United keeps denying my claims. I'm up to my ears in medical debt and I make close to nothing.
We hear this most. r/HealthInsurance, thread title, read September 3, 2026.
The number nobody else publishes, and here it is missing. CMS publishes no external-review figure for UnitedHealthcare of South Carolina, Inc. in South Carolina, so nobody, including the regulator, can say whether anyone ever got that far. We print no number rather than reading an absence as a zero. Nationally, 5,881 of 84,502,749 denials reached that stage, one in every 14,369, and 32.8% of those were overturned.

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.

The clock your letter has to describe, in actual dates

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.

What to do tonight
  1. 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.
  2. 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.
  3. 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.

None of those three steps costs anything. Anyone charging you to do them is selling you something you can do yourself in twenty minutes.

UnitedHealthcare of South Carolina, Inc. denies 1.4 percentage points more of its in-network claims than the national average across this dataset.

Read the table for what it is: the external-review row above shows a dash, which means not reported and not zero, the South Carolina absence this page states once at the top for UnitedHealthcare of South Carolina, Inc. and sources once at the foot. External review is free to you and the insurer must follow the decision, whatever this file does or does not record about it.

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.

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 denialYour provider
Provider appealing on the member's behalfYour provider
How to use this: if your scenario says "health care provider appeal", the move is a call to your provider's billing office asking them to appeal, not a letter from you. If it says "Either", a provider-led appeal and your own member appeal can run together. Your member rights under federal law, generally 180 days for the internal appeal, then external review, apply regardless of this table, and regardless of which of the 6 insurers reporting in South Carolina sent your letter.

Where these numbers come from

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).

This page presents federal statistics and a general description of appeal rights created by federal law. It is not legal, medical, or insurance advice, and no outcome is guaranteed. Your denial letter and plan documents govern your specific case. Free help is available from your state's Consumer Assistance Program and from the federal Marketplace at HealthCare.gov.
Problem solved: You have both dates for your UnitedHealthcare of South Carolina, Inc. notice, you know that South Carolina runs the external review itself, and you have the letter, free, on this screen, tonight.
