Policy note: This is a short-term CMS demonstration program operating outside of Medicare Part D plan coverage, launching July 1, 2026. Only Zepbound KwikPen is covered; the single-dose pen and vials are explicitly excluded. The document notes that patients with moderate-to-severe sleep apnea must submit to their Part D plan and are NOT eligible for Bridge — therefore Zepbound's OSA indication is not covered under this program. The program uses a central processor for PA, claims processing, and pharmacy payment. PA request is pharmacy-initiated. Only 28-day or 30-day fills are covered. A new PA is required only if a patient switches from one covered GLP-1 to another.
