Key Takeaways
- Standard accident and illness policies cover surgery, cancer, hereditary conditions, and prescription medications, but only if the condition isn’t pre-existing.
- Spaying, neutering, vaccinations, and dental cleanings require a wellness add-on; they are excluded from every standard policy.
- Pre-existing conditions, cosmetic procedures, and breeding costs are never covered, regardless of plan type or carrier. The pre-existing condition definition, specifically how carriers treat curable versus chronic conditions, is where most claim disputes start. Read that section of the policy before you buy.

Pet insurance covers unexpected veterinary expenses. That sentence does a lot of work, and the gap between what it implies and what a policy actually pays is where most claim disputes live.
The baseline product, an accident and illness policy, is designed for things that go wrong after you buy coverage. A broken leg from a fall off the couch. A cancer diagnosis at age seven. An intestinal blockage from swallowed socks. What it is not designed for is anything predictable, elective, or present before day one of coverage. Understanding that split explains roughly 90 percent of the coverage questions people search for.
This article goes through the major categories one at a time, with the actual answer and the conditions attached to it.
The Coverage Framework: Accident vs. Illness vs. Wellness
Most pet insurance policies in the U.S. are sold in one of two configurations. Accident-only policies cover injuries, lacerations, fractures, poisoning, bite wounds, foreign body ingestion, trauma from being hit by a car. Accident and illness policies add everything from infections and allergies to cancer, diabetes, and hereditary conditions. The vast majority of pet owners buying coverage today choose accident and illness.
What neither of those configurations covers is preventive care. Annual wellness exams, vaccinations, flea and tick prevention, dental cleanings, spay and neuter. These require a separate wellness add-on or a standalone wellness plan. Wellness coverage is sold as a reimbursement schedule, not insurance in the actuarial sense. You pay a higher premium; the plan reimburses a fixed list of preventive services up to a defined annual cap, usually $200–$450.
That three-way split, accident, illness, wellness, is the organizing principle behind almost every specific coverage question. Per NAPHIA’s 2026 State of the Industry Report, only 4.27% of U.S. pets currently carry insurance, which means most owners are encountering these distinctions for the first time at the claim stage, not the shopping stage.
Does Pet Insurance Cover Surgery?
Yes, when the surgery is medically necessary to treat a covered accident or illness. This is one of the clearest yes answers in pet insurance, because surgery is just a treatment method, not a separate coverage category. The question the insurer asks is not “is this surgery?” but “is the underlying condition covered?”
Soft tissue surgery, orthopedic surgery, and emergency surgery all fall within standard accident and illness coverage when they connect to a covered event. A dog that swallows a corn cob needs emergency abdominal surgery; that’s covered as a foreign body ingestion. A cat diagnosed with a urethral blockage needs surgery; that’s covered as an illness. A dog that tears its ACL playing fetch needs orthopedic repair; that’s covered as an accident.
If you are searching for pet insurance that covers surgery, what you actually need is any standard accident and illness policy. Surgery coverage is not a premium feature you have to seek out. It is included by default.
Does Pet Insurance Cover Hip Dysplasia?
Most major insurers cover hip dysplasia, but the caveats are important enough that the answer can flip on a single detail.
Hip dysplasia is a hereditary orthopedic condition where the ball and socket of the hip joint don’t develop correctly. It’s common in large breeds. German Shepherds, Labrador Retrievers, Golden Retrievers, Rottweilers. Because it’s hereditary, it’s the kind of condition insurers have historically been most cautious about, and the coverage terms reflect that caution.
The standard requirement is that the condition must not be pre-existing. That means no prior symptoms, no prior diagnosis, and no veterinary records showing gait abnormalities or hip scoring before the policy started. Most carriers also impose an orthopedic waiting period, commonly six months, before orthopedic conditions are covered. Enroll your Labrador at eight weeks and you can file an orthopedic claim starting around month seven. Enroll your three-year-old dog who already has a documented limp and you will not.
