In New Jersey, NPs generally need a collaborating physician rather than a “supervising” physician. To prescribe medications and devices, an APN must have a written joint protocol with a physician unless the APN qualifies for independent practice authority beginning March 30, 2026123.
The joint protocol must be in writing, signed by both parties, maintained at each practice site, updated as practice changes occur, and reviewed at least annually45. Collaboration is defined in regulation as an ongoing process by which an APN and a physician engage in practice within agreed-upon parameters1.
