Denied claims almost never come from a brand behaving badly. They come from a clause the owner never read, in a document the insurer published openly, before a bill made it matter. This page is the checklist we use on every policy we review, in the order that catches the most money. Read it with a sample policy open, and write down the answers rather than trusting your memory of the sales page.
What is the first clause to check in a pet insurance policy?
Start with the pre-existing definition and how far back the insurer looks, because it decides more denials than every other clause put together. A pre-existing condition is any illness or injury that showed symptoms before coverage started or during a waiting period, whether or not a vet ever named it.
The lookback is the part owners misjudge. There is no medical exam at enrollment, so nothing is checked when you buy. Insurers request your pet's veterinary records at the first claim, often from every clinic the pet has visited, and read them against the claim in front of them. A limp charted in March can exclude a cruciate claim in September. Full detail, including the four paths that remain for a pet with a diagnosis, is in our guide to pre-existing conditions.
Ask the policy two questions: how far back the records review reaches, and whether an enrollment gap restarts the clock.
What is a bilateral exclusion, and why does it cost so much?
A bilateral clause extends an exclusion from one side of the body to the other for paired conditions, so a problem in one knee, hip, or eye can exclude the matching part. Cruciate ligaments are the classic case, and Lemonade's policy follows the industry pattern: a cruciate tear before enrollment excludes the other knee.
The money involved is why this clause outranks most brand differences. CareCredit puts a TPLO cruciate repair at about $3,525 per knee. Sustainable Vet Group puts TPLO at most hospitals at $3,500 to $6,000 and up, with a lateral suture repair at $1,500 to $3,000 for the surgery alone. The same source states surgeons in California and New York charge 30 to 40 percent above those figures, and billed costs vary widely by region and clinic. One clause can therefore decide a four-figure outcome on a paired joint.
Ask which conditions the policy treats as bilateral. Hip dysplasia, cataracts, and cruciate disease are the usual candidates.
How long is the orthopedic waiting period?
Orthopedic conditions carry their own waiting period, which can run far longer than the ordinary illness wait. Across the US market accident waits run about 1 to 15 days and illness waits about 14 to 30 days, while orthopedic waits reach six months at some insurers.
Two verified examples show the range and the escape hatch. Embrace applies a 6-month orthopedic wait that an orthopedic waiver exam can reduce. Lemonade applies a 6-month wait to cruciate ligament events. Our reviews leave the orthopedic wait marked pending verification at most other insurers, because we publish day-counts only after confirming them against current policy documents rather than guessing them. The general rules are in pet insurance waiting periods.
Ask for the number in writing, and ask whether a waiver exam exists and what it costs.
Does the policy pay the exam fee?
Exam fees are included at some insurers and sold as a paid add-on at others, and the difference shows up on every single visit rather than once a year. CareCredit puts an emergency exam fee at $135 for dogs and $143 for cats, while Money, citing several sources, puts the emergency exam or base fee at $100 to $300.
Three verified positions in our reviews show the spread. Fetch includes sick-visit exam fees in the base policy. Embrace covers exam fees for accident and illness visits. Figo sells exam fees as an add-on, and so does Lemonade. A quote that looks cheaper because the exam fee sits outside it is not cheaper; it is unconfigured.
Ask whether exam fees are covered for illness visits, for emergency visits, and for recheck visits, since those can be answered differently.
Are there sublimits inside the annual limit?
A sublimit is a smaller cap that applies to one category inside your overall annual limit, and it can stop payment while thousands of dollars of headline limit remain unused. Dental illness is where we see it most often.
Our Embrace review is the one place our coverage maps currently record a named sublimit: an annual cap applies to dental illness. We mark the figure itself for verification against current documents rather than publishing a number we have not confirmed. Wellness riders work the same way by design, with a printed cap for each item, and the arithmetic for those is in wellness add-on costs.
Ask whether any category carries its own cap, and get the current figure rather than last year's.
Does the policy pay a share of the bill or a fixed scheduled amount?
Most US policies reimburse a percentage of the actual covered bill, but some products pay from a benefit schedule instead, meaning a fixed dollar amount per condition regardless of what your clinic charged. The two structures can look identical on a comparison table and behave very differently at the counter.
The test is simple. Percentage-of-bill policies track your invoice, so a higher-priced region raises the payout with the price. A benefit schedule does not move, so an expensive market erodes your coverage quietly. Veterinary services inflation has run at a 6.5 percent seven-year average annual rate per BLS data reported by PetfoodIndustry, which makes a fixed schedule worth less every year unless it is revised.
Ask the insurer to show you the payout calculation on a sample invoice from your own zip code.
Can the insurer refuse to cover an older pet, or refuse to renew?
Yes to both, and these two clauses decide whether coverage lasts as long as your pet does. Some insurers set an upper age limit for new enrollments, while others do not: Pumpkin enrolls with no breed restrictions and no upper age limit, which is the clearest counter-example in our reviews. The insurer-by-insurer picture is in pet insurance age limits.
Renewal is the sharper risk, because a pet policy is a one-year contract on both sides. Nationwide non-renewed roughly 100,000 policies in spring 2024, citing veterinary cost inflation, and ManyPets exited the US market entirely in late 2024. Coverage that must be renewed at 12 is worth less than the same coverage renewed at 3, and any guide that skips this is selling. What can and cannot change at your anniversary is in pet insurance renewals.
Ask what the insurer can change at renewal, and whether coverage for a condition already claimed continues.
Can an excluded condition ever come back into coverage?
Sometimes, through a curable-condition window that restores coverage after a symptom-free period, and the terms are insurer-specific rather than industry-wide. Three stated examples sit in our reviews. ASPCA Pet Health Insurance restores curable conditions after 180 symptom-free days, and Embrace states a 12-month symptom-free window. AKC Pet Insurance states that some pre-existing conditions may gain coverage after 365 days of continuous enrollment, with terms that apply.
Two conditions attach to all of them. The window applies to curable problems such as a resolved infection, never to chronic disease like diabetes or hip dysplasia. And a recurrence during the window resets the clock, so the symptom-free period has to be clean. Verify the wording in the policy documents before a window decides your purchase, because these clauses vary in ways the marketing summary does not capture.
What does this checklist not protect you from?
It does not protect you from the clauses you cannot read until you buy, and that is the limitation this page owes you. Policy documents are not equally easy to obtain before purchase, which is exactly why many rows in our own coverage maps read pending rather than covered. We mark a row verified only when the policy documents say so.
Two more gaps stay open. A clause can be clear and still be applied in a way you disagree with, which is what the claim denials guide exists for. And our own quoted premiums have not published yet, so a configuration you like cannot be priced here today: pending first quote run. Set the three policy levers with how to choose your deductible, limit, and reimbursement, then take this checklist to the sample policy before you enter a payment method.
