Note: In 2014, Medicare spent about $21 billion on approximately 46 million administrations of Part B drugs paid based on average sales price (ASP). We defined expenditures as the total amount spent by the Medicare fee-for-service program and its beneficiaries, and administrations as the number of claim line items for a drug. Both measures included only those for claim line items that Medicare paid based on ASP. The figure includes all provider specialties that accounted for at least 3 percent of expenditures or administrations on Part B ASP drugs.
