The terminology for physician involvement in NP prescriptive authority spans a continuum including on-site physician supervision, professional collaboration, collaboration with agreed upon protocols or delegation, or no involvement whatsoever.

Twelve states and the District of Columbia have the most independent prescribing procedure: no requirement for physician involvement (including controlled substances schedules II through V):

Alaska
Arizona
District of Columbia
Idaho
Iowa
Maine (after first 2 years of supervised practice)
Montana
New Hampshire
New Mexico
Oregon
Washington
Wisconsin (if NP is certified as an "advanced practice nurse prescriber")
Wyoming
