In short

Pet plans can deny claims for things the plan does not cover.
Ask the insurer in writing for the reason and the policy words.
If it still seems wrong, complain to your state insurance department.

What this means

Pet plans differ a lot. A denial can be allowed if the plan does not cover the problem. The Texas Department of Insurance says pre-existing conditions are rarely covered [1]. A basic plan may cover only accidents, while other plans also cover illness [2]. Some plans also limit coverage for conditions a breed may inherit [3].

Even so, an insurer should explain the denial. In Washington, a denial must be in writing. It must also name the policy part the insurer used [4]. The sources do not give a pet denial rule for every state.

If you think the denial is wrong, ask for the reason in writing and for the policy words it used. If you still disagree, you can complain to your state insurance department. A department cannot make a company pay unless not paying breaks a law or your policy terms [5].

Your next step

Write to your insurer. Ask for the reason for the denial and the exact policy words. Send your vet records. If you still disagree, file a complaint with your state insurance department. The sources give no deadline for this step.

Check it yourself

Your policy's exclusions and waiting period sections show if the condition counts as pre-existing or inherited. Your vet's records help too. The sources do not say how your state treats pet claim denials. They do not say how your insurer defines "pre-existing" either: "Don't know yet".
