| Document | What it establishes | What to check |
|---|---|---|
| Itemized veterinary invoice | The pet, treatment date and individual charges. | A card-payment slip alone may not identify the services billed. |
| Proof of payment | What you paid the clinic, where reimbursement requires it. | Retain receipts for deposits and later balances without counting either twice. |
| Medical record | The veterinarian’s history, examination findings, assessment and treatment. | A short receipt is not a substitute for clinical notes; identify any previous clinic holding relevant records. |
| Submission confirmation | What you sent and when the insurer received it. | Keep the claim number and a copy of the uploaded files, including later additions. |
Other insurers can request further history. Ask which specific document is missing rather than repeatedly uploading the same invoice. For follow-up visits, ask whether to add them to an existing claim or submit a new one under the insurer’s instructions.
