As of January 1, 2023, Medicare Part D plans require the use of e-prescribing for all controlled substance prescriptions.

• A. Yes
• B. No
• C. Only for C-II
• D. Only for outpatient prescriptions

Answer: (A)

Electronic prescribing for all controlled-substance prescriptions under Medicare Part D is required starting January 1, 2023. This mandate covers every controlled substance (CII–CV) written for Part D beneficiaries, not just a subset or only certain settings. The purpose is to enhance safety and reduce fraud by ensuring prescriptions are transmitted electronically and can be checked against monitoring programs in real time. Because the requirement is broad and applies to all controlled substances, the best answer is Yes. The other options don’t fit because the rule isn’t limited to a specific schedule or to outpatient prescriptions only.
