A Michigan NP can prescribe controlled substances only when a physician delegates that authority via a written authorization; delegation may cover Schedules II–V1. By contrast, Michigan NPs may independently prescribe nonscheduled prescription drugs without physician delegation2.
The written authorization must include the names, license numbers, and signatures of both the physician and NP, any limitations, and the effective date3. The delegating physician must review and update this authorization annually, and must maintain it at the physician’s primary practice location and provide a copy to the NP45.
When an NP prescribes a controlled substance under delegation, both the NP’s and physician’s names and DEA registration numbers must be indicated on the prescription6. A physician may authorize multiple prescriptions totaling up to a 90-day supply of a Schedule II controlled substance7. Complimentary starter dose controlled substances also require delegation, with both parties’ names and DEA numbers recorded8.
