Insurance got denied, what to do next?
We hear this most. r/HealthInsurance, thread title, read September 3, 2026.
The number nobody else publishes. 517 denials by Oscar Insurance Company in Texas reached the independent review its own staff do not decide, and 176 of those were overturned, 34.04%. That is this insurer's own filed row in the federal file, not our estimate. We publish no success rate of our own, because we have none.

Those 764,285 denials are 3.4% of every in-network denial recorded in Texas in this release, which makes Oscar Insurance Company the 8th largest source of denials of the 14 insurers reporting there. Spread across its 100 plans in the state that is about 7,643 denials per plan. 38,325 internal appeals were filed against those 764,285 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 Texas 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.

Notice for Oscar Insurance Company in Texas, there is a deadline in this one. CMS says the HHS-Administered Federal External Review Process reopened on July 31, 2026. If your plan uses that process and you could not file between July 1, 2026 and August 3, 2026, CMS says you may be eligible for an extension and have until October 2, 2026 to request external review. If you filed before July 1, 2026 you do not need to resubmit; if you already have a final decision through the federal process, the extension does not apply to you. HealthCare.gov names one group this state-by-state page cannot show you: it says the extension may reach you if you have a state or local government plan in any state, not only in the states whose insurers use the federal process. Both pages were read at source on September 5, 2026 and this is what they said that day, the CCIIO external appeals page and HealthCare.gov on external review. Read them again before you rely on this: it is a live deadline and it has moved once already. Texas is one of the states CMS lists as using the federal process, so this applies to an insured plan bought there. If your plan uses a contracted independent review organization instead, none of this affects you.

You are not alone, and here is the measured version of that sentence: 764,285 in-network claims were denied by Oscar Insurance Company in Texas 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.

What to do tonight
  1. Find the reason code on your denial letter. The reason Oscar Insurance Company records most often in Texas is administrative reason, 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.
  2. Ask Oscar Insurance Company in Texas 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.
  3. 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 23.64% of the internal appeals it did receive, 9,061 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.

Oscar Insurance Company denies 6.8 percentage points more of its in-network claims than the national average across this dataset.

The gap nobody escalated

764,285 claims denied. 38,325 internal appeals filed. 517 reached independent external review. Nationally 32.8% 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 Oscar Insurance Company letter, and by when. Oscar Insurance Company overturned 23.64% of the 38,325 internal appeals its Texas members filed against 764,285 denials, and 517 of those Texas denials went on to the independent stage whose decision binds the plan, Oscar Insurance Company's own rows in the plan-year 2026 release of the CMS Transparency in Coverage file, read September 5, 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 60 calendar days after you receive its notice (42 CFR 422.582(b)) and Medicaid managed care the same 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 Texas. One payment. No subscription. No cut of your claim.

Nobody in Texas can be charged more than that to file one.

Can Oscar Insurance Company ignore an external review decision in Texas?

Where these numbers come from

The Oscar Insurance Company figures on this page, the 25.5% denial rate, the 764,285 denials and the 517 external reviews, are this issuer’s own reported rows in that file.

Counts: CMS Transparency in Coverage Public Use File (PY2026 release, PY2024 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. 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).

This page presents federal statistics and a general description of appeal rights created by federal law. It is not legal, medical, or insurance advice, and no outcome is guaranteed. Your denial letter and plan documents govern your specific case. Free help is available from your state's Consumer Assistance Program and from the federal Marketplace at HealthCare.gov.
Problem solved: You have both dates for your Oscar Insurance Company notice, you know that an insured plan in Texas goes to the federal process, and you have the letter, free, on this screen, tonight.
