## External-review route

**State-run process.** Ohio runs its own external review process meeting the federal standards, so an independent review there is handled through the state program rather than the federal one. This route is the one for insured plans, Marketplace, individual, and employer plans where an insurance company carries the risk. If your coverage is through a job and the employer pays the claims itself (a self-funded or self-insured plan, which is 63% of covered workers), the state process does not apply to you whatever your state operates, and your external review goes through the federal process instead. Your denial letter names your route; if it does not, ask your plan in writing whether the plan is self-funded.

Insurance got denied, what to do next?

We hear this most. [r/HealthInsurance, thread title](https://www.reddit.com/r/HealthInsurance/comments/1rdxwvi/insurance_got_denied_what_to_do_next/) , read September 3, 2026.

The number nobody else publishes. Not one of the 5,966 denials Antidote Health Plan of Ohio issued in Ohio reached the independent review its own staff do not decide, an explicit zero in this insurer's own filed row, not an absence. The stage was there the whole time and it binds the plan. Nationally 22.2% (1,092 of 4,918; interval 22.2-23.8% for counts CMS withheld; 32.6% without SelectHealth) of the reviews that got there were overturned.

Those 5,966 denials are 0.4% of every in-network denial recorded in Ohio in this release, which makes Antidote Health Plan of Ohio the 7th largest source of denials of the 7 insurers reporting there. Spread across its 28 plans in the state that is about 213 denials per plan. 429 internal appeals were filed against those 5,966 denials. Every one of those denials carried the same two dates the tool at the top of this page works out.

The clock your letter has to describe, in actual dates

Two dates matter more than anything else on this page, and they run the same in Ohio as everywhere else. You have 180 days from the date on your denial notice to file the internal appeal, and then 4 months from the final internal denial to ask for an independent external review. If waiting would seriously jeopardize your health you can ask for both to be expedited, decided in about 72 hours . Both timeframes are federal, not your insurer's choice, [29 CFR 2560.503-1](https://www.ecfr.gov/current/title-29/section-2560.503-1) ( [PDF](https://www.govinfo.gov/content/pkg/CFR-2024-title29-vol9/pdf/CFR-2024-title29-vol9-sec2560-503-1.pdf) ) and [45 CFR 147.136](https://www.ecfr.gov/current/title-45/section-147.136) ( [PDF](https://www.govinfo.gov/content/pkg/CFR-2024-title45-vol2/pdf/CFR-2024-title45-vol2-sec147-136.pdf) ), in plain English at [HealthCare.gov](https://www.healthcare.gov/appeal-insurance-company-decision/internal-appeals/) , and your own denial letter states the ones that govern your plan. The PDFs are the same sections on govinfo.gov, which serves them without a challenge page, so an automated reader can check these two dates as easily as you can.

Data verified November 4, 2026 · CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain

You are not alone, and here is the measured version of that sentence: 5,966 in-network claims were denied by Antidote Health Plan of Ohio in Ohio in a single plan year. A denial rate is a fact about an insurer's book of business. It is not a judgment about you, and it is not the last word on your claim.

- Of the 7 insurers reporting a denial rate in Ohio, Antidote Health Plan of Ohio is the fifth highest at 12.6%. The highest in the state is 24.5% and the lowest is 7.9%.

- That is 3.1 percentage points below the 15.7% national average across this dataset, and 0.1 points below the Ohio average of 12.7%.

- Behind the percentage: 47,326 in-network claims were processed under 28 plans in Ohio, and 5,966 of them came back denied.

- For every 10,000 claims Antidote Health Plan of Ohio denied, about 719 came back as an internal appeal. The other 9,281 stopped at the letter.

- Of the internal appeals it did receive, Antidote Health Plan of Ohio overturned 36.6% , 157 claims that started life as a no.

- Not one of those denials reached independent external review, the stage whose decision the plan is required by law to accept, and where nationally 22.2% (1,092 of 4,918; interval 22.2-23.8% for counts CMS withheld; 32.6% without SelectHealth) are overturned.

- Its most-recorded denial reason is other reasons at 100% of its categorized denials, against 32.4% nationally, a heavier share than the country as a whole. That is the denial mix, not an outcome rate.

- Antidote Health Plan of Ohio accounts for 0.4% of every in-network claim denied in Ohio in this file.

- By raw volume it is the 128th largest source of denials among the 135 insurer-state records in the file that report one.

- Where Antidote Health Plan of Ohio differs most from the national mix is [other reasons](/denial-reasons/other) : 100% of its categorized denials in Ohio against 32.4% across the file.

- Read the other way round: 41,360 of those 47,326 in-network claims were paid, 87.4% of everything Antidote Health Plan of Ohio processed in Ohio.

- Spread across the 28 plans it reports in Ohio, that is about 213 denied claims per plan, on about 1,690 claims processed per plan.

