Good to know: Independent ToolsKo worksheet. Official references reviewed November 11, 2026. Example inputs are not current offers or personal advice. For a single covered in-network service with a confirmed allowed amount, individual remaining deductible and remaining applicable out-of-pocket limit in the same plan year. Assumes the deductible applies first, then your coinsurance, with all modeled patient spending counting toward that limit. Not for copays, preventive exceptions, separate/family accumulators, out-of-network/noncovered charges, balance billing, multiple claims, prescription tiers, Original Medicare or plans without this structure. Does not determine coverage, medical necessity, legal liability or the final bill. Use insurer accumulator figures before this claim; premiums and amounts not counted toward the limit are excluded. Actual claim order and processing may change the result. No medical details, names or member numbers are needed.
How to use it (step by step)
- 1Confirm with your insurer that this service follows deductible-then-coinsurance rules and get the covered in-network allowed amount, not the provider’s sticker price.
- 2Enter remaining deductible, your coinsurance percentage and remaining applicable out-of-pocket limit before this claim. Use the same individual and plan year.
- 3Read the modeled patient/plan split and check your insurer’s estimate or Explanation of Benefits. This does not establish a final amount owed.
