Pet Insurance in Washington: Costs and the 2024 State Law

Washington sits right on the national average, and it’s one of the states where the waiting-period clause is written by the legislature rather than the insurer. Chapter 48.205 RCW has been in force since January 1, 2024. Add three of the largest claims NAPHIA reported for 2025, all paid in Kirkland and Mercer Island, and the state makes a clear case for buying the higher annual limit.

Washington sits at the national average, seventh by insured pets

NAPHIA’s industry data gives the 2025 baseline: $836 a year for a dog on accident-and-illness cover, about $70 a month, and $435 a year for a cat, about $36 a month, up 11.5% and 12.6% in one year. The statistics page tracks the series.

NAPHIA’s 2026 report ranks Washington seventh among states by insured pets, with 3.8% of insured US pets and 3.8% of US written premium. The two shares match at the one decimal NAPHIA prints, so per NAPHIA’s distribution data, average premiums in Washington run about the national average. NAPHIA rounds to one decimal and publishes no Washington dollar figure, so treat the national figures as a starting estimate, not a precise one.

Insurers rate by ZIP code, so a quote in Seattle or its Eastside suburbs tends to come in above the same pet in a rural county east of the mountains. Run your own ZIP through the cost calculator, and read how much pet insurance costs for the settings that move the number.

Chapter 48.205 RCW: what a Washington policy must offer

As of October 2026 the NAIC’s Summer 2026 tracker lists Washington as a model-adoption state. The law is chapter 48.205 RCW, and it took effect on January 1, 2024. What it fixes for a buyer:

• Waiting periods for accidents are prohibited. A waiting period for illnesses or orthopedic conditions not resulting from an accident can’t exceed 30 days, and none applies at renewal.
• The policy must let you waive the wait by completing a medical examination; the insurer may require a licensed veterinarian after purchase, and you pay for the exam unless the policy says the insurer will.
• A 15-day free look: return the policy within 15 days of receiving it and the premium is refunded within 30 days, unless you’ve filed a claim.
• The insurer bears the burden of proving that a pre-existing exclusion applies to the condition you’re claiming for.
• A covered condition can’t be treated as pre-existing at renewal, and no vet exam can be required to renew.
• The insurer must disclose its exclusions, waiting periods, deductibles, coinsurance, and limits, and whether premiums rise with claim history, age, or location.

What the chapter leaves alone matters just as much. RCW 48.205.030 says it doesn’t prohibit or limit the types of exclusions insurers may use, so hereditary, bilateral, and chronic exclusions are still policy choices, and nothing in the chapter caps premiums. The waiting period guide compares Washington’s 30-day ceiling with the forms used elsewhere, and the pre-existing conditions guide explains what a vet-exam waiver can put on the record.

Complaints about an insurer go to the Office of the Insurance Commissioner.

The Kirkland and Mercer Island claims on NAPHIA’s list

NAPHIA’s 2026 report lists the largest claims its members paid across North America in 2025, and three were paid in Washington. On the dog list, $46,700 for kidney disease in a 13-year-old medium mixed-breed dog in Mercer Island. On the cat list, $45,900 for hepatopathy (liver disease) in a 7-year-old mixed medium-hair cat in Kirkland, and $37,400 for trauma in a 4-year-old domestic medium-hair cat, also in Kirkland.

Two of the three are cats, worth a pause when cat cover costs about half the dog figure and the temptation is to insure a cat lightly. Does pet insurance cover kidney disease in dogs and does pet insurance cover liver disease show how the first two run as claims; the trauma case is the ordinary accident claim at its most expensive end.

Rattlesnakes east of the Cascades and Washington’s tick picture

The Washington Department of Fish and Wildlife says the western rattlesnake is common and widespread in eastern Washington, east of the Cascades, and that of the dozen or so snake species in the state it’s the only one capable of a venomous bite. A bite is an accident claim, and because Washington bans accident waiting periods, a bite in the first week of a new policy is covered like one in year three, subject to the deductible, reimbursement rate, and limit. Does pet insurance cover snake bites covers antivenom and the hospital stay.

Ticks are a smaller story than in the Northeast. The Washington State Department of Health reports relatively few tick-borne disease cases each year compared with some other parts of the country, says lone star ticks and Ixodes scapularis aren’t native to Washington, and notes that anaplasmosis has been diagnosed in numerous dogs in the state. So the illness side still has a tick claim to carry, with a wait of at most 30 days under chapter 48.205. Preventives are routine care; does pet insurance cover vaccinations explains when a wellness add-on makes sense.

Pullman’s teaching hospital and the annual limit

Washington State University in Pullman is the state’s AVMA-accredited veterinary college, last evaluated in 2024 with its next review due in 2031, and its Veterinary Teaching Hospital runs a 24-hour emergency service and has been AAHA-accredited since 1983. The cases that make the trip to Pullman are the ones that test the annual limit. Washington’s law doesn’t touch limits; the cap is yours to choose, and the three claims above are the argument for a high one while the pet is young and the premium is low. The reimbursement calculator shows how a large bill splits at different caps.

Where Washington’s law stops and the policy begins

Chapter 48.205 fixes the waiting periods, the free look, the renewal rules, and who has to prove a pre-existing exclusion. Everything else is the national mechanism: you pay the vet, file, and get a percentage of the covered bill back after the deductible; reimbursement explained has the arithmetic. Conditions on the record before enrollment are still excluded, now with the insurer having to prove it, so a short record is still the biggest lever on cover and price. How to switch pet insurance explains what a new insurer will treat as pre-existing, law or no law, and does pet insurance work out of state explains which of these guarantees travel with you if you move.
