Tarlatamab

Medicare

Part B (clinician-administered)

Given by infusion or injection in a clinic or hospital outpatient department, so it is a Part B drug: Medicare pays 80% after the Part B deductible and the patient owes 20% coinsurance, uncapped in Original Medicare unless a Medigap policy applies. Step-up dosing is often started in hospital (Part A) because of cytokine release syndrome monitoring, then continued in the outpatient setting. First DLL3 engager for small-cell lung cancer (2024).

Commercial insurance

covered with prior authorisation

Covered under the medical benefit with prior authorisation confirming diagnosis, biomarker status and line of therapy; site-of-care policies may steer infusions away from hospital outpatient departments.

20% Part B coinsurance on a high-cost infusion adds up quickly: Medigap Plan G or N, Medicare Advantage maximum out-of-pocket, Medicaid dual eligibility, or a charity fund are the usual buffers.
