What Pet Insurance Actually Covers (and What It Never Will)

Most pet insurance complaints trace back to one moment: the claim that gets denied because the owner thought they were covered for something the policy never included. So before comparing prices, understand what these products actually are.

What standard plans cover

The core product in the US is the accident and illness plan. It reimburses a percentage of your vet bill (usually 70 to 90 percent, after a deductible) for:

• Accidents: broken bones, swallowed objects, cuts, bite wounds, toxin ingestion, being hit by a car.
• Illnesses: infections, cancer, diabetes, arthritis, allergies, skin conditions, digestive issues.
• Diagnostics: bloodwork, x-rays, ultrasounds, MRIs ordered for a covered condition.
• Treatment: surgery, hospitalization, prescription medications, and in most plans emergency and specialist care.
• Hereditary and congenital conditions: hip dysplasia, heart defects, eye disorders, as long as they were not symptomatic before enrollment. This matters enormously for purebreds.

What is never covered, anywhere

• Pre-existing conditions. The universal exclusion. Anything symptomatic before coverage started, even without a formal diagnosis. Some insurers (Spot among them) re-qualify curable conditions after 180 symptom-free days, but chronic conditions are excluded for the pet’s life.
• Waiting period claims. Illnesses that appear in the first 14 days, typically. Some orthopedic conditions carry 6-month waits unless waived after a vet exam.
• Breeding, pregnancy, whelping.
• Cosmetic and elective procedures: ear cropping, tail docking, declawing.

The gray zones that decide claims

These are the categories where plans genuinely differ, and where reading the sample policy before buying pays off:

Exam fees. The $80 to $350 fee for the visit itself. Some plans include it, some sell it as an add-on, some never cover it. Over a pet’s life this is hundreds of dollars of difference.

Dental illness. Almost everyone covers a tooth broken in an accident. Coverage for dental disease (infections, resorption, extractions) varies widely and often comes with requirements like annual cleanings to keep it valid.

Rehabilitation and alternative therapy. Physical therapy, hydrotherapy, acupuncture after surgery. Sometimes included, sometimes an add-on.

Prescription food and supplements. Usually capped or excluded, even when prescribed.

Behavioral treatment. Increasingly covered by newer plans, still excluded by many.

Wellness add-ons: read before buying

Most insurers sell a preventive care add-on covering vaccines, annual exams, flea and heartworm prevention, and sometimes routine dentals. These are not insurance; they are prepayment plans with a cap. If the add-on costs $25 a month and reimburses up to $450 a year of routine care you were buying anyway, it is a mild discount with extra paperwork. Run the arithmetic for your actual routine spending before adding it.

How to read any policy in 10 minutes

1. Download the sample policy (every insurer publishes one), not the marketing page.
2. Search for “exclusions” and read that section completely.
3. Check the waiting periods table, especially orthopedic.
4. Confirm whether exam fees are included.
5. Find the dental illness language.
6. Check how chronic conditions renew: a good plan covers a condition diagnosed this year in every future year, as long as you stay enrolled.