Carriers including Embrace, Healthy Paws, and Trupanion all cover hip dysplasia under standard accident and illness terms, subject to the pre-existing and waiting period conditions. A small number of carriers have historically excluded hip dysplasia in breeds with high statistical incidence, but that practice is uncommon in the current market.
If hip dysplasia is a meaningful concern for your breed, read the orthopedic waiting period terms before you buy, and buy early.
Does Pet Insurance Cover Spaying and Neutering?
No. Spay and neuter procedures are elective and preventive, which puts them outside the scope of a standard accident and illness policy by definition.
This surprises a lot of first-time buyers, often because they’re buying a policy while their puppy or kitten is young and spay/neuter is the next big vet expense on their horizon. The policy they’re buying simply does not cover that expense.
A wellness add-on will typically reimburse $50–$200 toward a spay or neuter, depending on the carrier and the tier. That reimbursement is often the most financially significant single-item benefit on a wellness schedule, especially for cats where the surgery is less expensive. Whether that benefit justifies the added premium is a math problem covered in the wellness section below.
If you are looking for pet insurance that covers spaying, that means you need a policy with a wellness add-on, not a standard accident and illness plan.
Does Pet Insurance Cover Vaccinations?
Standard accident and illness policies do not cover vaccinations. Vaccines are preventive care, administered to a healthy animal. The entire premise of standard pet insurance coverage is reimbursing unexpected, non-preventive veterinary costs.
A wellness add-on does cover vaccinations, typically reimbursing $50–$150 per year toward core vaccines. Whether the math works in your favor depends on how many vaccines your pet needs annually and what you’re paying in additional premium for the wellness rider. If you are already doing annual wellness visits and your vet charges $120 in vaccines per year, a wellness add-on that costs $20/month in additional premium is netting out at roughly zero before you account for any other wellness benefits.
Does Pet Insurance Cover Dental?
The answer splits cleanly between dental illness and dental wellness, and most people conflate them.
Dental illness. Fractured teeth, tooth root abscesses, periodontal disease requiring extraction or surgical treatment is covered under most standard accident and illness policies. The Veterinary Oral Health Council has documented periodontal disease as the most common clinical condition in dogs and cats over three years old. When it advances to the point where extraction is medically necessary, that claim is typically paid.
Dental cleaning is not covered under a standard policy. Cleanings are preventive and elective. A wellness add-on will typically include a cleaning reimbursement of $75–$150 per year.
The practical consequence: if your dog’s gum disease progresses to the point where the vet needs to pull four teeth under general anesthesia, that’s a covered claim. The routine cleaning that might have prevented it is not. That gap is real, and it is worth factoring in when you’re evaluating whether to add a wellness rider.
Some carriers draw the dental illness line differently. Read the dental section of any policy’s exclusions carefully. A few carriers exclude dental disease entirely or apply a separate sublimit.
Does Pet Insurance Cover Routine Care?
Only with a wellness add-on. “Routine care” is effectively a synonym for preventive care, and preventive care is explicitly excluded from every standard accident and illness policy in the U.S. market.
A wellness add-on or standalone wellness plan covers a defined reimbursement schedule that typically includes the annual wellness exam, core vaccines, flea and tick prevention products, heartworm testing and prevention, dental cleaning, and spay/neuter. Some plans include microchipping, deworming, and fecal exams. The schedule is fixed by the carrier. You submit a claim; they reimburse up to the listed amount for each service.
This is not insurance in the traditional sense. There’s no deductible, no coinsurance, no actuarial risk transfer. You are essentially prepaying for services at a slight discount in exchange for administrative convenience. Whether that trade makes sense depends on whether you actually use the covered services, which is addressed in the wellness section below.
Hereditary and Congenital Conditions
Most major insurers now cover hereditary and congenital conditions under standard accident and illness policies, provided the condition is not pre-existing. This is an important distinction from how the market worked a decade ago, when hereditary exclusions were far more common.
