The DEA number of a physician's assistant must start with which letter?

The DEA number of a physician's assistant must start with the letter M. This designation is specifically assigned to mid-level practitioners, which includes physician assistants, nurse practitioners, and other similar healthcare providers who are authorized to prescribe controlled substances.

Each category of prescribers has a designated starting letter for their DEA numbers. For example, the letter A is typically used for hospitals and practitioners. However, the letter M is unique to mid-level practitioners to distinguish their prescribing authority and ensure proper identification within the regulations governing controlled substances. This system helps in tracking and managing the prescribing practices of various healthcare providers effectively.

Understanding the significance of the starting letter in DEA numbers is crucial for anyone involved in pharmacy practice, as it aids in recognizing the qualifications of the prescriber and ensuring compliance with federal regulations.
