| Illustrative line | Amount | Treatment in this example |
|---|---|---|
| Total clinic invoice | $1,260 | Amount paid to the clinic |
| Excluded charges | $160 | Not reimbursable under the assumed contract |
| Eligible charges | $1,100 | Starting point for the benefit calculation |
| Unmet deductible | $250 | Assumed amount still outstanding |
| Reimbursement percentage | 80% | Fictional setting used only to demonstrate the math |
If this hypothetical policy deducts $250 first, the calculation is ($1,100 − $250) × 80% = $680 . Your final share of the clinic bill is $580, excluding premiums.
If another hypothetical contract applies 80% first and then subtracts the deductible, the payment is ($1,100 × 80%) − $250 = $630 . Your share becomes $630. Both examples use the same headline settings; the order changes the result by $50.
These are alternative arithmetic models, not quotations of a named insurer’s formula. Ask the insurer to show the calculation using its own wording. Do not select whichever sequence produces the larger payment.