Conditions in this category include hip dysplasia, elbow dysplasia, intervertebral disc disease, brachycephalic obstructive airway syndrome in flat-faced breeds, heart defects, and breed-specific eye conditions. Coverage is subject to the same pre-existing condition exclusion that applies everywhere else. A condition that appeared or was diagnosed before the policy start date, or during a waiting period, is excluded.
The practical implication: the younger and healthier your pet is when you enroll, the broader your effective coverage will be. Every prior vet record that documents a symptom is a potential basis for a pre-existing condition exclusion on a future claim.
Cancer Treatment
Cancer is covered under standard accident and illness policies, including chemotherapy, radiation therapy, surgery, oncology specialist visits, and diagnostic imaging related to the diagnosis. Most carriers do not apply a separate sublimit for cancer, meaning it draws from the same annual or lifetime limit as all other covered conditions.
This matters financially because cancer treatment for dogs and cats has become substantially more sophisticated and expensive. According to the American Veterinary Medical Association, nearly half of dogs over age 10 develop some form of cancer. A full course of chemotherapy for canine lymphoma runs $3,000–$10,000 depending on the protocol, the dog’s size, and the surgical center. Radiation therapy adds another $4,000–$10,000 when it’s part of the treatment plan. Diagnostic workup before the first dose, biopsies, CT scans, specialist consultations, can push total treatment costs well above those figures at major veterinary oncology centers.
A year of premiums at $60/month is $720. One standard chemo protocol is five to fifteen times that. The math on cancer coverage is the single clearest case for carrying an accident and illness policy into your dog’s senior years, when the risk is highest and the temptation to let coverage lapse because of rising premiums is strongest.
Prescription Medications
Prescription medications are covered when prescribed for a covered condition. If your dog develops hypothyroidism after the policy start date, the thyroid medication is a covered ongoing expense. If your cat is diagnosed with inflammatory bowel disease, the prescription diet and immunosuppressive medication are covered.
General supplements without a prescription, over-the-counter medications, and food are not covered unless specifically prescribed for a documented medical condition and identified as medically necessary in the veterinary record. “My vet suggested glucosamine” is not the same as a prescription. The documentation distinction matters at claim time.
Alternative Therapies
Coverage for acupuncture, chiropractic care, hydrotherapy, and physical rehabilitation varies by carrier and is not universal. Trupanion covers it under their standard policy when prescribed by a licensed veterinarian for a covered condition. Other carriers require an endorsement or exclude it entirely.
If you have a large breed dog with orthopedic issues and you anticipate using rehabilitation therapy post-surgery, this is worth checking before you buy. It is not a benefit to assume.
What Pet Insurance Never Covers
The exclusion list is shorter than the coverage list, but the items on it are definitive.
Pre-existing conditions are excluded by every carrier without exception. This is the foundational underwriting rule for the entire product category. A condition that existed, showed symptoms, or was diagnosed before coverage began cannot become a covered condition by changing policies or waiting, with one limited exception for curable conditions at carriers that explicitly define them that way (see below).
Cosmetic procedures are excluded across the board. Ear cropping, tail docking, declawing, and dewclaw removal performed for aesthetic or convenience reasons are not covered. These are elective procedures with no medical necessity.
Breeding, pregnancy, and whelping costs are excluded. Complications during pregnancy may be covered in some policies, but the breeding program itself is not insurable under a standard pet policy.
Grooming is not covered. Dental cleanings are not covered under standard plans. Food, treats, and supplements are not covered unless they constitute a prescription diet with documented medical necessity.
Behavioral training without an underlying medical condition is generally not covered. Some carriers will cover behavioral treatment when the behavioral issue is traced to a covered medical diagnosis, anxiety secondary to a neurological condition, for example, but standalone training programs are not.
