Summary

Berinert (human c1-esterase inhibitor) may be considered medically necessary for hereditary angioedema when all of the listed diagnosis, medication review and specialist criteria are met. Cinryze (human c1-esterase inhibitor), Kalbitor (ecallantide), Ruconest (recombinant c1-esterase inhibitor) and Takhzyro (lanadelumab-flyo) are considered not medically necessary because other formulary alternatives are covered for both acute and prophylactic treatment of HAE attacks. The 04/01/2026 revision set Berinert quantity limits of 20 units/kg per infusion, up to 2 doses per 30 days, changed the initial approval length from 6 months to 12 months, and updated the renewal criteria.
