Top 7 reasons pet insurance claims get denied

Understanding why claims are denied is the first step to avoiding it. Here are the most common reasons based on complaint data from AFCA and industry reports.

1. Pre-existing condition exclusion. This is the number one reason. The insurer found a record of the same or related symptoms in your pet's veterinary history before the policy started or during the waiting period. Even a vet's note saying "suspect" or "rule out" can be enough to trigger a pre-existing exclusion.

2. Waiting period not served. Illness claims have a standard 30-day waiting period. If you submit a claim on day 25 — even if symptoms only appeared that day — the insurer will deny it. Cruciate ligament claims have a 6-month waiting period with most insurers and this is the most common trap.

3. Annual limit reached. Your policy has an annual benefit limit, say $12,000. If you have already claimed $11,500 this year and your pet needs a $2,000 surgery, the insurer will only pay $500. The rest is your responsibility. You do not need to hit the limit exactly — anything over it is automatically denied.

4. Sub-limit cap triggered. Even if you are under your annual limit, specific treatments have their own caps. Dental illness might be capped at $500 per year. Cancer treatment at $3,000. Physiotherapy at $500. If your claim exceeds the sub-limit, the excess is denied regardless of your remaining annual limit.

5. Policy exclusion for that condition. Some policies specifically exclude certain conditions. Bilateral condition clauses exclude the second-side of a paired issue (like hip dysplasia in the second hip). Breed-specific exclusions exist for conditions common to certain breeds. Behavioural issues and alternative therapies are commonly excluded in budget policies.

6. Incorrect or incomplete paperwork. The claim form must be signed by both you and the vet. The invoice must show the date of service, itemised treatments, and the vet's registration number. Missing any of these and the claim will be returned, which can push it past time limits.

7. Lapsed policy. If your payment failed and the policy lapsed before the treatment date, you are effectively uninsured regardless of when you reinstate it. This is particularly brutal because you might not realise the payment failed until the claim is denied.

How to appeal a denied claim step by step

Step 1: Request a detailed written explanation. Your insurer must provide the specific PDS clause they used to deny the claim. Do not accept a generic explanation like "pre-existing condition." Ask for the exact wording, the date of the veterinary record they are relying on, and the specific policy clause.

Step 2: Gather your veterinary records. Get the complete medical history from your vet. Look for anything that contradicts the insurer's reasoning. If the insurer says the condition existed before the policy started, find the vet notes that show when symptoms first appeared. Sometimes the insurer uses a different record than the treating vet.

Step 3: Write a formal appeal letter. Address it to the insurer's internal dispute resolution team. Reference the policy clause, the insurer's denial reason, and explain why you believe the claim should be paid. Include supporting documents. Keep a copy of everything sent.

Step 4: Escalate to AFCA if needed. If the internal appeal is rejected or you hear nothing within 45 days, lodge a complaint with the Australian Financial Complaints Authority. AFCA is free, independent, and can award compensation up to $1,050,000. You can lodge online at afca.org.au.

How to prevent claims from being denied

Read the full PDS before you buy, not after. Know your sub-limits, waiting periods, and exclusions before you need to claim. Keep a copy of your policy schedule somewhere accessible. Make auto-payments never miss a premium. Submit claims promptly with all required paperwork. And most importantly, understand the difference between "covered" and "covered up to a limit" — that difference is where most denials live.

The AFCA process explained

AFCA is an independent ombudsman service that resolves disputes between consumers and financial services providers, including pet insurers. The process is free for consumers. You must first give your insurer 45 days to resolve the complaint internally. If they do not resolve it to your satisfaction, AFCA will investigate. They can request documents from both sides, make a preliminary assessment, and issue a determination that is binding on the insurer (but not on you — you can still go to court if you disagree with AFCA's decision).

In 2025, AFCA received over 1,200 complaints about pet insurance, with the most common issues being claim denials based on pre-existing conditions and waiting period disputes. About 40% of complaints were resolved in favour of the consumer.
