Injectafer denied for missing prior authorization by Blue Cross Blue Shield?

Q: How long do I have to appeal a Blue Cross Blue Shield Injectafer denial?

Internal appeal window: Typically 180 days from the denial date. External review window: Typically 60–120 days after the final internal denial. The clock starts from the date on the denial letter.

If the original prescription wasn't run through prior auth, the path is to submit a PA now with a medical-necessity letter — many plans then back-date approval to the date of service.

US health-plan appeal rights

Cite: Most US health plans have appeal rights under either the ACA, ERISA, or Medicare/Medicaid rules

Most US health plans are required by federal law to give you both an internal appeal (where the insurer reconsiders) and an external review (where an independent reviewer decides). The exact timelines and processes depend on what kind of plan you have — marketplace / employer group, self-funded, Medicare Advantage, or Medicaid MCO — but in every case there's a window after the denial during which you have the right to fight it.

What Blue Cross Blue Shield typically requires

HFrEF / HFmrEF with iron deficiency (ferritin <100 OR 100-299 with TSAT <20%) to improve symptoms and reduce HF hospitalizations.

What works in the appeal

ESC 2021 HF Guidelines (McDonagh Eur Heart J 2021;42:3599) — Class IIa for IV FCM in HFrEF iron def. Ferritin <100 OR 100-299 + TSAT <20% IS iron deficient in HF context. FAIR-HF NEJM 2009 + CONFIRM-HF Eur Heart J 2015 + AFFIRM-AHF Lancet 2020 + HEART-FID NEJM 2023. Oral iron does NOT improve HFrEF outcomes (IRONOUT-HF JAMA 2017 negative).