- Its reason columns add up to 538 categorized rows against 5,966 denials, 9% of them, and every reason share on this page is a share of that first figure rather than of the second.

- Against the file as a whole, this one record is 0% of the 83,907,852 in-network claim denials reported by every issuer in it.

What to do tonight

- Find the reason code on your denial letter. The reason Antidote Health Plan of Ohio records most often in Ohio is other reasons , but yours may be one of the other 8, copy the exact wording and code off your own letter tonight, because that sentence is what your appeal has to answer.

- Ask Antidote Health Plan of Ohio in Ohio for the clinical criteria they judged you against. Under [29 CFR 2560.503-1](https://www.ecfr.gov/current/title-29/section-2560.503-1) they have to hand you the claim file and the policy they applied, free, on request, and you cannot argue with a checklist you have never read.

- Put both deadlines on your calendar before you go to bed. 180 days from the date on the letter for the internal appeal, 4 months from the final internal denial for external review. The free calculator on this page turns your date into the two calendar dates in about ten seconds. Antidote Health Plan of Ohio overturned 36.6% of the internal appeals it did receive, 157 claims, so the stage you are about to start is not decorative.

None of those three steps costs anything. Anyone charging you to do them is selling you something you can do yourself in twenty minutes.

| Ohio average | 12.7% | -0.1 pts |
| National average (this dataset) | 15.7% | -3.1 pts |

Antidote Health Plan of Ohio sits at or below the national average across this dataset. A denial rate is a property of the insurer's book of business, coding practice, plan design, the population it covers, not evidence about the merits of any one claim, including yours.

## What happened to appeals

| Stage | Filed | Overturned |
| --- | --- | --- |
| Internal appeal (to Antidote Health Plan of Ohio) | 429 | 36.6% |
| External review (independent) | 0 | not reported |

Read that again: Antidote Health Plan of Ohio denied 5,966 claims in Ohio, and not one went to independent external review. External review is free to you and the insurer must follow the decision.

## The gap nobody escalated

5,966 claims denied. 429 internal appeals filed. None reached independent external review. Nationally 22.2% (1,092 of 4,918; interval 22.2-23.8% for counts CMS withheld; 32.6% without SelectHealth) of external reviews are overturned and the decision binds the plan.

That is arithmetic from the reported figures, not a prediction: nobody can say what those specific denials would have done at review, because they never got there. What the numbers do establish is that the binding stage was almost entirely unused here.

What that record means for your own Antidote Health Plan of Ohio letter, and by when. Antidote Health Plan of Ohio overturned 36.6% of the 429 internal appeals its Ohio members filed against 5,966 denials, and not one of those Ohio denials went on to the independent stage whose decision binds the plan, Antidote Health Plan of Ohio's own rows in the plan-year 2027 release of the CMS Transparency in Coverage file, read November 4, 2026 ( [data.healthcare.gov](https://data.healthcare.gov/) ). Whichever way that lands, nobody files the appeal for you, and the filing runs on a clock set by which plan you hold: an employer or Marketplace plan gives you at least 180 days from the denial notice to file the internal appeal ( [29 CFR 2560.503-1(h)(3)(i)](https://www.govinfo.gov/content/pkg/CFR-2024-title29-vol9/pdf/CFR-2024-title29-vol9-sec2560-503-1.pdf) , carried onto individual-market coverage by [45 CFR 147.136(b)(3)(i)](https://www.govinfo.gov/content/pkg/CFR-2024-title45-vol2/pdf/CFR-2024-title45-vol2-sec147-136.pdf) ), while Medicare Advantage gives you 65 calendar days from the date of its notice ( [CMS](https://www.cms.gov/medicare/appeals-grievances/managed-care/reconsideration-advantage-health-plan-part-c) , [42 CFR 422.582(b)](https://www.ecfr.gov/current/title-42/section-422.582) ) and Medicaid managed care 60 calendar days from the date on the notice ( [42 CFR 438.402(c)(2)(ii)](https://www.ecfr.gov/current/title-42/section-438.402) ), both stages free, and the three steps above are the whole of what to do tonight, so take the date printed on your Antidote Health Plan of Ohio notice and file well inside whichever of those windows is yours. The free steps are above; the [$29 kit](/appeal-kit) is the same clock with the letters pre-filled for Antidote Health Plan of Ohio in Ohio. One payment. No subscription. No cut of your claim.

## Antidote Health Plan of Ohio inside Ohio

Your denial did not happen in a national average. It happened in a state market, alongside 8 other insurers reporting into the same federal file, and these are that market's own figures.

- Across the whole of Ohio, the 9 insurers reporting in this file processed 11,919,238 in-network claims and denied 1,509,307 of them, a state denial rate of 12.7%. Antidote Health Plan of Ohio is one of those 9.

