Pet Insurance Glossary: 43 Terms Defined Plainly

Updated May 202643 termsAnchored to NAIC Model Act

Pet insurance has its own vocabulary — and most claim disputes come down to a single misunderstood word. This reference defines the 43 terms that actually decide whether a vet bill gets reimbursed, anchored to the NAIC Pet Insurance Model Act (2022) and to standard U.S. carrier policy structures. Every term links to a deeper explainer where the nuance matters.

Basics & Policy Structure

The foundational vocabulary of any pet insurance contract.

Pet Insurance → Deep dive: A property-and-casualty policy that reimburses you for eligible veterinary expenses, regulated state by state under the NAIC Pet Insurance Model Act (2022). Read full explanation →
Premium → Deep dive: The amount you pay each month or year to keep your policy active. Driven by species, breed, age, ZIP code, and the deductible / reimbursement / annual-limit combination you choose. Read full explanation →
Policy → Deep dive: The legal contract between you and the insurer that defines what is covered, what is excluded, and how claims are paid. Read full explanation →
Declarations Page → Deep dive: The summary cover sheet of your policy showing your pet, premium, deductible, reimbursement %, annual limit, and effective dates. Read full explanation →
Effective Date → Deep dive: The exact date your coverage begins. Waiting periods are measured from this date — not from the date you applied. Read full explanation →
Policy Year → Deep dive: The 12-month period your annual deductible and annual limit reset on. Almost always tied to your effective date, not the calendar year. Read full explanation →

Cost Mechanics

How premiums, deductibles, and limits actually work together.

Deductible → Deep dive: The amount you pay out of pocket per policy year before reimbursement begins. Kanguro offers $100–$1,000 annual deductibles. Read full explanation →
Per-Incident Deductible → Deep dive: A deductible that resets every new condition, instead of once per year. Common at older carriers; Kanguro uses an annual deductible (simpler math, lower lifetime cost for chronic conditions). Read full explanation →
Reimbursement Percentage → Deep dive: The share of the eligible bill your insurer pays back after the deductible. Kanguro offers 70%, 80%, or 90%. Read full explanation →
Co-Insurance → Deep dive: The portion of an eligible bill you keep paying after the deductible — the inverse of your reimbursement %. At 80% reimbursement, your co-insurance is 20%. Read full explanation →
Co-Pay → Deep dive: A fixed dollar amount paid per visit. Common in human health insurance; rare in pet insurance, which uses co-insurance instead. Read full explanation →
Annual Limit → Deep dive: The maximum dollars your insurer will reimburse in a single policy year. Kanguro offers $5,000–$30,000 annual limits. Read full explanation →
Lifetime Limit → Deep dive: A cap on total reimbursements for the life of the policy. Most modern carriers (including Kanguro) do not impose lifetime limits — only annual. Read full explanation →
Per-Incident Limit → Deep dive: A cap on how much can be reimbursed for a single condition. Kanguro does not cap by incident — only by annual maximum. Read full explanation →
Benefit Schedule → Deep dive: A fixed-payout table that limits reimbursement per procedure (e.g., "MRI: $500 max"). Used by older policies; Kanguro reimburses against the actual bill, not a fixed schedule. Read full explanation →

Coverage Scope

What is — and isn’t — eligible for reimbursement.

Accident-Only Coverage → Deep dive: A reduced-cost plan covering injuries (broken bones, swallowed objects, lacerations) but not illnesses. Cheaper, but excludes cancer, allergies, and chronic disease. Read full explanation →
Accident & Illness Coverage → Deep dive: The standard pet insurance plan. Covers both injuries and illnesses (cancer, infections, hereditary conditions, chronic disease) — excludes pre-existing conditions and routine wellness. Read full explanation →
Wellness Plan → Deep dive: A separate add-on (technically not insurance, per NAIC) that reimburses routine preventive care: annual exams, vaccines, dental cleaning, spay/neuter, flea/tick prevention. Read full explanation →
Hereditary Condition → Deep dive: A genetic condition passed from parent to pet (e.g., hip dysplasia in retrievers, syringomyelia in cavaliers). Kanguro covers hereditary conditions if they are not pre-existing at enrollment. Read full explanation →
Congenital Condition → Deep dive: A condition present at birth, whether or not it has shown symptoms (e.g., heart murmur, liver shunt). Treatment is typically covered if undiagnosed before enrollment. Read full explanation →
Chronic Condition → Deep dive: A long-term condition requiring ongoing treatment (allergies, diabetes, arthritis, IBD). Covered annually as long as it was not pre-existing — making annual deductibles preferable to per-incident. Read full explanation →
Bilateral Condition → Deep dive: A condition that can occur on both sides of the body — cruciate ligament tears, hip dysplasia, glaucoma. If one side was pre-existing, the other side is typically also excluded under a bilateral exclusion. Read full explanation →
Breed-Specific Condition → Deep dive: A condition statistically more common in a given breed (BOAS in bulldogs, IVDD in dachshunds, polycystic kidney disease in Persians). Coverage is not breed-restricted, but pre-existing exclusions still apply. Read full explanation →
Prescription Medication → Deep dive: Vet-prescribed drugs for a covered condition. Reimbursed at the same percentage as the underlying treatment. Over-the-counter supplements and food are typically excluded. Read full explanation →
Alternative & Complementary Therapy → Deep dive: Acupuncture, chiropractic care, hydrotherapy, laser therapy. Covered when prescribed by a licensed vet for a covered condition; rules vary by carrier. Read full explanation →
Behavioral Coverage → Deep dive: Reimbursement for vet-prescribed behavioral treatment — separation anxiety, aggression, compulsive disorders. Often included in standard A&I plans. Read full explanation →
Dental Coverage → Deep dive: Coverage for dental disease, broken teeth, and oral surgery. Routine cleanings are usually wellness add-on territory; pathology (extractions, periodontal disease) falls under A&I. Read full explanation →

