| Gate | Evidence needed | If the answer is no or unclear |
|---|---|---|
| This pet can enroll in this product | A current offer for the actual age, species and state. | A national product description is not yet a usable plan. |
| The necessary benefit can be selected | The offered schedule and any required endorsement. | A general existing-condition feature may not reach that expense. |
| This condition can become eligible | The exact exception, history requirements and prospective start rule. | Keep the condition outside assumed reimbursement. |
Run these in order. A favorable answer at the third gate in an advertisement cannot repair a failed second gate in your personal offer. Nor does successful enrollment prove that every condition is within the selected benefits.
For example, imagine an adult dog with a known condition that the insurer says requires an optional benefit. If that benefit cannot be added for this dog, the general promise of future pre-existing-condition eligibility is not enough. Ask for an explicit explanation of the dependency rather than assuming one headline overrides another rule.
The three-gate test is a comparison method, not a personal coverage determination. It is useful precisely because it can remove an unusable advertised exception before you spend time comparing its price.