- That puts Ohio 23th of 29 states by denial rate, 3 points below the 15.7% national average, before you get to what Antidote Health Plan of Ohio did inside it.

- Ohio recorded 20,482 internal appeals against those denials: one appeal for every 74 claims the state's insurers refused. Antidote Health Plan of Ohio's own ratio is one for every 14.

- Independent external review was reached 114 times in the whole of Ohio, once for every 13,240 denials, against one in 17,061 nationally. None of them came from Antidote Health Plan of Ohio's denials.

- Of the Ohio external reviews that were filed, 31 were overturned, 27.2%. That percentage is measured on 114 reviews, which is why the count beside it matters more than the rate does when you are deciding whether to file against Antidote Health Plan of Ohio.

- The reason Ohio's insurers record most often is [administrative reason](/denial-reasons/administrative) , 423,239 claims, 20.1% of the state's categorized denials. Antidote Health Plan of Ohio records other reasons most often instead, which is the argument your letter will need to answer.

- The other insurers an Ohio reader could have bought from run from 24.5% ( [Summa Insurance Company, Inc.](/insurers/summa-insurance-company-inc--oh) ) to 7.9% ( [Community Insurance Company](/insurers/community-insurance-company--oh) ). Antidote Health Plan of Ohio at 12.6% sits between the two.

- Put the two together and Antidote Health Plan of Ohio is responsible for 0.4% of every in-network claim denied in Ohio in this release, from 0.4% of the claims the state's insurers processed.

- Every Ohio figure in this section is that state's own row in the same federal file Antidote Health Plan of Ohio's numbers above come from, [CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain](https://data.healthcare.gov/) , and the full Ohio page is free at [/states/ohio](/states/ohio) .

The last column is each reason's share of all categorized denials nationally, so you can see where Antidote Health Plan of Ohio's mix in Ohio differs from everyone else's. This is denial mix , not overturn rate by reason , the federal file does not report appeal outcomes broken down by denial reason, and we do not imply otherwise.

## Questions

##### Is Antidote Health Plan of Ohio's denial rate in Ohio high?

12.6% against a national average of 15.7% across the plans in this dataset. It is at or below average. A denial rate describes the insurer, not the merits of your claim.

##### How many people appealed an Antidote Health Plan of Ohio denial in Ohio, and how many won?

429 internal appeals were filed against 5,966 denials, and 36.6% of them were overturned (157 claims). Not one went on to independent external review, the stage whose decision is binding on the plan.

##### What does Antidote Health Plan of Ohio deny most often in Ohio?

Other reasons, 538 claims, 100% of this issuer's categorized denials, against 32.4% nationally. This is the denial-reason mix; the federal file does not report overturn rates by reason.

##### How long do I have to appeal an Antidote Health Plan of Ohio denial in Ohio?

Generally 180 days from the date on the denial notice to file the internal appeal, then generally four months from the final internal denial to request independent external review. Expedited review, decided in about 72 hours, is available where delay would seriously jeopardize your health. Those timeframes are federal, so they are identical for every insurer reporting in Ohio, Antidote Health Plan of Ohio included, what varies by state is who runs the independent review at the end. Your own denial letter states the deadlines that govern your plan; that letter is the authority.

##### Does appealing an Antidote Health Plan of Ohio denial in Ohio cost anything?

The internal appeal to Antidote Health Plan of Ohio is free. External review is free under the HHS-administered federal process; where an issuer uses a contracted independent review organization or a state process, any fee is capped at $25 per review. Nobody in Ohio can be charged more than that to file one.

##### Can Antidote Health Plan of Ohio ignore an external review decision in Ohio?

No, and that is the whole point of the stage. External review decisions are binding on the plan by law, which is what makes the zero external reviews recorded against 5,966 Antidote Health Plan of Ohio denials in Ohio the striking number on this page.

The line on this page we would read twice is the one that says not one of Antidote Health Plan of Ohio's 5,966 denials in Ohio reached independent review. We are not going to tell you that you will win. This page prints the insurer's own reported numbers whichever way they fall. If what it says does not match the letter in your hand, write to us and we will correct the page.

## The pages that answer the next question

- [Every insurer reporting in Ohio](/states/ohio) , the state's own row, the 9 companies filing there, and the Ohio insurance department's consumer number, read at source.

- [Aspirus Health Plan, Inc. in Wisconsin](/insurers/aspirus-health-plan-inc--wi) , 15.4% of in-network claims denied, 57,728 of them, the neighboring record in this file.

- [Avera Health Plans, Inc. in Iowa](/insurers/avera-health-plans-inc--ia) , the neighboring record in this file; CMS reported no usable denial count for it.

