What Aetna's policy requires for iv iron infusion
Cited policy: Aetna CPB — Monoferric (Ferric Derisomaltose) PA
Adults with IDA intolerant of or unresponsive to oral iron. Up to 20 mg/kg single dose (max 1000 mg).
How Aetna denies iv iron infusion — and how to counter it
Where Aetna pushes back: 1) Single-dose experimental; 2) Use Venofer or Feraheme cheaper; 3) Insufficient oral iron trial.
Counter-arguments that hold up: Monoferric FDA-approved Jan 16, 2020 — NOT experimental. Pivotal FERWON-IDA / FERWON-NEPHRO (Auerbach Am J Hematol 2019). On-label single-dose 1000 mg in one sitting reduces visits, infusion chair time, nursing time vs Venofer (5-10 visits to replete 1g). Total cost of care favors single-dose for working-age and low-access patients.
