Insurance got denied, what to do next?
Those 1,323,501 denials are 29% of every in-network denial recorded in Tennessee in this release, which makes BlueCross BlueShield of Tennessee the 2nd largest source of denials of the 5 insurers reporting there. Spread across its 96 plans in the state that is about 13,786 denials per plan. 587 internal appeals were filed against those 1,323,501 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 Tennessee 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.

The BlueCross BlueShield of Tennessee figures on this page, the 21.1% denial rate, the 1,323,501 denials, are this issuer’s own reported rows in that file. CMS did not report an external-review figure for BlueCross BlueShield of Tennessee in Tennessee 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.

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).
