Deductible vs out-of-pocket maximum calculator

See how deductible and out-of-pocket max interact before you pay a bill.

Your deductible is what you pay for covered care before the plan starts paying its share. Your out-of-pocket maximum caps total cost sharing for covered in-network care in a plan year. After you hit the OOP max, the plan pays 100% of covered services until the year resets. Use this calculator to see how one claim affects both buckets.

The deductible is paid first on many plans. Copays and coinsurance after the deductible still count toward your out-of-pocket maximum. Premiums and out-of-network charges may not count—check your Summary of Benefits.

Complete guide

How to use Deductible vs OOP in your appeal workflow

How it works

  1. You enter denial facts from your EOB or denial letter — member ID, claim number, service, and the reason the payer gave.
  2. AppealFlow drafts structured appeal language you can edit in the browser. Optional checkboxes add ERISA full-and-fair-review language, No Surprises Act references, or expedited-review requests when they fit your facts.
  3. Export PDF or Word, keep a copy for your records, and file through the portal, fax, or mailing address on your notice before the deadline printed there.

Deductible vs out-of-pocket maximum

The deductible is the amount you pay for covered services before the plan begins paying its share (except for services the plan covers with a copay before deductible). The out-of-pocket maximum caps total in-network cost sharing for essential health benefits in a plan year on ACA plans. After you reach the OOP max, covered in-network care should be paid at 100% until the plan year resets.

Using the calculator before you pay a bill

Enter your remaining deductible and OOP max from your member portal, then add the allowed amount from your EOB. See how much of the claim applies to deductible versus coinsurance. If the provider bill exceeds the EOB allowed amount for in-network care, dispute the balance before paying.

Appeals when the plan misapplied cost sharing

If the plan applied deductible to preventive care that should be covered at 100%, or ignored an accumulated OOP max, appeal with portal screenshots and prior EOBs showing year-to-date totals.

Worked example: estimating a 180-day internal window

Your commercial plan sends an adverse benefit determination dated March 15, 2026 denying physical therapy as not medically necessary. The notice says you may request an internal appeal within 180 days. Adding 180 calendar days to March 15 lands on September 11, 2026 (verify with your plan — some policies use business days or a fixed date on the form). If you need continued care while waiting, ask whether the plan offers an expedited review and document any worsening symptoms. If the internal appeal is upheld, the same notice often explains whether you may request external review and which state or federal program applies. Save portal uploads, fax confirmations, and certified mail receipts.

Appeal deadlines by plan type (reference)

Deadlines are plan-specific. The table summarizes common federal frameworks cited on many notices. Your adverse benefit determination letter controls filing dates and channels.

Plan typeInternal appealExternal reviewUrgent / expedited
ACA marketplace / fully insured individual & small groupOften 60–180 days from the adverse determination (check notice). ACA internal claims and appeals rules require written notice of rights.After exhausting internal appeals, many enrollees may request external review; federal rules set minimum external review rights for qualifying plans (see 45 CFR 147.136).Urgent medical situations may qualify for expedited review; many plans must respond within 72 hours when delay could seriously jeopardize health (45 CFR 147.136(b)(3) framework).
Self-funded employer plan (ERISA)29 CFR 2560.503-1 requires a reasonable opportunity for a full and fair review; many plans allow about 180 days to request review of an adverse benefit determination unless the plan document grants longer.External review rights depend on plan design and state law for insured portions; many ERISA plans use independent review vendors after internal exhaustion.Expedited review must be available when the timeframe for a standard review could seriously jeopardize life or health (29 CFR 2560.503-1(h)(3)(i)).
Original Medicare (Part A & B)Medicare uses redetermination (Level 1) by the Medicare Administrative Contractor — typically 120 days from the date of the initial determination on the MSN.Reconsideration (Level 2), ALJ hearing, and further levels follow CMS Medicare appeals guidance — not the same clocks as commercial insurance.Expedited Medicare determinations exist for certain hospital and SNF situations; follow instructions on the MSN.
Medicare Advantage (Part C)Organization determination and plan-level appeals follow CMS Medicare Advantage rules; use the plan's forms and clocks on the denial.After plan-level appeals, enrollees may request CMS review or, for some issues, state external review when applicable.Part C plans must offer expedited reviews for urgent requests per CMS marketing/appeals requirements.
Medicare Part D (prescription drugs)Coverage determinations and exceptions use PBM/plan Part D forms; standard determination timeframes are set in CMS Part D regulations.Appeal to the Independent Review Entity (IRE) after plan-level denial of a standard or expedited determination.Expedited exceptions and appeals exist when waiting could seriously harm health; request expedited processing in writing.
Medicaid / CHIP (state)Each state Medicaid agency sets fair hearing and appeal timelines; use the notice from your managed care plan or state agency.State fair hearing after managed care appeal exhaustion; timelines vary by state and benefit type.Many states allow expedited hearings when delay would jeopardize health; cite urgency on the request form.

Cite 29 CFR 2560.503-1 for many ERISA group health plans and 45 CFR 147.136 for many non-grandfathered individual/small group plans. Medicare and Medicaid use separate statutes and forms.

Common mistakes

  • Treating an illustrative calculator result as a legal deadline without reading your notice.
  • Filing with the medical claims address when the denial is a pharmacy benefit determination.
  • Skipping the internal appeal and going straight to external review before the notice allows it.

What to do next

  • Save proof of filing (portal screenshot, fax confirmation, or certified mail receipt).
  • If the plan requests more records, respond within the timeframe on the follow-up letter.
  • When internal appeals are exhausted, read your notice for external review or state complaint rights.
