United keeps denying my claims. I'm up to my ears in medical debt and I make close to nothing.
Those 740,183 denials are 51.1% of every in-network denial recorded in Arizona in this release, which makes UnitedHealthcare of Arizona, Inc. the 1st largest source of denials of the 6 insurers reporting there. Spread across its 15 plans in the state that is about 49,346 denials per plan. 1,462 internal appeals were filed against those 740,183 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 Arizona 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: 740,183 in-network claims were denied by UnitedHealthcare of Arizona, Inc. in Arizona 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 6 insurers reporting a denial rate in Arizona, UnitedHealthcare of Arizona, Inc. is the second highest at 24.5%. The highest in the state is 50.1% and the lowest is 9.5%.
- That is 8.8 percentage points above the 15.7% national average across this dataset, and 8.4 points above the Arizona average of 16.1%.
- Behind the percentage: 3,020,935 in-network claims were processed under 15 plans in Arizona, and 740,183 of them came back denied.
- For every 10,000 claims UnitedHealthcare of Arizona, Inc. denied, about 20 came back as an internal appeal. The other 9,980 stopped at the letter.
- Of the internal appeals it did receive, UnitedHealthcare of Arizona, Inc. overturned 54.04%, 790 claims that started life as a no.
- Its most-recorded denial reason is other reasons at 49.3% 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.
- UnitedHealthcare of Arizona, Inc. accounts for 51.1% of every in-network claim denied in Arizona in this file.
- By raw volume it is the 25th largest source of denials among the 135 insurer-state records in the file that report one.

- Where UnitedHealthcare of Arizona, Inc. differs most from the national mix is provider out of network: 28.8% of its categorized denials in Arizona against 9% across the file.
- Read the other way round: 2,280,752 of those 3,020,935 in-network claims were paid, 75.5% of everything UnitedHealthcare of Arizona, Inc. processed in Arizona.
- Spread across the 15 plans it reports in Arizona, that is about 49,346 denied claims per plan, on about 201,396 claims processed per plan.
- Its reason columns add up to 1,054,165 categorized rows against 740,183 denials, 142.4% 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 Arizona is experimental or investigational, 12 claims, 0% of what UnitedHealthcare of Arizona, Inc. categorized there.
- Against the file as a whole, this one record is 0.9% of the 83,907,852 in-network claim denials reported by every issuer in it.
- Find the reason code on your denial letter. The reason UnitedHealthcare of Arizona, Inc. records most often in Arizona 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 UnitedHealthcare of Arizona, Inc. in Arizona 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. UnitedHealthcare of Arizona, Inc. overturned 54.04% of the internal appeals it did receive, 790 claims, so the stage you are about to start is not decorative.

| National average (this dataset) | 15.7% | +8.8 pts |
UnitedHealthcare of Arizona, Inc. denies 8.8 percentage points more of its in-network claims than the national average across this dataset.

What happened to appeals

|---|---|---|
| Internal appeal (to UnitedHealthcare of Arizona, Inc.) | 1,462 | 54.04% |

