| History | Coverage question | Evidence to request |
|---|---|---|
| First side had relevant signs before the applicable start or waiting-period end. | Does the clause exclude the matching condition on the other side? | Exact bilateral and pre-existing wording plus the medical facts relied upon. |
| First side developed an eligible condition after the relevant coverage rules were met. | Can later counterpart treatment also qualify? | Written explanation of both-side eligibility under the current form. |
| Later problem is on the opposite side but may have a different cause. | Is it the same condition under this contract? | Clinical explanation and insurer’s reason for linking or separating the events. |
A later surgery date alone cannot answer the first question. Give the insurer the accurate records from before and after enrollment, including symptoms noted before a formal diagnosis. Do not describe an earlier limp as irrelevant merely because the other leg is now the one being treated.
