Opening
A pet insurance claim follows a reimbursement model: you pay the vet, you file, and the insurer pays you back a share of the eligible bill. That sequence sounds simple, and the paperwork is where it succeeds or fails. The insurer checks the claim against the policy — covered condition, pre-existing status, waiting period, deductible, reimbursement rate and annual limit — and it checks those questions against vet records. This page explains what to file, how reimbursement is calculated, and what to do if a claim is denied.
How a claim works
You pay the full vet bill at the clinic, submit a claim form with the itemised invoice and any requested medical records, and the insurer reviews the claim against the policy terms. It applies your deductible and reimbursement percentage, confirms the amount has not exceeded your annual cap, and issues reimbursement by cheque or direct deposit — to you, not to the vet, in the usual reimbursement model. A small number of plans offer direct payment to vets; if yours does, the sequence differs, and your plan wording governs. No processing time is promised here: times vary by insurer and claim, and your policy or the insurer's confirmation states its own timeframe.
What to do at the vet visit
Ask for an itemised invoice showing diagnosis, treatment and cost, and keep proof of payment — a receipt or bank statement. Ask the vet to record the diagnosis and the date symptoms first appeared clearly, because that date is often the evidence that decides a pre-existing dispute. Keep every visit's records, not only the claim visit's: an insurer may request the full history to test whether a condition predates cover. Photograph or scan documents the same day, and keep originals as well as copies.
How to file
Documents usually needed (general)
Itemised invoice and proof of payment
The itemised vet invoice is the core document: it shows what was done, why, and what it cost. Proof of payment shows you paid it. A summary bill without itemisation, or an invoice without proof of payment, commonly triggers a request for more documents and delays the claim.
Vet medical records
Medical records — commonly called SOAP records — help the insurer identify whether the condition predates cover. On a first claim, many insurers request the pet's full medical history leading up to the incident; on later claims, they may request records only for the condition claimed, or request the full history again. Request complete records from every vet your pet has seen, including any prior clinic: a pre-existing dispute often turns on records from a clinic you did not think to request, and incomplete records can work against you in either direction.
Claim form and policy details
The completed claim form, your policy number and the certificate sections that define the benefit claimed. If the claim involves an accident, include any incident description the form asks for; if it involves illness, include the symptom history as the vet recorded it, not a rewritten version. Accuracy matters more than emphasis: a record that contradicts the claim form is worse than a claim form that is plainly written.
How reimbursement is calculated
In the common educational form: reimbursement = (eligible bill − remaining deductible) × reimbursement percentage, capped at the remaining annual limit. Your owner cost is the bill minus the reimbursement, plus any non-covered charges. Some insurers apply deductible and coinsurance in a different order, and some use per-incident rather than annual deductibles — your own policy's formula governs, and the pet cost calculator on this site lets you test the common form on your own numbers. Check the calculation on your reimbursement notice against your own arithmetic: if it differs, ask the insurer to show its working before you accept it.
If a claim is denied
Most denials trace back to a handful of standard reasons: a pre-existing condition exclusion, a waiting-period exclusion, a condition or treatment the plan excludes (hereditary, elective, routine), a deductible or limit already reached, or missing documentation. Read the denial letter for the exact reason and the exact policy clause it cites. A vague denial letter — one that names no clause and cites no record — is itself worth pushing back on: ask for the specific clause and the specific medical record relied on, in writing.
How to appeal, step by step
ILLUSTRATIVE EXAMPLE (not a policy fact)
A hypothetical owner files a claim for a dog's eligible treatment with a $1,500 itemised bill, a $250 annual deductible with nothing met yet, and 80% reimbursement. The insurer's notice shows $1,000 reimbursed — matching ($1,500 − $250) × 80%. The owner checks the arithmetic, finds it matches, and keeps the notice with the invoice. In a second, hypothetical variation, the same claim is denied as pre-existing, citing a vet note from before enrolment. The owner pulls the full history, finds the note refers to a different, resolved issue, and appeals with the complete records and a clause-by-clause letter. Neither variation promises an outcome: the first shows checking the arithmetic, the second shows the appeal method, and both are governed in a real case by the real policy and real records.
If a claim goes quiet
A quiet claim usually waits for a document: a vet record, an itemised invoice, a proof-of-payment record. Ask the insurer, in writing, what exactly is outstanding, send it, and note the date. Follow up if you receive no acknowledgement within the time your policy or the insurer's confirmation states. Do not file a duplicate claim while the first is open unless the insurer tells you to.
Frequently asked questions
Do I pay the vet first? In the usual reimbursement model, yes. You pay the full bill, then claim it back. Direct-payment plans are the exception, not the rule — check whether yours offers it.
Why does the insurer want my pet's full history? To test pre-existing status and waiting periods. A condition's first appearance date, in vet records, is often the deciding evidence — which is why complete records from every clinic matter.
Can a denied claim be overturned? In general terms, yes, where the denial rests on missing documents or a misreading of the records or wording, and the appeal supplies what was missing or corrects the reading. A denial that correctly applies an exclusion to your facts will not be overturned by argument alone.