What that record means for your own UnitedHealthcare of Arizona, Inc. letter, and by when. UnitedHealthcare of Arizona, Inc. overturned 54.04% of the 1,462 internal appeals its Arizona members filed against 740,183 denials, and the Arizona escalation count for UnitedHealthcare of Arizona, Inc. 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, UnitedHealthcare of Arizona, Inc.'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 UnitedHealthcare of Arizona, Inc. 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 UnitedHealthcare of Arizona, Inc. in Arizona. One payment. No subscription. No cut of your claim.
UnitedHealthcare of Arizona, Inc. inside Arizona
Your denial did not happen in a national average. It happened in a state market, alongside 6 other insurers reporting into the same federal file, and these are that market's own figures.
- Across the whole of Arizona, the 7 insurers reporting in this file processed 8,988,391 in-network claims and denied 1,449,189 of them, a state denial rate of 16.1%. UnitedHealthcare of Arizona, Inc. is one of those 7.
- That puts Arizona 16th of 29 states by denial rate, 0.4 points above the 15.7% national average, before you get to what UnitedHealthcare of Arizona, Inc. did inside it.
- Arizona recorded 11,145 internal appeals against those denials: one appeal for every 130 claims the state's insurers refused. UnitedHealthcare of Arizona, Inc.'s own ratio is one for every 506.
- Independent external review was reached 294 times in the whole of Arizona, once for every 4,929 denials, against one in 17,061 nationally. How many came from UnitedHealthcare of Arizona, Inc.'s denials is not on the record, that is the Arizona figure this page names as absent at the top and sources at the foot.
- Of the Arizona external reviews that were filed, 61 were overturned, 20.7%. That percentage is measured on 294 reviews, which is why the count beside it matters more than the rate does when you are deciding whether to file against UnitedHealthcare of Arizona, Inc..
- The reason Arizona's insurers record most often is other reasons, 653,458 claims, 33.9% of the state's categorized denials. UnitedHealthcare of Arizona, Inc. records the same one most often, so your letter is likely to say it too.
- The other insurers an Arizona reader could have bought from run from 50.1% (Imperial Insurance Companies, Inc.) to 9.5% (Antidote Health Plan of Arizona, Inc.). UnitedHealthcare of Arizona, Inc. at 24.5% sits between the two.
- Put the two together and UnitedHealthcare of Arizona, Inc. is responsible for 51.1% of every in-network claim denied in Arizona in this release, from 33.6% of the claims the state's insurers processed.
- Every Arizona figure in this section is that state's own row in the same federal file UnitedHealthcare of Arizona, Inc.'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 Arizona page is free at /states/arizona.

Who appeals what at UnitedHealthcare
UnitedHealthcare runs a mandatory TWO-STEP provider process, a claim reconsideration first, an appeal only after, and is strict about who counts as the member's representative. The first row is the member's route; the others are the provider's. From UnitedHealthcare's published pages, written for health care providers and members; each is listed below with its date. It is brand-level and applies to UnitedHealthcare of Arizona, Inc. in Arizona the same as to every other UnitedHealthcare entity in the file.
| Dispute | Route |
|---|---|
| A plan denial you want changed (member) | Member, authorized representative or contracted provider. The member form says a timely request; federal rules generally give at least 180 days |
| Post-service claim dispute (provider) | Reconsideration first, then appeal, both steps inside 12 months |
| Pre-service denial | Appeal 'made prior to a planned health care service'; expedited available if delay could seriously jeopardize the member |
| Provider appealing on the member's behalf | Requires authorization/patient consent, an assignment of benefits is NOT enough |
Operational facts from the same policy
- Combined window for both steps: 12 months , One clock covers both steps — a slow reconsideration eats the appeal window.
- Two-step structure is mandatory: reconsideration, then appeal
- Assignment of benefits is not representation: separate patient consent needed , For patients: your provider billing UnitedHealthcare for you does NOT automatically let them appeal AS you — a separate authorization is needed, or you appeal yourself.
- Submission is portal/API: UnitedHealthcare Provider Portal or API , No mailing address or fax is published on this page.
- Expedited appeal is pre-service only: not available after the service
- Peer-to-peer review windows: 3 business days inpatient / 21 calendar days outpatient
- Member grievance window (California section of the form): 180 calendar days , Member-side second source. This wording sits under the form's California grievance instructions, so it is not a national appeal deadline. UnitedHealthcare's provider page publishes no member window.
- Who may appeal (member side): member, authorized representative, or contracted provider
- Member review clocks: acknowledge 5 days, decide 30 days standard / 3 days urgent , Stated on a form page that also carries California-specific sections (DMHC 1-888-466-2219, Independent Medical Review) — plan-state specifics can vary.

The UnitedHealthcare of Arizona, Inc. figures on this page, the 24.5% denial rate, the 740,183 denials, are this issuer’s own reported rows in that file. CMS did not report an external-review figure for UnitedHealthcare of Arizona, Inc. in Arizona in the plan-year 2027 release of the Transparency in Coverage file, which is why no external-review count appears above.
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. 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).