Exclusions & Conditions

The fine-print rules that decide whether a claim gets paid.

Pre-Existing Condition → Deep dive: Per the NAIC Model Act: any condition for which a pet showed signs, was diagnosed, or was treated before the policy effective date or during the waiting period. Pre-existing conditions are excluded across the entire industry. Read full explanation →
Curable Pre-Existing → Deep dive: A pre-existing condition that is fully resolved (often defined as 180+ symptom-free days). Some carriers will then cover future occurrences as new conditions; others maintain the exclusion permanently. Always check carrier-specific rules. Read full explanation →
Bilateral Exclusion → Deep dive: A clause that excludes a condition on the opposite side of the body if the original side was pre-existing. Common for cruciate tears, hip dysplasia, ear infections, cataracts, and glaucoma. Read full explanation →
Verifiable Source → Deep dive: NAIC term for the documented evidence (vet records, SOAP notes, lab results) an insurer uses to determine whether a condition was pre-existing. Without verifiable records, claim denials can be appealed. Read full explanation →

Policy Lifecycle

How coverage starts, renews, and can be changed mid-term.

Accident Waiting Period → Deep dive: The delay between your effective date and when accident coverage begins. Kanguro: 14 days. Accidents during this window are treated as pre-existing. Read full explanation →
Illness Waiting Period → Deep dive: The delay before illness coverage begins. Kanguro: 14 days. Common across the industry, with some carriers extending to 30 days. Read full explanation →
Orthopedic Waiting Period → Deep dive: The longer waiting period for cruciate, hip, and other orthopedic conditions. Kanguro: 6 months — reducible to 14 days with vet-confirmed records of a healthy musculoskeletal exam. Read full explanation →
Renewal → Deep dive: The annual continuation of your policy. NAIC requires guaranteed-renewable pet policies — the insurer cannot drop you for filing claims or for your pet aging. Read full explanation →
Free-Look Period → Deep dive: A regulator-mandated window (typically 14–30 days) after you buy the policy during which you can cancel for a full premium refund, provided no claims have been filed. Read full explanation →
Rider / Endorsement → Deep dive: An optional add-on that modifies your base policy — wellness add-ons, exam-fee coverage, alternative-therapy upgrades. Each rider has its own premium and rules. Read full explanation →

Claims & Reimbursement

The mechanics of getting paid back after a vet visit.

Claim → Deep dive: A request for reimbursement on an eligible vet bill. Most carriers (Kanguro included) process claims in ~5 business days; some routine cases approve instantly via AI-assisted review. Read full explanation →
Reimbursement Process → Deep dive: You pay the vet at the time of service, submit the invoice + medical records to your insurer, and receive payment by direct deposit or check after the deductible is met. Read full explanation →
Explanation of Benefits (EOB) → Deep dive: The itemized statement showing how your insurer calculated reimbursement: total billed, eligible amount, deductible applied, reimbursement %, paid amount, and any denied line items. Read full explanation →
SOAP Notes → Deep dive: Vet exam records following the format Subjective / Objective / Assessment / Plan. Insurers request these to verify a condition was not pre-existing. Read full explanation →
Direct Vet Pay → Deep dive: A payment option where the insurer pays the veterinary clinic directly, bypassing reimbursement. Some carriers (Kanguro included) offer this with participating clinics. Read full explanation →
Vet Network → Deep dive: The set of veterinarians eligible for coverage. Most pet insurers — Kanguro included — have NO network restrictions: any licensed vet in the U.S. is accepted. Read full explanation →
