Insurance got denied, what to do next?
Those 17,786 denials are 0.5% of every in-network denial recorded in South Carolina in this release, which makes InStil Health Insurance Company the 5th largest source of denials of the 5 insurers reporting there. Spread across its 4 plans in the state that is about 4,447 denials per plan. 61 internal appeals were filed against those 17,786 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: 17,786 in-network claims were denied by InStil Health Insurance Company 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, InStil Health Insurance Company is the fourth highest at 16.5%. The highest in the state is 29.9% and the lowest is 11.5%.
- That is 0.8 percentage points above the 15.7% national average across this dataset, and 0.8 points above the South Carolina average of 15.7%.
- Behind the percentage: 107,654 in-network claims were processed under 4 plans in South Carolina, and 17,786 of them came back denied.
- For every 10,000 claims InStil Health Insurance Company denied, about 34 came back as an internal appeal. The other 9,966 stopped at the letter.
- Of the internal appeals it did receive, InStil Health Insurance Company overturned 40.98%, 25 claims that started life as a no.
- Its most-recorded denial reason is administrative reason at 24.1% of its categorized denials, against 17.2% nationally, a heavier share than the country as a whole. That is the denial mix, not an outcome rate.
- InStil Health Insurance Company accounts for 0.5% of every in-network claim denied in South Carolina in this file.
- By raw volume it is the 120th largest source of denials among the 135 insurer-state records in the file that report one.
- After that, its second-most-recorded reason is other reasons, 5,580 claims, 19.9% of its categorized denials.

- Where InStil Health Insurance Company differs most from the national mix is not medically necessary: 13% of its categorized denials in South Carolina against 5.5% across the file.
- Read the other way round: 89,868 of those 107,654 in-network claims were paid, 83.5% of everything InStil Health Insurance Company processed in South Carolina.
- Spread across the 4 plans it reports in South Carolina, that is about 4,447 denied claims per plan, on about 26,914 claims processed per plan.
- Its reason columns add up to 28,057 categorized rows against 17,786 denials, 157.7% 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 member not covered, 1,602 claims, 5.7% of what InStil Health Insurance Company categorized there.
- Against the file as a whole, this one record is 0% 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 InStil Health Insurance Company records most often in South Carolina is administrative reason, 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 InStil Health Insurance Company 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. InStil Health Insurance Company overturned 40.98% of the internal appeals it did receive, 25 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.

| National average (this dataset) | 15.7% | +0.8 pts |
InStil Health Insurance Company denies 0.8 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 InStil Health Insurance Company) | 61 | 40.98% |

What that record means for your own InStil Health Insurance Company letter, and by when. InStil Health Insurance Company overturned 40.98% of the 61 internal appeals its South Carolina members filed against 17,786 denials, and the South Carolina escalation count for InStil Health Insurance Company 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, InStil Health Insurance Company'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 InStil Health Insurance Company 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 InStil Health Insurance Company in South Carolina. One payment. No subscription. No cut of your claim.
InStil Health Insurance Company 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 22,792,856 in-network claims and denied 3,573,275 of them, a state denial rate of 15.7%. InStil Health Insurance Company is one of those 6.
- That puts South Carolina 17th of 29 states by denial rate, 0 points above the 15.7% national average, before you get to what InStil Health Insurance Company did inside it.
- South Carolina recorded 5,791 internal appeals against those denials: one appeal for every 617 claims the state's insurers refused. InStil Health Insurance Company's own ratio is one for every 292.
- Independent external review was reached 261 times in the whole of South Carolina, once for every 13,691 denials, against one in 17,061 nationally. How many came from InStil Health Insurance Company'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, 144 were overturned, 55.2%. That percentage is measured on 261 reviews, which is why the count beside it matters more than the rate does when you are deciding whether to file against InStil Health Insurance Company.
- The reason South Carolina's insurers record most often is other reasons, 1,320,114 claims, 29.6% of the state's categorized denials. InStil Health Insurance Company records administrative reason 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 29.9% (Select Health of South Carolina) to 11.5% (Absolute Total Care, Inc). InStil Health Insurance Company at 16.5% sits between the two.
- Put the two together and InStil Health Insurance Company is responsible for 0.5% of every in-network claim denied in South Carolina in this release, from 0.5% 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 InStil Health Insurance Company'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 South Carolina page is free at /states/south-carolina.

The InStil Health Insurance Company figures on this page, the 16.5% denial rate, the 17,786 denials, are this issuer’s own reported rows in that file. CMS did not report an external-review figure for InStil Health Insurance Company in South Carolina 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).
