Date Posted: Tuesday,

To determine the dosage, size, doses per package and how many billing units are in each package, refer to the NDC number.
Take a look at the following
J1071 - Injection, testosterone cypionate, 1mg
For example; using NCD # 0009-0085-10 there are 10 doses of 100 mL
(100 mg/mL = 1 mL and there are 10 ml in each vial, and 1 vial in each package), therefore, if each dose is 100 mL, you would bill 10 units to report 1000 mg.

Notice how the NDC indicates the doses per package with the last two numbers
