Pet Insurance Basics: Reading a Policy in Ten Minutes

Three numbers and two exclusions tell you most of what you need to know about a pet insurance plan.

Pet insurance works differently from human health insurance. You usually pay the vet, file a claim and get reimbursed. To compare plans quickly, focus on these parts of the policy.

The three numbers

  • Deductible: what you pay each year before the plan pays anything.
  • Reimbursement rate: the percentage of a covered bill the plan pays after the deductible, commonly 70%, 80% or 90%.
  • Annual limit: the most the plan will pay in a policy year. Some plans are unlimited.

Changing any of these changes the premium. A higher deductible or lower reimbursement rate lowers the monthly cost but leaves you with more of each bill.

The two exclusions to read first

Pre-existing conditions: anything that showed symptoms before coverage started is typically excluded. Some plans reconsider curable conditions after a symptom-free period.

Waiting periods: accidents may be covered within days, illnesses after a couple of weeks, and some orthopedic conditions later still.

Accident-only vs. accident and illness

Accident-only plans are cheap but skip illnesses like infections, allergies and cancer, which drive many large vet bills. Accident-and-illness plans are the most common choice. Wellness add-ons for routine care help with budgeting but often pay back about what they cost.

Buy early

Premiums rise as pets age, and every new diagnosis before enrollment becomes a potential exclusion.
