Insurance got denied, what to do next?
Those 219,509 denials are 68% of every in-network denial recorded in Montana in this release, which makes Blue Cross and Blue Shield of Montana the 1st largest source of denials of the 2 insurers reporting there. Spread across its 60 plans in the state that is about 3,658 denials per plan. 392 internal appeals were filed against those 219,509 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 Montana 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: 219,509 in-network claims were denied by Blue Cross and Blue Shield of Montana in Montana in a single plan year.

- Its reason columns add up to 280,080 categorized rows against 219,509 denials, 127.6% of them, and every reason share on this page is a share of that first figure rather than of the second.

- Find the reason code on your denial letter. The reason Blue Cross and Blue Shield of Montana records most often in Montana 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.

What that record means for your own Blue Cross and Blue Shield of Montana letter, and by when. Blue Cross and Blue Shield of Montana overturned 24.49% of the 392 internal appeals its Montana members filed against 219,509 denials, and the Montana escalation count for Blue Cross and Blue Shield of Montana 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, Blue Cross and Blue Shield of Montana'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 Blue Cross and Blue Shield of Montana 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 Blue Cross and Blue Shield of Montana in Montana. One payment. No subscription. No cut of your claim.

The Blue Cross and Blue Shield of Montana figures on this page, the 13.1% denial rate, the 219,509 denials, are this issuer’s own reported rows in that file. CMS did not report an external-review figure for Blue Cross and Blue Shield of Montana in Montana 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.