The Wellness Add-On: When It Pays and When It Doesn’t
A wellness add-on costs roughly $15–$30 per month in additional premium at most major carriers, depending on tier. The reimbursement schedule typically totals $200–$450 in covered services per year. Per NAPHIA, the average annual premium for a dog accident and illness policy was $749 in 2024, and wellness riders sit on top of that. At the lower-cost wellness tier, you are paying $180/year for $200 in potential reimbursements. The margin is thin, and it only exists if you file every eligible claim.
The value proposition is real in specific situations. If you have a puppy or kitten in their first two years, the concentration of preventive care visits, vaccines, flea and tick prevention, spay or neuter, and a microchip, creates a year where the schedule pays out close to its maximum. If you have a small breed dog that requires dental cleanings every 12 months, the cleaning reimbursement alone may justify the premium on a mid-tier wellness plan.
Where it stops making sense is when you are paying $30/month for a $350 annual benefit and consistently using only $100 of it because you forget to submit the flea prevention claims. Wellness plans do not roll over. Unused reimbursements expire at the end of the policy year. Carriers know this and price accordingly.
Before adding a wellness rider, list the specific preventive services you actually use in a calendar year and match them to the reimbursement schedule line by line. If the reimbursable total exceeds the annual premium cost, buy it. If it doesn’t, the money is better applied to a lower deductible on your accident and illness policy.

The Pre-Existing Condition Exclusion in Practice
The language insurers use in their exclusion clauses matters more than most buyers realize. A “pre-existing condition” is typically defined as any condition for which clinical signs existed before the policy effective date, not just conditions that were formally diagnosed.
That distinction has real consequences. If your dog visited the vet at age one with occasional limping and the vet noted “possible orthopedic issue, monitoring” in the record, that notation can be used to exclude a hip dysplasia claim filed three years later. The insurer’s vet team reviews all prior medical records at claim time. They are not reading for confirmation. They are reading for basis to exclude.
This is not a cynical practice. It is actuarially necessary. If pre-existing conditions could be covered, people would buy policies only after their pet was already sick, and the risk pool would collapse. But it is also not a consumer-friendly process when it surfaces during a $12,000 orthopedic claim. The time to understand how your insurer defines pre-existing is before the claim, not during it.
Pre-existing condition definitions vary in ways that matter for actual claim payouts. Embrace treats a resolved condition, a treated UTI, for instance, as no longer pre-existing after 12 symptom-free months, meaning it can become a covered condition in a future policy year. ASPCA Pet Insurance (administered by Crum & Forster, a Fairfax subsidiary) applies a 180-day symptom-free window for curable conditions, with a specific carve-out: any prior knee or ligament condition is excluded permanently regardless of resolution. Healthy Paws’ approach applies a lifetime exclusion to hereditary and congenital conditions when signs or symptoms appeared before the policy effective date, a treated UTI might qualify for reinstatement under some carriers, but a prior cruciate injury almost never does under the strictest definitions. Bilateral handling varies too: a right-knee ACL tear at Trupanion has historically made the left knee pre-existing; Embrace explicitly does not treat bilateral conditions that way. These differences are in the policy form, not the marketing site. Check them before you buy.
Most pet insurance brands are not the actual insurance carrier. They’re distribution-layer products sitting on top of roughly 12 actual underwriters. The brand on the marketing site is the distribution channel; the underwriter is who actually pays the claim and decides denials. ASPCA Pet Insurance is administered by Crum & Forster Pet Insurance Group (Fairfax). Pumpkin and Spot are underwritten by United States Fire Insurance, also a Fairfax subsidiary. Pets Best is underwritten by Independence American Insurance Company. Healthy Paws is Aon-owned and Chubb-underwritten. Trupanion is vertically integrated. Knowing the underwriter matters when you’re reading a pre-existing condition definition, because the underwriter, not the brand, sets the policy form and makes the call on borderline claims.
