Insurance got denied, what to do next?
Those 18,534 denials are 0.9% of every in-network denial recorded in Oklahoma in this release, which makes Oscar Insurance Company the 5th largest source of denials of the 5 insurers reporting there. Spread across its 14 plans in the state that is about 1,324 denials per plan. 762 internal appeals were filed against those 18,534 denials. Every one of those denials carried the same two dates the tool at the top of this page works out.
Two dates matter more than anything else on this page, and they run the same in Oklahoma 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 (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.
You are not alone, and here is the measured version of that sentence: 18,534 in-network claims were denied by Oscar Insurance Company in Oklahoma 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 5 insurers reporting a denial rate in Oklahoma, Oscar Insurance Company is the third highest at 16%. The highest in the state is 25.4% and the lowest is 13.5%.
- That is 0.3 percentage points above the 15.7% national average across this dataset, and 1 points below the Oklahoma average of 17%.
- Behind the percentage: 115,959 in-network claims were processed under 14 plans in Oklahoma, and 18,534 of them came back denied.
- For every 10,000 claims Oscar Insurance Company denied, about 411 came back as an internal appeal. The other 9,589 stopped at the letter.
- Of the internal appeals it did receive, Oscar Insurance Company overturned 27.17%, 207 claims that started life as a no.
- In Oklahoma, Oscar Insurance Company reported 16%, and the same company files in 8 other states in this file, where the rate is not the same in any of them: 18.7% in Tennessee, 18.4% in Missouri, 18.2% in Michigan, down to 15.3% in Texas. Which state the plan was bought in moves the odds more than the brand on the card does.
- Oscar Insurance Company accounts for 0.9% of every in-network claim denied in Oklahoma in this file.
- By raw volume it is the 118th largest source of denials among the 135 insurer-state records in the file that report one.
- Read the other way round: 97,425 of those 115,959 in-network claims were paid, 84% of everything Oscar Insurance Company processed in Oklahoma.
- Spread across the 14 plans it reports in Oklahoma, that is about 1,324 denied claims per plan, on about 8,283 claims processed per plan.
- 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.
- Find the reason code on your denial letter. The federal file records no denial-reason breakdown for Oscar Insurance Company in Oklahoma, so this page cannot tell you which of the 9 categories yours will be, your letter can, and it has to. Copy the exact wording and the code off it tonight: that sentence is what your appeal has to answer.
- Ask Oscar Insurance Company in Oklahoma for the clinical criteria they judged you against. Under 29 CFR 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. Oscar Insurance Company overturned 27.17% of the internal appeals it did receive, 207 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.
How that compares
| Denial rate | Rate | Difference |
|---|---|---|

| National average (this dataset) | 15.7% | +0.3 pts |
Oscar Insurance Company denies 0.3 percentage points more of its in-network claims than 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 Oscar Insurance Company) | 762 | 27.17% |

What that record means for your own Oscar Insurance Company letter, and by when. Oscar Insurance Company overturned 27.17% of the 762 internal appeals its Oklahoma members filed against 18,534 denials, and the Oklahoma escalation count for Oscar Insurance Company is the figure this page names as absent at the top, so how many of those denials went on to the independent stage is not something this page can tell you, Oscar Insurance Company's own rows in the plan-year 2027 release of the CMS Transparency in Coverage file, read November 4, 2026 (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), carried onto individual-market coverage by 45 CFR 147.136(b)(3)(i)), while Medicare Advantage gives you 65 calendar days from the date of its notice (CMS, 42 CFR 422.582(b)) and Medicaid managed care 60 calendar days from the date on the notice (42 CFR 438.402(c)(2)(ii)), both stages free, and the three steps above are the whole of what to do tonight, so take the date printed on your Oscar Insurance Company notice and file well inside whichever of those windows is yours. The free steps are above; the $29 kit is the same clock with the letters pre-filled for Oscar Insurance Company in Oklahoma. One payment. No subscription. No cut of your claim.
Oscar Insurance Company inside Oklahoma

- Independent external review was reached 34 times in the whole of Oklahoma, once for every 62,242 denials, against one in 17,061 nationally. How many came from Oscar Insurance Company's denials is not on the record, that is the Oklahoma figure this page names as absent at the top and sources at the foot.
- Of the Oklahoma external reviews that were filed, 0 were overturned, 0%. That percentage is measured on 34 reviews, which is why the count beside it matters more than the rate does when you are deciding whether to file against Oscar Insurance Company.
- The reason Oklahoma's insurers record most often is other reasons, 1,017,174 claims, 30.5% of the state's categorized denials.
- The other insurers an Oklahoma reader could have bought from run from 25.4% (UnitedHealthcare of Oklahoma, Inc.) to 13.5% (Celtic Insurance Company). Oscar Insurance Company at 16% sits between the two.
- Put the two together and Oscar Insurance Company is responsible for 0.9% of every in-network claim denied in Oklahoma in this release, from 0.9% of the claims the state's insurers processed.
- Every Oklahoma figure in this section is that state's own row in the same federal file Oscar Insurance Company's numbers above come from, CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain, and the full Oklahoma page is free at /states/oklahoma.

The Oscar Insurance Company figures on this page, the 16% denial rate, the 18,534 denials, are this issuer’s own reported rows in that file.

Counts: CMS Transparency in Coverage Public Use File (PY2027 release, PY2025 claims), data.healthcare.gov — US Government public domain. 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.

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).
