A Michigan NP needs a DEA registration to prescribe controlled substances. Under Michigan law, an APRN may prescribe controlled substances only when a physician delegates this authority via a written authorization, and any controlled-substance prescription must include both the APRN’s and the physician’s names and DEA registration numbers12.
The required written authorization must include the physician’s and APRN’s names, license numbers, signatures, any limitations or exceptions, and the effective date, and it must be reviewed and noted annually by the delegating physician34. For complimentary starter dose controlled substances, delegation is required, and both the APRN’s and physician’s names and DEA registration numbers must be indicated5.
A delegating physician may also authorize multiple prescriptions totaling up to a 90-day supply of Schedule II controlled substances6. These provisions underscore that an NP (APRN) must hold a DEA registration and have physician delegation in place to prescribe controlled substances in Michigan.
