Part B International Drug Pricing Model for Medicare Part B Drugs

The International Pricing Index (IPI) Model would initially focus on Part B single source drugs, biologicals, and biosimilars that encompass a high percentage of Part B drug utilization and spending. The CMS Innovation Center would test this model under section 1115A of the Social Security Act (the Act), which authorizes testing models expected to reduce program expenditures, while preserving or enhancing the quality of care furnished to beneficiaries. The model under consideration would include physicians, hospitals, and potentially other providers and suppliers in selected geographic areas.
