy Paws, Lemonade, Trupanion, Spot, Pets Best, Figo and Fetch, apply the standard exclusion with no such re-coverage path spelled out.
What to do if your pet already has a condition
A new policy still protects you against everything new, just never against the excluded condition or anything related to it. If your pet already has a chronic diagnosis, compare the premium against what the policy can realistically pay, since the most likely claims are already locked out. Either way, get your pet’s vet records before enrolling so you know exactly what an insurer will point to later.
