Drug prices are per billing unit (the unit is in the code's name, such as "per 10 mg"). Your dose decides how many units you're billed, so the total depends on your prescription, and giving the drug may be billed separately.

Original Medicare amounts are only for people on original Medicare. Your share depends on your plan’s deductible, copay and coinsurance.
