PMHNP Practice Requirements in Maryland: Scope, Prescribing & Collaboration
If you are a psychiatric mental health nurse practitioner (PMHNP) planning to practice in Maryland, here is a plain-language overview of the state’s practice-authority category, any collaboration required, and how those rules shape your billing and credentialing. General information, not legal advice.
Please Read First
Informational only, not legal advice. Requirements change, so verify with the Maryland Board of Nursing and the AANP State Practice Environment map. Last reviewed: July 2026. This page focuses on PMHNPs but reflects general nurse practitioner rules in Maryland, which change over time, so confirm your specific situation with the board.
Practice Authority
Maryland Practice-Authority Category (Full Practice)
The American Association of Nurse Practitioners (AANP) currently classifies Maryland 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 Maryland Board of Nursing and the AANP map before you rely on it.
Collaboration
Is a Collaborative or Supervisory Agreement Required?
Because Maryland 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 Maryland Board of Nursing.
Prescriptive Authority
Prescriptive Authority and Controlled Substances
Maryland 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 Maryland Board of Nursing and the U.S. Drug Enforcement Administration before prescribing.
Billing and Credentialing
What This Means for Your Billing and Credentialing
Your practice-authority category in Maryland affects how you enroll with payers, how your claims are attributed, and what documentation a health plan asks for during credentialing. Because Maryland is a full practice environment, you can often enroll and be credentialed under your own authority, though payers still verify licensure, DEA, and specialty. Getting this right up front prevents denied claims and delayed enrollments later.
FAQ
Frequently Asked Questions
Is Maryland a full practice authority state for PMHNPs?

Do I need a collaborating or supervising physician in Maryland?
In a full practice authority state, generally no state-mandated physician agreement is required, but verify with the Maryland Board of Nursing. Employers and payers may still set their own requirements.
Can a PMHNP prescribe controlled substances in Maryland?
NPs who meet state requirements may be granted prescriptive authority that can include controlled substances, but a separate DEA registration is required and conditions apply. Verify with the Maryland Board of Nursing and the DEA.
