Pet Insurance in Ohio: What the 2025 Law Guarantees You

Ohio is one of four states where a pet insurance policy now has to meet statutory minimums, and it combines that with premiums that run below the national average. That’s a better starting position than most states offer. The law is narrower than people assume, though, and the parts it leaves alone are the parts that still decide what you pay.

Ohio quotes trend below the national average

NAPHIA’s 2026 State of the Industry report, which covers 2025, puts the average US accident-and-illness premium at $836 a year for a dog, about $70 a month, and $435 a year for a cat, about $36 a month. The statistics page has the full breakdown, including the double-digit increase in 2025.

Ohio holds 2.6% of US insured pets but only 2.2% of US written premium. A state whose premium share is below its pet share has a lower-than-average premium per insured pet, so per NAPHIA’s distribution data, average premiums in Ohio run below the national average. NAPHIA gives no state dollar figure, and we won’t invent one.

Below average doesn’t mean uniform. Insurers set rates by ZIP code, and a quote in Columbus, Cleveland, or Cincinnati tends to land higher than one for the same pet in a rural county, because the vets there charge more.

What Ohio Revised Code Chapter 3970 gives you

Ohio enacted the NAIC Pet Insurance Model Act as Senate Bill 175 of the 135th General Assembly, now Ohio Revised Code 3970.01 to 3970.08, effective January 22, 2025. As of October 2026 it’s one of four such laws in the country, alongside California, Florida, and Pennsylvania, per the NAIC’s Summer 2026 tracker.

For a buyer, the chapter does five concrete things. Under section 3970.05, the waiting period for illnesses, and for orthopedic conditions that don’t result from an accident, can’t exceed 30 days. There is no waiting period for accidents at all, so an injury in the first week of the policy isn’t blocked by a wait. The policy may waive the waiting period after a veterinary medical examination. The insurer, not you, bears the burden of proving that a pre-existing condition exclusion applies to a claim. And section 3970.01 defines “orthopedic condition” in the statute itself: conditions of bones, skeletal muscle, cartilage, tendons, ligaments, and joints, including hip and elbow dysplasia, IVDD, patellar luxation, and ruptured cruciate ligaments, while excluding cancer and metabolic, hemopoietic, and autoimmune diseases from that definition.

That last point matters more than it sounds. Without a statutory definition, what counts as orthopedic is whatever the policy form says. In Ohio the list is fixed in statute, and the wait on it is capped at 30 days. Pet insurance waiting periods explains how long those windows typically run elsewhere, and cruciate ligament surgery shows why the orthopedic one is the wait that bites.

What the Ohio law leaves alone

Chapter 3970 does not cap premiums, and it does not cap renewal increases. If your renewal jumps by double digits, that’s legal, and it’s consistent with the 11.5% national rise NAPHIA recorded for dogs in 2025. The law also does not limit the types of exclusions an insurer may use; the chapter says that explicitly. So hereditary conditions, bilateral conditions, exam fees, prescription food, and behavioral care can all still be excluded in Ohio if the policy says so. What pet insurance doesn’t cover lists the usual suspects.

If an insurer ignores the waiting-period cap or denies a claim as pre-existing without evidence, the complaint goes to the Ohio Department of Insurance. Keep the denial letter and the vet records; under 3970.05 it’s the insurer that has to show the exclusion applies.

Tick season in Ohio and the clause it tests

Tick-borne disease is concentrated in the Northeast, the upper Midwest, and parts of the Southeast, and Ohio sits at the junction of the first two. Lyme disease, anaplasmosis, and ehrlichiosis are illness claims, so accident-only cover does nothing for them, and the 30-day illness cap is a real advantage: a dog enrolled in April is covered for a tick-borne infection picked up in June. Chronic cases, where joint pain or kidney involvement follow the infection, are where the policy’s chronic-condition wording and annual limit come into play.

Preventive tick and heartworm products are routine care, outside the core policy, and only a wellness add-on reimburses them. Does pet insurance cover vaccinations covers whether that add-on is worth the money.

Columbus referrals and the annual limit

Complex Ohio cases often end up at The Ohio State University College of Veterinary Medicine in Columbus, an AVMA-accredited teaching hospital with specialty and emergency services. Referral medicine means advanced imaging, surgery, oncology, and intensive care, and those are the bills that run past a low annual limit. The Ohio law doesn’t touch limits; you pick the cap, and the cap decides how much of a Columbus referral you carry yourself. Does pet insurance cover cancer is a useful illustration of how quickly a capped policy runs dry.

The three settings every Ohio policy still has

The statute fixed the waiting-period problem; it left the pricing dials to you. The deductible, the reimbursement percentage, and the annual limit set both your premium and your share of any bill, and the reimbursement calculator shows the trade-off on a real figure. Pre-existing conditions are still excluded in Ohio, even if the burden of proof now sits with the insurer, so enrolling while the record is clean is the single biggest lever. And if you’re moving a pet from another insurer, switching still makes everything already on file pre-existing with the new company, law or no law.
