United keeps denying my claims. I'm up to my ears in medical debt and I make close to nothing.
Those 131,081 denials are 3.7% of every in-network denial recorded in South Carolina in this release, which makes UnitedHealthcare of South Carolina, Inc. the 3rd largest source of denials of the 5 insurers reporting there. Spread across its 17 plans in the state that is about 7,711 denials per plan. 158 internal appeals were filed against those 131,081 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: 131,081 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 second highest at 19.1%. The highest in the state is 29.9% and the lowest is 11.5%.
- That is 3.4 percentage points above the 15.7% national average across this dataset, and 3.4 points above the South Carolina average of 15.7%.
- Behind the percentage: 684,686 in-network claims were processed under 17 plans in South Carolina, and 131,081 of them came back denied.
- For every 10,000 claims UnitedHealthcare of South Carolina, Inc. denied, about 12 came back as an internal appeal. The other 9,988 stopped at the letter.
- Of the internal appeals it did receive, UnitedHealthcare of South Carolina, Inc. overturned 27.85%, 44 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 22.2% (1,092 of 4,918; interval 22.2-23.8% for counts CMS withheld; 32.6% without SelectHealth) are overturned.
- Its most-recorded denial reason is other reasons at 38.1% 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 South Carolina, Inc. accounts for 3.7% of every in-network claim denied in South Carolina in this file.
- By raw volume it is the 76th largest source of denials among the 135 insurer-state records in the file that report one.
- After that, its second-most-recorded reason is provider out of network, 128,155 claims, 34% of its categorized denials.
- Third on its own list is member not covered, 42,695 claims, 11.3% of what UnitedHealthcare of South Carolina, Inc. categorized in South Carolina. Between them the top three account for 83.4% of its categorized denials.
- Where UnitedHealthcare of South Carolina, Inc. differs most from the national mix is provider out of network: 34% of its categorized denials in South Carolina against 9% across the file.
- Read the other way round: 553,605 of those 684,686 in-network claims were paid, 80.9% of everything UnitedHealthcare of South Carolina, Inc. processed in South Carolina.
- Spread across the 17 plans it reports in South Carolina, that is about 7,711 denied claims per plan, on about 40,276 claims processed per plan.
- Its reason columns add up to 377,190 categorized rows against 131,081 denials, 287.8% 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 not medically necessary, 13 claims, 0% of what UnitedHealthcare of South Carolina, Inc. categorized there.
- Against the file as a whole, this one record is 0.2% 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 South Carolina, Inc. records most often in South Carolina 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 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 27.85% of the internal appeals it did receive, 44 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 |
|---|---|---|
| UnitedHealthcare of South Carolina, Inc. | 19.1% | , |
| South Carolina average | 15.7% | +3.4 pts |
| National average (this dataset) | 15.7% | +3.4 pts |
UnitedHealthcare of South Carolina, Inc. denies 3.4 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 UnitedHealthcare of South Carolina, Inc.) | 158 | 27.85% |
| External review (independent) | 0 | not reported |
The gap nobody escalated
131,081 claims denied. 158 internal appeals filed. None reached independent external review. Nationally 22.2% (1,092 of 4,918; interval 22.2-23.8% for counts CMS withheld; 32.6% without SelectHealth) 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 UnitedHealthcare of South Carolina, Inc. letter, and by when. UnitedHealthcare of South Carolina, Inc. overturned 27.85% of the 158 internal appeals its South Carolina members filed against 131,081 denials, and not one of those South Carolina denials went on to the independent stage whose decision binds the plan, UnitedHealthcare of South Carolina, 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 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.

- The reason South Carolina's insurers record most often is other reasons, 1,320,114 claims, 29.6% of the state's categorized denials. UnitedHealthcare of South Carolina, Inc. records the same one most often, so your letter is likely to say it too.
- The other insurers a South Carolina reader could have bought from run from 29.9% (Select Health of South Carolina) to 11.5% (Absolute Total Care, Inc). UnitedHealthcare of South Carolina, Inc. at 19.1% sits between the two.

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 South Carolina, Inc. in South Carolina 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.

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).
