In short
- Part B covers only some drugs, like many shots and infusions.

Open Medicare.gov, Prescription drugs (outpatient), at https://www.medicare.gov/coverage/prescription-drugs-outpatient and read the part quoted above. Your own plan or policy papers hold details these sources do not give: "Don't know yet" for your case.
