Insurance got denied, what to do next?
Those 385,536 denials are 85.8% of every in-network denial recorded in Delaware in this release, which makes Highmark BCBSD Inc. the 1st largest source of denials of the 2 insurers reporting there. Spread across its 20 plans in the state that is about 19,277 denials per plan. 158 internal appeals were filed against those 385,536 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 Delaware 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: 385,536 in-network claims were denied by Highmark BCBSD Inc. in Delaware 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 2 insurers reporting a denial rate in Delaware, Highmark BCBSD Inc. is the second highest at 19.3%. The highest in the state is 29.3% and the lowest is 19.3%.
- That is 3.6 percentage points above the 15.7% national average across this dataset, and 1 points below the Delaware average of 20.3%.
- Behind the percentage: 1,993,680 in-network claims were processed under 20 plans in Delaware, and 385,536 of them came back denied.

- Its most-recorded denial reason is other reasons at 81.2% 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.
- Highmark BCBSD Inc. accounts for 85.8% of every in-network claim denied in Delaware in this file.
- By raw volume it is the 44th largest source of denials among the 135 insurer-state records in the file that report one.
- After that, its second-most-recorded reason is member not covered, 15,520 claims, 6.8% of its categorized denials.

- Where Highmark BCBSD Inc. differs most from the national mix is other reasons: 81.2% of its categorized denials in Delaware against 32.4% across the file.
- Read the other way round: 1,608,144 of those 1,993,680 in-network claims were paid, 80.7% of everything Highmark BCBSD Inc. processed in Delaware.
- Spread across the 20 plans it reports in Delaware, that is about 19,277 denied claims per plan, on about 99,684 claims processed per plan.
- Its reason columns add up to 228,322 categorized rows against 385,536 denials, 59.2% 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 Delaware is administrative reason, 52 claims, 0% of what Highmark BCBSD Inc. categorized there.
- Against the file as a whole, this one record is 0.5% 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 Highmark BCBSD Inc. records most often in Delaware 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 Highmark BCBSD Inc. in Delaware 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. Highmark BCBSD Inc. overturned 43.67% of the internal appeals it did receive, 69 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.

| Delaware average | 20.3% | -1 pts |
| National average (this dataset) | 15.7% | +3.6 pts |
Highmark BCBSD Inc. denies 3.6 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 Highmark BCBSD Inc.) | 158 | 43.67% |
| External review (independent) | not reported | not reported |
What that record means for your own Highmark BCBSD Inc. letter, and by when. Highmark BCBSD Inc. overturned 43.67% of the 158 internal appeals its Delaware members filed against 385,536 denials, and the Delaware escalation count for Highmark BCBSD 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, Highmark BCBSD 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 Highmark BCBSD 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 Highmark BCBSD Inc. in Delaware. One payment. No subscription. No cut of your claim.
Highmark BCBSD Inc. inside Delaware

- That puts Delaware third of 29 states by denial rate, 4.6 points above the 15.7% national average, before you get to what Highmark BCBSD Inc. did inside it.
- Delaware recorded 237 internal appeals against those denials: one appeal for every 1,896 claims the state's insurers refused. Highmark BCBSD Inc.'s own ratio is one for every 2,440.

- The reason Delaware's insurers record most often is other reasons, 192,134 claims, 67.6% of the state's categorized denials. Highmark BCBSD Inc. records the same one most often, so your letter is likely to say it too.
- The other insurers a Delaware reader could have bought from run from 29.3% (AmeriHealth Caritas VIP Next, Inc.) to 29.3% (AmeriHealth Caritas VIP Next, Inc.). Highmark BCBSD Inc. at 19.3% sits below all of them.

The Highmark BCBSD Inc. figures on this page, the 19.3% denial rate, the 385,536 denials, are this issuer’s own reported rows in that file. CMS did not report an external-review figure for Highmark BCBSD Inc. in Delaware 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).
