Insurance got denied, what to do next?
We hear this most. r/HealthInsurance, thread title, read September 3, 2026.
The number nobody else publishes. Not one of the 198,069 denials Hawaii Medical Service Association issued in Hawaii 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 32.8% of the reviews that got there were overturned.

Those 198,069 denials are 99.7% of every in-network denial recorded in Hawaii in this release, which makes Hawaii Medical Service Association the 1st largest source of denials of the 2 insurers reporting there. Spread across its 7 plans in the state that is about 28,296 denials per plan. 104 internal appeals were filed against those 198,069 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 Hawaii 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: 198,069 in-network claims were denied by Hawaii Medical Service Association in Hawaii 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 Hawaii Medical Service Association records most often in Hawaii 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.
  2. Ask Hawaii Medical Service Association in Hawaii 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. Hawaii Medical Service Association overturned 50% of the internal appeals it did receive, 52 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.

Hawaii Medical Service Association denies 8.7 percentage points more of its in-network claims than the national average across this dataset.

Read that again: Hawaii Medical Service Association denied 198,069 claims in Hawaii, 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

198,069 claims denied. 104 internal appeals filed. None 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 Hawaii Medical Service Association letter, and by when. Hawaii Medical Service Association overturned 50% of the 104 internal appeals its Hawaii members filed against 198,069 denials, and not one of those Hawaii denials went on to the independent stage whose decision binds the plan, Hawaii Medical Service Association'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 Hawaii Medical Service Association 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 Hawaii Medical Service Association in Hawaii. One payment. No subscription. No cut of your claim.

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 Hawaii, Hawaii Medical Service Association 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 a Hawaii Medical Service Association denial in Hawaii cost anything?

The internal appeal to Hawaii Medical Service Association 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 Hawaii can be charged more than that to file one.

Can Hawaii Medical Service Association ignore an external review decision in Hawaii?

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 198,069 Hawaii Medical Service Association denials in Hawaii the striking number on this page.

The line on this page I would read twice is the one that says not one of Hawaii Medical Service Association's 198,069 denials in Hawaii reached independent review. I am 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 me and I will correct the page.

Where these numbers come from

The Hawaii Medical Service Association figures on this page, the 27.4% denial rate, the 198,069 denials and the 0 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 Hawaii Medical Service Association notice, you know that Hawaii runs the external review itself, and you have the letter, free, on this screen, tonight.
