This page does not rank insurers, does not recommend one, and earns nothing from any of them. It explains the clauses that decide whether a claim gets paid, quoted from the policy documents themselves. Every insurer named is named because its wording is public and says something clearly. Your own policy is the one that counts, and the wording differs.
This surprises people at the counter. The NAIC, the body US insurance regulators belong to, puts it plainly in its guide for regulators.
Most plans include a reimbursement model, meaning the insured must pay out of pocket to the veterinarian and be reimbursed by the insurer.
There are exceptions. Trupanion's software can pay the hospital at checkout, so you pay only your share. Pets Best will pay a vet directly per claim if the vet signs its release form. Everyone else, you are out of pocket first and the money comes back later. If a four-thousand-dollar bill would be a problem on the day even with a policy, that is the thing to plan for.
Nearly every US policy is built from three settings you choose when you buy.
An annual deductible is paid once in the policy year, whatever goes wrong. A per-incident deductible is paid again for every new condition. Three separate problems in one year means paying it three times. The NAIC has costed the difference from the insurer's side:
Coverage with an annual deductible routinely costs 4% to 6% more than a per incident deductible plan.
So a per-incident policy quoting a few percent cheaper is not a discount, it is a different product.
There is a third thing nobody mentions: the order. Take the deductible off first and then apply the percentage, or apply the percentage first and then take off the deductible, and you get different money. Embrace publishes the worked example itself. On a $1,200 bill with a $200 deductible at 80 percent, deductible first pays $800 and percentage first pays $760. Embrace applies the deductible first. Pets Best's own definition applies the coinsurance first. Ask which one your policy does.
This is the single most misunderstood clause in the whole product, and it is not close. The definition in the NAIC's model act, which insurers reproduce almost word for word, is this:
any condition for which a veterinarian provided medical advice, the pet received treatment for, or the pet displayed signs or symptoms consistent with the stated condition prior to the effective date of a pet insurance policy or during any waiting period.
Read displayed signs or symptoms again. No diagnosis is required, and three separate policies say so outright. AKC's terms: symptoms count "whether or not diagnosed by a veterinarian". Healthy Paws: "there doesn't need to be a diagnosis". Embrace: anything "noticed by you or your veterinarian" before the policy started.
In practice that means a line in a chart is enough. An unexplained limp your vet wrote down two years ago, an itch that was mentioned and never chased, a note that says tartar. None of them were a diagnosis. All of them can be cited later.
How far back they can look also varies, and here the wording that looks stricter is often the kinder one. Trupanion states 18 months. Fetch states 365 days. AKC and Healthy Paws state no period at all, only "prior to the effective date", which means anything in the record, ever.
Some insurers will let a resolved condition become eligible again if the animal stays clear for long enough. The window is not standardized.
Accident and illness waiting periods are short and everyone quotes them. The orthopedic ones are long and almost nobody does. The NAIC flags this itself: insurers "may add longer waiting periods for specific coverages such as orthopedics or cruciate ligament events".
This is what the policy documents say about knees, hips and spines.
| Insurer | Accident | Illness | Knee, hip and spine |
|---|---|---|---|
| AKC / PetPartners | 3 days | 14 days | 12 months for cruciate ligament, and 12 months for IVDD |
| Healthy Paws | 15 days | 15 days | 12 months for hip dysplasia. In 16 named states it is 30 days and waived by a clinical exam. Cruciate stated elsewhere as 15 days |
| Pets Best | 3 days | 14 days | 6 months for cruciate events, reducible through pre-approved channels with a vet certificate before purchase |
| Lemonade | 2 days | 14 days | 6 months for cruciate events. No exam waiver in the policy read |
| Fetch | 15 days | 15 days | 6 months for knee and hip, waivable by a vet exam noting no pre-existing knee problems |
| Embrace | none | 14 days | Varies by state. Reducible with a vet-completed orthopedic report card |
| Spot | 14 days | 14 days | 14 days, same as everything else |
| Trupanion | 5 days | 30 days | No separate period. It says so: "we do not have different waiting periods for specific conditions" |
Read from each insurer's own policy wording or published terms, September 2026. Fetch's policy form gives the exam window as 30 days and its FAQ gives 180 days, and both are Fetch documents, so check the declarations page you were actually sent rather than either number here. Waiting periods also vary by state.
