| Expense path | What to establish |
|---|---|
| Treatment of the original injury | When did the injury happen relative to the effective date and any relevant wait? Buying now generally does not transfer an already-existing loss. |
| Later follow-up, rehabilitation or recurrence | Does the policy treat it as related to the original injury? A later invoice date does not make the underlying condition new. |
| An unrelated future accident or illness | Does the new event meet coverage definitions and timing, without falling under another exclusion? The old injury does not itself answer every future claim. |
Enrollment eligibility and claim eligibility are different. A company may allow you to buy a policy for the animal while excluding the existing injury. Ask about both, and obtain the offered policy rather than interpreting a completed quote as medical clearance.
