What does pet insurance cover?
A standard accident and illness pet insurance policy covers unexpected vet bills: injuries like broken bones and swallowed objects, plus illnesses like infections, cancer, and hereditary conditions that first show symptoms after enrollment. Every policy excludes pre-existing conditions, and routine care like checkups and vaccines is only covered if you buy a wellness add-on. Coverage is reimbursement-based: you pay the vet, then claim the money back minus your deductible, at your chosen reimbursement rate, up to an annual limit.
What is typically covered
Accident and illness policies, the standard product from every insurer we review, cover new injuries and new illnesses. That means emergency surgery, hospitalization, diagnostics like X-rays and MRIs, prescription medications, and treatment for conditions that first appear after your waiting periods end. Cancer treatment, one of the most expensive claim categories, is covered by all of our reviewed plans.
Hereditary and congenital conditions are where plans genuinely differ. Some insurers cover them in full provided no symptoms appeared before enrollment. Others exclude anything your breed is known for, which for a French Bulldog or a Dachshund removes most of the reason you were insuring. We flag this on every breed page.
What is typically excluded
Pre-existing conditions are excluded by every insurer we review. Anything that showed signs before your policy started or during the waiting period, even if never formally diagnosed, will not be covered. Some insurers, Embrace most clearly, will cover a curable condition again after a symptom-free period, but chronic conditions stay excluded for good.
Routine and preventive care, like annual exams, vaccines, and flea prevention, is excluded from base policies everywhere. Some insurers sell a wellness add-on that reimburses a fixed allowance toward it. Dental illness is excluded or thin on most plans; Fetch includes dental disease in its base policy, while Lemonade covers it only through an optional add-on. Behavioral treatment, breeding costs, and cosmetic procedures are also commonly excluded.
The mechanics that shape real coverage
Three numbers decide what a policy actually pays. The annual limit caps total payouts per year, from $2,500 on the low end to unlimited on plans like Healthy Paws and Trupanion. The deductible is what you pay first. The reimbursement rate, usually 70, 80, or 90 percent, is the share of the remaining bill the insurer returns. A cheap plan configured with a low limit and low reimbursement rate can leave you holding most of a big bill.