Two things follow. If you buy a policy the week your dog starts limping, the limp is pre-existing and the surgery may be a year away from cover. And if you are buying for a breed with a known joint problem, the orthopedic clause is the clause that matters, not the headline price.
Policies use the term bilateral condition, and it does more work than its plain meaning suggests. AKC defines it as "a condition or disease that affects both sides of the body (example: cruciate ligament, eyes, ears, limbs, and lameness)", then excludes treatment for such a condition on one side "if that condition was a pre-existing condition on the other side of the body".
Fetch says it without any softening:
If your pet has received treatment or has shown clinical signs of a cruciate or soft tissue injury to one knee prior to the effective date of this policy or during the first 6 months of this policy, where no certificate of knee health has been provided, then the other knee is automatically excluded from coverage.
Note that the window reaches into the first six months of the policy, not just before it. Healthy Paws goes further and removes causation from the question, excluding future treatment of a leg where cruciate problems existed in another leg "regardless of whether or not the new signs or symptoms are related". Spot says knee and ligament conditions are bilateral "regardless of cause".
It is not only knees. Pets Best's list of bilateral conditions names luxating patellas, cruciate events, glaucoma, entropion, ectropion, hip dysplasia, elbow dysplasia, cataracts, cherry eye and osteochondritis dissecans, and applies the exclusion if the pet had a matching pre-existing condition "at any time" on "either side of the body". An ear infection in one ear, before you enrolled, can reach the other ear.
These were excluded in every accident-and-illness policy read for this page. Some are sold back as add-ons, which is a different thing from being covered.
The dental exclusion has a sting worth knowing about. Pets Best requires that from three years of age, the teeth "must have been cleaned and examined under general anesthesia by a Veterinarian in the thirteen months before the date of service" for a periodontal disease claim. The cleaning the policy will not pay for is a precondition of the dental disease claim it might.
On a recheck that finds nothing, the consultation fee is the bill. Whether it is covered varies more than anything else on this page.
So on a ninety-dollar recheck for a condition that is fully covered, several of these policies pay nothing, because the only line on the invoice is the one they exclude.
Insurers ask for a vet exam, and it is easy to read that as protective. Fetch's terms point the other way:
Any medical condition(s), clinical sign(s), behavioral disorder(s) or illness(es) observed or recorded during the first exam, and all costs associated therewith, are automatically excluded from coverage.
The same visit that satisfies the orthopedic requirement can put a new exclusion on the policy. That is not a reason to skip it. It is a reason to know that the record made that day is the record they will use.
The rating factors are not a secret. The Casualty Actuarial Society lists species, breed, age, territory and your chosen deductible and percentage as the primary ones, with gender, spay or neuter status and working status as secondary. The NAIC puts numbers on several of them.
One belief worth correcting: Healthy Paws states that its "premium increases are not based on your individual claim submissions". Rates move with the breed, age and area, not with whether you claimed.
There is no published per-breed price table from any filed rate or insurer document. Any figure that tells you a French Bulldog costs exactly so much more than a Labrador came from scraping quotes, not from the insurer. The category spread above is the honest version.
Whether to buy it. That turns on one question no page can answer for you: if the bill came to five thousand dollars next month, could you pay it without it changing anything. If yes, insurance is a choice about smoothing costs. If no, it is a choice about whether the option to treat exists at all.
What we can do is show you the real numbers on both sides. The bills are on the vet costs page, taken from millions of claims and published price lists rather than from estimates.
What treatment actually costs is on how much a vet visit costs, and what a pet actually costs builds the whole budget. The conditions people insure against are on the breed pages: each one lists what that breed is recorded as being treated for, and the health tests to ask a breeder for. If your animal is already on something, what the vet just prescribed has the label.
