Hawaii Medical Service Association denied 198,069 of 723,658 in-network claims in Hawaii; every one of those denials had these same two dates on it. Across Hawaii as a whole the insurers in this file denied 27% of in-network claims, 198,653 of them, and 137 were appealed.
Hawaii Medical Service Association denied 27.4% of in-network claims in Hawaii, 198,069 claims out of 723,658.
Insurance got denied, what to do next?
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.
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.
- Of the 2 insurers reporting a denial rate in Hawaii, Hawaii Medical Service Association is the first highest at 27.4%. The highest in the state is 27.4% and the lowest is 5.1%.
- That is 8.7 percentage points above the 18.7% national average across this dataset, and 0.4 points above the Hawaii average of 27%.
- Behind the percentage: 723,658 in-network claims were processed under 7 plans in Hawaii, and 198,069 of them came back denied.
- For every 10,000 claims Hawaii Medical Service Association denied, about 5 came back as an internal appeal. The other 9,995 stopped at the letter.
- Of the internal appeals it did receive, Hawaii Medical Service Association overturned 50%, 52 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 32.8% are overturned.
- Its most-recorded denial reason is other reasons at 64.4% of its categorized denials, against 32.3% nationally, a heavier share than the country as a whole. That is the denial mix, not an outcome rate.
- Hawaii Medical Service Association accounts for 99.7% of every in-network claim denied in Hawaii in this file.
- By raw volume it is the 74th largest source of denials among the 158 insurer-state records in the file that report one.
- After that, its second-most-recorded reason is administrative reason, 32,706 claims, 15.5% of its categorized denials.
- Third on its own list is benefit limit reached, 19,968 claims, 9.5% of what Hawaii Medical Service Association categorized in Hawaii. Between them the top three account for 89.4% of its categorized denials.
- Where Hawaii Medical Service Association differs most from the national mix is other reasons: 64.4% of its categorized denials in Hawaii against 32.3% across the file.
- Read the other way round: 525,589 of those 723,658 in-network claims were paid, 72.6% of everything Hawaii Medical Service Association processed in Hawaii.
- Spread across the 7 plans it reports in Hawaii, that is about 28,296 denied claims per plan, on about 103,380 claims processed per plan.
- Its reason columns add up to 210,795 categorized rows against 198,069 denials, 106.4% of them, and every reason share on this page is a share of that first figure rather than of the second.
- Its smallest recorded category in Hawaii is provider out of network, 14 claims, 0% of what Hawaii Medical Service Association categorized there.
- Against the file as a whole, this one record is 0.2% of the 84,502,749 in-network claim denials reported by every issuer in it.
- 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.
- 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.
- 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.
How that compares
| Denial rate | Rate | Difference |
|---|---|---|
| Hawaii Medical Service Association | 27.4% | , |
| Hawaii average | 27% | +0.4 pts |
| National average (this dataset) | 18.7% | +8.7 pts |
Hawaii Medical Service Association denies 8.7 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 Hawaii Medical Service Association) | 104 | 50% |
| External review (independent) | 0 | 0% |
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.
Hawaii Medical Service Association inside Hawaii
Your denial did not happen in a national average. It happened in a state market, alongside 1 other insurer reporting into the same federal file, and these are that market's own figures.
- Across the whole of Hawaii, the 2 insurers reporting in this file processed 735,147 in-network claims and denied 198,653 of them, a state denial rate of 27%. Hawaii Medical Service Association is one of those 2.
- That puts Hawaii first of 30 states by denial rate, 8.3 points above the 18.7% national average, before you get to what Hawaii Medical Service Association did inside it.
- Hawaii recorded 137 internal appeals against those denials: one appeal for every 1,450 claims the state's insurers refused. Hawaii Medical Service Association's own ratio is one for every 1,905.
- Not one denial in Hawaii reached independent external review in the reported year, not Hawaii Medical Service Association's and not any other insurer's in the state. That is the stage whose decision the plan is required by law to accept.
- The reason Hawaii's insurers record most often is other reasons, 135,996 claims, 64.3% of the state's categorized denials. Hawaii Medical Service Association records the same one most often, so your letter is likely to say it too.
- The other insurers a Hawaii reader could have bought from run from 5.1% (Kaiser Foundation Health Plan, Inc.) to 5.1% (Kaiser Foundation Health Plan, Inc.). Hawaii Medical Service Association at 27.4% sits above all of them.
- Put the two together and Hawaii Medical Service Association is responsible for 99.7% of every in-network claim denied in Hawaii in this release, from 98.4% of the claims the state's insurers processed.
- Every Hawaii figure in this section is that state's own row in the same federal file Hawaii Medical Service Association's numbers above come from, CMS Transparency in Coverage Public Use File (PY2026 release, PY2024 claims), data.healthcare.gov — US Government public domain, and the full Hawaii page is free at /states/hawaii.

The last column is each reason's share of all categorized denials nationally, so you can see where Hawaii Medical Service Association's mix in Hawaii 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.

How long do I have to appeal a Hawaii Medical Service Association denial in Hawaii?
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.
