Informational only, not legal advice. Requirements change, so verify with the Massachusetts Board of Registration in Nursing and the AANP State Practice Environment map. Last reviewed: July 2026. This page focuses on PMHNPs but reflects general nurse practitioner rules in Massachusetts, which change over time, so confirm your specific situation with the board.
Practice Authority
Massachusetts Practice-Authority Category (Full Practice)
The American Association of Nurse Practitioners (AANP) currently classifies Massachusetts as a full practice state. In a full practice environment, a PMHNP may generally evaluate and diagnose patients, order and interpret tests, and initiate and manage treatment, including prescribing, under the exclusive licensure authority of the state board of nursing, without a mandated physician agreement. Because these designations can change, confirm the current category directly with the Massachusetts Board of Registration in Nursing and the AANP map before you rely on it.
Collaboration
Is a Collaborative or Supervisory Agreement Required?
Because Massachusetts is a full practice authority state, it generally does not mandate a collaborative or supervisory physician agreement for nurse practitioner practice. Individual employers, facilities, or payers may still request specific documentation. What any agreement must contain, how it is documented, and how often it is reviewed are set by state rule and can change, so confirm the current requirements and forms with the Massachusetts Board of Registration in Nursing.
Prescriptive Authority
Prescriptive Authority and Controlled Substances
Massachusetts nurse practitioners who meet the state’s requirements may be granted prescriptive authority, which in general can extend to controlled substances when the appropriate conditions are met. Controlled-substance prescribing also requires a separate federal DEA registration, and some substances carry additional conditions. Because the specific scope and documentation are governed by state law and board rule, verify current details with the Massachusetts Board of Registration in Nursing and the U.S. Drug Enforcement Administration before prescribing.
Next Step
Credentialing Is a Separate Track
Scope of practice decides how you can practice in Massachusetts. Getting paid is a separate track, with its own payer rules, Medicaid program, and enrollment timelines. We cover that in detail on the Massachusetts credentialing and payer enrollment page, and nationally in our PMHNP credentialing guide.
