Pre-existing condition

What the denial letter says

"This claim involves a condition that was pre-existing under your policy. A pre-existing condition is one that occurred or showed clinical signs prior to the effective date of coverage or during any applicable waiting period."

How to contest it

1. 1

   Get the full vet record for the 12 months before your policy effective date and read it line-by-line. If the symptoms the carrier is calling 'pre-existing' don't appear there, you have a documentary basis to dispute.

2. 2

   Identify the date of first symptoms in the records. If that date is AFTER your policy effective date (and after the relevant waiting period), the condition is not pre-existing under most carriers' definitions.

3. 3

   Cite the policy section's exact wording back. Most carriers' definitions hinge on 'clinical signs' — a vague mention in a wellness exam is not usually 'clinical signs'. Your vet may need to write a clarifying note distinguishing routine-exam findings from a clinical diagnosis.

4. 4

   If a condition is bilateral (e.g., both knees), the cross-laterality may be cited — see the bilateral-condition pillar.

5. 5

   If the carrier waived a 'curable' pre-existing condition after a symptom-free interval (some carriers do this for non-chronic issues), check whether your case meets that exception in your specific policy.
