UnitedHealthcare of South Carolina, Inc. denied 20.1% of in-network claims in South Carolina, 88,229 claims out of 438,616.
United keeps denying my claims. I'm up to my ears in medical debt and I make close to nothing.
Those 88,229 denials are 2.4% of every in-network denial recorded in South Carolina in this release, which makes UnitedHealthcare of South Carolina, Inc. the 4th largest source of denials of the 5 insurers reporting there. Spread across its 17 plans in the state that is about 5,190 denials per plan. 403 internal appeals were filed against those 88,229 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 South Carolina 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: 88,229 in-network claims were denied by UnitedHealthcare of South Carolina, Inc. in South Carolina 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 5 insurers reporting a denial rate in South Carolina, UnitedHealthcare of South Carolina, Inc. is the third highest at 20.1%. The highest in the state is 32.7% and the lowest is 15.5%.

- Spread across the 17 plans it reports in South Carolina, that is about 5,190 denied claims per plan, on about 25,801 claims processed per plan.
- Its reason columns add up to 55,937 categorized rows against 88,229 denials, 63.4% 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 South Carolina is administrative reason, 2,857 claims, 5.1% of what UnitedHealthcare of South Carolina, 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 South Carolina, Inc. records most often in South Carolina is service excluded from the plan, 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 South Carolina, Inc. in South Carolina 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 South Carolina, Inc. overturned 31.02% of the internal appeals it did receive, 125 claims, so the stage you are about to start is not decorative.

| National average (this dataset) | 18.7% | +1.4 pts |
UnitedHealthcare of South Carolina, Inc. denies 1.4 percentage points more of its in-network claims than the national average across this dataset.

What happened to appeals
| Stage | Filed | Overturned |
|---|---|---|
| Internal appeal (to UnitedHealthcare of South Carolina, Inc.) | 403 | 31.02% |

What that record means for your own UnitedHealthcare of South Carolina, Inc. letter, and by when. UnitedHealthcare of South Carolina, Inc. overturned 31.02% of the 403 internal appeals its South Carolina members filed against 88,229 denials, and the South Carolina escalation count for UnitedHealthcare of South Carolina, 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 South Carolina, 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 South Carolina, 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 South Carolina, Inc. in South Carolina. One payment. No subscription. No cut of your claim.
UnitedHealthcare of South Carolina, Inc. inside South Carolina
Your denial did not happen in a national average. It happened in a state market, alongside 5 other insurers reporting into the same federal file, and these are that market's own figures.
- Across the whole of South Carolina, the 6 insurers reporting in this file processed 21,454,469 in-network claims and denied 3,656,371 of them, a state denial rate of 17%. UnitedHealthcare of South Carolina, Inc. is one of those 6.
- That puts South Carolina 21th of 30 states by denial rate, 1.7 points below the 18.7% national average, before you get to what UnitedHealthcare of South Carolina, Inc. did inside it.
- South Carolina recorded 5,055 internal appeals against those denials: one appeal for every 723 claims the state's insurers refused. UnitedHealthcare of South Carolina, Inc.'s own ratio is one for every 219.
- Independent external review was reached 234 times in the whole of South Carolina, once for every 15,626 denials, against one in 14,369 nationally. How many came from UnitedHealthcare of South Carolina, Inc.'s denials is not on the record, that is the South Carolina figure this page names as absent at the top and sources at the foot.
- Of the South Carolina external reviews that were filed, 132 were overturned, 56.4%. That percentage is measured on 234 reviews, which is why the count beside it matters more than the rate does when you are deciding whether to file against UnitedHealthcare of South Carolina, Inc..
- The reason South Carolina's insurers record most often is other reasons, 992,225 claims, 24.5% of the state's categorized denials. UnitedHealthcare of South Carolina, Inc. records service excluded from the plan most often instead, which is the argument your letter will need to answer.
- The other insurers a South Carolina reader could have bought from run from 32.7% (Select Health of South Carolina) to 15.5% (Blue Cross and Blue Shield of South Carolina). UnitedHealthcare of South Carolina, Inc. at 20.1% sits between the two.
- Put the two together and UnitedHealthcare of South Carolina, Inc. is responsible for 2.4% of every in-network claim denied in South Carolina in this release, from 2% of the claims the state's insurers processed.
- Every South Carolina figure in this section is that state's own row in the same federal file UnitedHealthcare of South Carolina, 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 South Carolina page is free at /states/south-carolina.

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 South Carolina, Inc. in South Carolina 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 |

- 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.

- 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 South Carolina, Inc. figures on this page, the 20.1% denial rate, the 88,229 denials, are this issuer’s own reported rows in that file. CMS did not report an external-review figure for UnitedHealthcare of South Carolina, Inc. in South Carolina 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).