- [Avera Health Plans, Inc. in South Dakota](/insurers/avera-health-plans-inc--sd) , 3.5% of in-network claims denied, 17,773 of them, the neighboring record in this file.

- [If your employer pays the claims itself](/self-funded-denial) , then Antidote Health Plan of Ohio is only administering the plan, your state's external review has no power over the denial, and the route is federal. It is the first question our own calculator asks. 9 insurers report in Ohio; whether your plan is one of theirs at all is what that page settles.

- [If it was refused before the treatment](/prior-authorization-denied) , a prior-authorization refusal from Antidote Health Plan of Ohio runs on the same two federal clocks as a denied claim, and it can be appealed while the treatment is still ahead of you. 1,509,307 in-network claims were denied in Ohio in this release; a refusal before the treatment is not counted among them and is appealed the same way.

- [Before you pay a lawyer](/before-you-call-a-lawyer) , two free appeals run before anyone bills you by the hour, and Antidote Health Plan of Ohio has to hand you the claim file for nothing under 29 CFR 2560.503-1. Free help in Ohio starts with the state consumer line printed on that state's page.

Your dates are ready. [Write the letter, free](/appeal-letter)

## The two federal clocks

The clock your letter has to describe, in actual dates Whatever else is on the page, these two dates are the page. You have 180 days from the date on your denial notice to file the internal appeal, and then 4 months from the final internal denial to ask for an independent external review. If waiting would seriously jeopardize your health you can ask for both to be expedited, decided in about 72 hours . Both timeframes are federal, not your insurer's choice, 29 CFR 2560.503-1 ( PDF ) and 45 CFR 147.136 ( PDF ), in plain English at HealthCare.gov , and your own denial letter states the ones that govern your plan. The PDFs are the same sections on govinfo.gov, which serves them without a challenge page, so an automated reader can check these two dates as easily as you can.

## How rare the second appeal is

You are not alone, measured rather than said: 83,907,852 in-network claims were denied in a single plan year, and only 4,918 of them, one in 17,061, ever reached the independent review stage. Of the ones that did, 22.2% (1,092 of 4,918; interval 22.2-23.8% for counts CMS withheld; 32.6% without SelectHealth) were overturned.

## What is free here, and what the one paid thing costs

Denied a claim? Insurers upheld 165,863 of the 262,982 internal appeals counted in 2024, 63.1% ( KFF ).

## What we will not pretend

What we will not pretend. We cannot overturn your denial. Only your plan, or an independent reviewer, can do that. We cannot make your plan cover a service it genuinely excludes. We cannot guarantee external review applies to your denial. It covers medical judgment, experimental or investigational determinations, and rescission, a purely administrative denial may not qualify, and we say so on those pages rather than selling you past it. We have no customer testimonials and publish none. Our evidence is the federal dataset and the regulation cites, both of which you can check.

## Which release these figures are

Which release these figures are Every number on this page is the plan-year 2027 Transparency in Coverage file, issued October 22, 2026, covering plan-year 2025 claims. This is the newest plan year CMS has published: there is no Transparency in Coverage file for a plan year after 2027. The dataset list is at data.healthcare.gov . A test in this site’s build fetches that list on every run and fails if CMS publishes a plan year we have not acknowledged here. Every earlier release, plan-year 2024, plan-year 2025, plan-year 2026, is kept alongside it so the record is visible rather than a single year’s snapshot; /about says what changed between them. From the plan-year 2024 release to the plan-year 2026 release, external reviews filed went from 2,336 to 5,881. Overturned reviews went from 32.8% in the plan-year 2026 release to 22.2% in plan-year 2027, or from 32.6% to 32.6% without SelectHealth. We do not compare filed or overturned counts across plan-years 2026 and 2027. Some issuers may have counted pre-service appeals in their 2026 cells.

Rights and timeframes: 29 CFR 2560.503-1 (180 days, and your free right to the claim file) and 45 CFR 147.136 (4 months, and what qualifies), explained at HealthCare.gov . Expedited review is decided in about 72 hours under both sections. Reading either regulation from a script rather than a browser: eCFR answers automated fetches with a challenge page, so the same two sections are mirrored as government PDFs at govinfo.gov (29 CFR 2560.503-1) and govinfo.gov (45 CFR 147.136) .

## Who publishes this

Denial Facts publishes federal data about health insurance claim denials. We are independent: not affiliated with, endorsed by, or acting for any insurer, government agency, or review organization. We are not a law firm, a medical provider, or an insurance producer, and nothing here is legal, medical, or insurance advice. Data: CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain. Figures cover individual-market Qualified Health Plans on the federal Exchange and come from the plan-year 2027 release, issued October 22, 2026, covering plan-year 2025 claims. This is the newest plan year CMS has published: there is no Transparency in Coverage file for a plan year after 2027. See where the data comes from .
