Collaborative Practice Agreement for Psychiatric Mental Health Nurse Practitioners in Maryland

Not unconditionally. Maryland does not name a specific instrument.

Practice authorityConditional independence
Written agreementNo agreement required
What Maryland calls itNo named instrument
Research date2026-09-03

PMHNPs follow the same 2015 Full Practice Authority Act framework as any other NP population focus (Health Occ. § 8-508; COMAR 10.27.07). This entry exists for its own page/URL/calculator weight, not a legal distinction from `np`.

Independent practice requires: Same 18-month first-time-NP mentorship as general NPs — see that entry; Maryland's Nurse Practice Act doesn't set a separate threshold for the psychiatric-mental-health population focus..

What the collaboration must look like

The rules the physician relationship has to follow. Each fact comes from the statute or board rule listed under sources.

Proximity

first-time NP (never certified in any state) during the 18-month mentorship: Available remotely (no on-site requirement)

Same mentorship standard as general NPs.

after the 18-month mentorship, or any NP already certified in another state: No proximity requirement

No physician availability/proximity standard applies once independent.

Supervision ratio

Not codified — no cap on file

Chart review

Not codified — left to the agreement

Meeting cadence

Not codified — left to the agreement

Prescriptive authority

Covered by the practice agreement · controlled substances permitted

Same statutory scope as general NPs (Schedule II-V). PMHNP prescribing in practice skews toward Schedule II stimulants and Schedule IV benzodiazepines/hypnotics more heavily than general primary-care NP prescribing — not a different legal limit, reflected in calculatorWeights below.

Written agreement

Not required

Same as general NP — no written agreement required at any point.

Practice ownership (corporate practice of medicine)

Licensee-only ownership required — Same as the general `np` entry — open item given Maryland's physician-only PC regime and non-recognition of PLLCs.

About Maryland's rules

Maryland's APRN categories are NOT uniform: CRNPs/CNMs gained full practice authority in 2015 (after an 18-month new-graduate mentorship), but CRNAs remain fully supervised with NO prescriptive authority at all (Maryland is one of ~11 states granting CRNAs none), and only the psychiatric-mental-health population focus of CNS practice is independent. Maryland does not recognize PLLCs — professional entities use physician-only Professional Corporations, so multi-disciplinary PC ownership questions are open items below.
