Consider an invented sick-visit invoice for a cat: $140 for the examination, $260 for diagnostic testing and $100 for medication. The $500 total is not a veterinary price estimate. Assume the condition and the testing and medication are eligible, the remaining annual deductible is $200, the reimbursement rate is 80%, the policy subtracts the deductible first and no payout limit is reached.
| Illustrative plan design | Eligible amount assumed | Illustrative payment | Owner’s share of the full bill |
|---|---|---|---|
| Illness treatment included; exam fee excluded | $360 | ($360 − $200) × 80% = $128 | $372 |
| Same settings, with the exam charge eligible | $500 | ($500 − $200) × 80% = $240 | $260 |
The difference is $112 of reimbursement on this one fictional invoice. Compare that difference with the extra price of exam-fee coverage if the actual insurer offers it, without assuming this visit will occur or that either design is a real product. If the underlying condition is excluded, both illustrations stop being applicable; the percentage does not override the exclusion.
