Typically, the letter M on a DEA number pertains to which type of provider?

• A. Doctors
• B. Pharmacists
• C. Mid-level providers
• D. Hospitals

Answer: (C)

The first letter on a DEA registration identifies the category of prescriber. M is used for mid-level practitioners, such as nurse practitioners, physician assistants, and certified nurse-midwives. That’s why this prefix signals mid-level providers. Knowing this helps you recognize who can prescribe controlled substances under their DEA registration and how their authority often works under state rules or supervisory protocols. Other provider types (like physicians or hospitals) use different prefixes, and while pharmacists can hold DEA registrations, the M designation specifically points to mid-level practitioners.
