Can the pet enroll?
This is an eligibility question. The insurer can offer a policy even when it excludes some of the pet’s history.
Will the present condition be paid for?
That requires the actual definition and any condition-specific benefit or exception. A policy purchase alone does not answer it.
A third question is often the most practical: what future unrelated care could the policy help fund? Do not reject all insurance automatically because one problem is excluded, but do not pay a premium assuming that the excluded problem will eventually become covered. Evaluate the remaining scope against the price.
For a pet already receiving treatment, maintain a separate budget for that known care while comparing future protection. The decision becomes clearer when a hoped-for exception is not being used as the only way to pay the current bill.
