Year by year

Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.

This is pharmacy cost, not the office bill, and not what patients paid.

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
