As of 2023, Medicare Part D plans require e-prescribing for all controlled substance prescriptions. Which claim is correct?

• A. All controlled substance prescriptions must be e-prescribed.
• B. Only C-II prescriptions must be e-prescribed.
• C. Only inpatient prescriptions must be e-prescribed.
• D. There is no requirement for e-prescribing.

Answer: (A)

The key idea is that Medicare Part D requires electronic prescribing for every prescription for a controlled substance. This mandate covers drugs in the controlled-substance schedules (C-II through C-V) and applies broadly, not just in one setting or for a single schedule. The goal is to standardize how these prescriptions are transmitted to pharmacies, which helps reduce fraud, improve safety, and support monitoring across Part D plans. Because of that, the claim that all controlled substance prescriptions must be e-prescribed is correct. The other options miss part of the scope by suggesting limits (only a specific schedule, or only inpatient) or nothing is required, which doesn’t reflect the universal requirement.
