The reimbursement rate is the portion of a covered veterinary bill your insurer pays back to you. Most US pet insurance runs on a reimbursement model: you pay the vet in full, submit the bill, and the insurer sends money back according to your policy's math.
If your policy carries a 90% reimbursement rate, the insurer covers 90% of the eligible costs and the remaining 10% - the co-insurance - stays with you. Insurers typically let you choose the rate when you buy the policy, and that choice, together with your deductible and annual limit, defines what a claim actually pays.
