The reimbursement rate is the amount of money, as a percentage, that your policy will send you to cover your pet’s medical expenses. Let’s continue the example we used above with a vet bill totalling $3,000. After the $500 deductible is met, you are left with a $2,500 vet bill. A policy with an 80% reimbursement rate would cover $2,000 of the remaining $2,500 vet bill. With MetLife Pet Insurance, you can get reimbursed for up to 100% of the cost of covered expenses, depending on the policy you choose.
