Does Pet Insurance Cover Pre-Existing Conditions?

Updated October 13, 2026 · 2 min read · 3 sources

Short answer

Generally no. A pre-existing condition, meaning anything your pet showed signs of before the policy started or during the waiting period, is excluded. Many insurers will cover a "curable" condition again (such as a bladder infection) once your pet has gone 180 days to 12 months without symptoms or treatment, but chronic conditions like diabetes, allergies or cancer usually stay excluded.

Pre-existing conditions are the single biggest source of claim denials and surprises in pet insurance. Understanding the rules before you enroll can save you a lot of money and frustration.

What counts as a pre-existing condition

Pet Insurance Quotes defines it as any condition your pet showed symptoms of before you bought the policy. Conditions that appear during the waiting period also count. It doesn't matter whether a vet had formally diagnosed it: if the records show signs, insurers can treat it as pre-existing. Insurers review your pet's medical records when you make a claim.

Curable vs. incurable conditions

Type Examples Can it be covered later?
Curable Bladder infections, gastrointestinal upsets, respiratory infections Often yes, after a symptom- and treatment-free period
Incurable / chronic Allergies, cancer, diabetes, heart disease, thyroid disease, orthopedic injuries Usually excluded permanently
Bilateral Cruciate ligament tears, hip dysplasia, glaucoma If one side was affected first, the other side is often excluded too

Symptom-free periods by insurer

Pet Insurance Quotes (updated July 2025) lists these waiting rules for covering a cured condition again:

Insurer Symptom- and treatment-free period
Embrace 12 months
Fetch 12 months from plan purchase
Figo At least 12 months
Lemonade At least 12 months
Prudent Pet 365 days (one-time curable conditions)
ASPCA 180 days (excludes knee and ligament conditions)
Pets Best 180 days (excludes knee and ligament conditions)
Pumpkin 180 days (excludes knee and ligament conditions)
Spot 180 days (excludes knee and ligament conditions)
Healthy Paws No set timeframe; covers acute conditions that fully resolve

Rules can change and may vary by state, so confirm in the current policy. Insurify also notes that AKC Pet Insurance covers pre-existing conditions after a one-year waiting period.

Can you get pet insurance if your pet already has a condition?

Yes. You can buy a policy, and it will cover new, unrelated accidents and illnesses. The existing condition (and related conditions) will be excluded. The Nevada Division of Insurance notes that a vet exam may be required to certify your pet's health.

Switching insurers with a pre-existing condition

Be careful. Anything treated under your current policy will be a pre-existing condition to a new insurer. Switching can mean losing coverage for an ongoing problem. Compare carefully before cancelling.

How to avoid pre-existing condition problems

  1. Enroll as early as possible, ideally when your pet is a puppy or kitten.
  2. Get a vet exam right before enrolling so the records show a healthy baseline.
  3. Read the waiting periods; don't let a gap in coverage create a new exclusion.
  4. Keep coverage continuous; a lapse can make earlier conditions pre-existing.
  5. Ask how bilateral conditions are handled if your breed is prone to knee or hip problems.
