UnitedHealthcare of Wisconsin, Inc. denied 113,541 of 659,260 in-network claims in Wisconsin; every one of those denials had these same two dates on it. Across Wisconsin as a whole the insurers in this file denied 12.1% of in-network claims, 1,188,325 of them, and 2,083 were appealed.
UnitedHealthcare of Wisconsin, Inc. denied 17.2% of in-network claims in Wisconsin, 113,541 claims out of 659,260.
United keeps denying my claims. I'm up to my ears in medical debt and I make close to nothing.
Those 113,541 denials are 9.6% of every in-network denial recorded in Wisconsin in this release, which makes UnitedHealthcare of Wisconsin, Inc. the 5th largest source of denials of the 12 insurers reporting there. Spread across its 13 plans in the state that is about 8,734 denials per plan. 594 internal appeals were filed against those 113,541 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 Wisconsin 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: 113,541 in-network claims were denied by UnitedHealthcare of Wisconsin, Inc. in Wisconsin 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 12 insurers reporting a denial rate in Wisconsin, UnitedHealthcare of Wisconsin, Inc. is the second highest at 17.2%. The highest in the state is 18.9% and the lowest is 6.5%.
- That is 1.5 percentage points below the 18.7% national average across this dataset, and 5.1 points above the Wisconsin average of 12.1%.
- Behind the percentage: 659,260 in-network claims were processed under 13 plans in Wisconsin, and 113,541 of them came back denied.

- Its most-recorded denial reason is provider out of network at 35% of its categorized denials, against 9.8% nationally, a heavier share than the country as a whole. That is the denial mix, not an outcome rate.

- Spread across the 13 plans it reports in Wisconsin, that is about 8,734 denied claims per plan, on about 50,712 claims processed per plan.
- Its reason columns add up to 77,622 categorized rows against 113,541 denials, 68.4% 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 Wisconsin is administrative reason, 3,437 claims, 4.4% of what UnitedHealthcare of Wisconsin, Inc. categorized there.
- Against the file as a whole, this one record is 0.1% 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 UnitedHealthcare of Wisconsin, Inc. records most often in Wisconsin is provider out of network, 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 Wisconsin, Inc. in Wisconsin 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.

How that compares
| Denial rate | Rate | Difference |
|---|---|---|

| Wisconsin average | 12.1% | +5.1 pts |
| National average (this dataset) | 18.7% | -1.5 pts |

What happened to appeals
| Stage | Filed | Overturned |
|---|---|---|
| Internal appeal (to UnitedHealthcare of Wisconsin, Inc.) | 594 | 41.08% |

What that record means for your own UnitedHealthcare of Wisconsin, Inc. letter, and by when. UnitedHealthcare of Wisconsin, Inc. overturned 41.08% of the 594 internal appeals its Wisconsin members filed against 113,541 denials, and the Wisconsin escalation count for UnitedHealthcare of Wisconsin, 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 Wisconsin, Inc.'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 UnitedHealthcare of Wisconsin, 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 Wisconsin, Inc. in Wisconsin. One payment. No subscription. No cut of your claim.
UnitedHealthcare of Wisconsin, Inc. inside Wisconsin
Your denial did not happen in a national average. It happened in a state market, alongside 11 other insurers reporting into the same federal file, and these are that market's own figures.
- Across the whole of Wisconsin, the 12 insurers reporting in this file processed 9,824,576 in-network claims and denied 1,188,325 of them, a state denial rate of 12.1%. UnitedHealthcare of Wisconsin, Inc. is one of those 12.
- That puts Wisconsin 25th of 30 states by denial rate, 6.6 points below the 18.7% national average, before you get to what UnitedHealthcare of Wisconsin, Inc. did inside it.
- Wisconsin recorded 2,083 internal appeals against those denials: one appeal for every 570 claims the state's insurers refused. UnitedHealthcare of Wisconsin, Inc.'s own ratio is one for every 191.
- Not one denial in Wisconsin reached independent external review in the reported year, not UnitedHealthcare of Wisconsin, Inc.'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 Wisconsin's insurers record most often is other reasons, 363,275 claims, 39.5% of the state's categorized denials. UnitedHealthcare of Wisconsin, Inc. records provider out of network most often instead, which is the argument your letter will need to answer.
- The other insurers a Wisconsin reader could have bought from run from 18.9% (Security Health Plan of Wisconsin, Inc.) to 6.5% (HealthPartners Insurance Company). UnitedHealthcare of Wisconsin, Inc. at 17.2% sits between the two.
- Put the two together and UnitedHealthcare of Wisconsin, Inc. is responsible for 9.6% of every in-network claim denied in Wisconsin in this release, from 6.7% of the claims the state's insurers processed.
- Every Wisconsin figure in this section is that state's own row in the same federal file UnitedHealthcare of Wisconsin, Inc.'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 Wisconsin page is free at /states/wisconsin.

Who appeals what at UnitedHealthcare, the insurer's own routing table
UnitedHealthcare publishes a table of which denial scenarios are appealed by you, the member ("customer appeal") and which only your health care provider can appeal. Almost no patient ever sees it, and appealing a denial that only your provider has standing to appeal burns time inside a fixed window. Quoted from UnitedHealthcare's published policy (a page written for health care providers), checked 2026-08-25. It is brand-level and applies to UnitedHealthcare of Wisconsin, Inc. in Wisconsin the same as to every other UnitedHealthcare entity in the file.
| Denial scenario (UnitedHealthcare's wording) | Who appeals it |
|---|---|
| Post-service claim dispute (provider) | Your provider |
| Pre-service denial | Your provider |
| Provider appealing on the member's behalf | Your provider |
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 filing window: 180 calendar days , Member-side second source. UnitedHealthcare's provider page publishes no member window; this member form states 180 days.
- 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 Wisconsin, Inc. figures on this page, the 17.2% denial rate, the 113,541 denials, are this issuer’s own reported rows in that file. CMS did not report an external-review figure for UnitedHealthcare of Wisconsin, Inc. in Wisconsin in the plan-year 2026 release of the Transparency in Coverage file, which is why no external-review count appears above.
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).
