Research date2026-09-03

PMHNPs follow the same 32 M.R.S. § 2102 framework as any other NP population focus. This entry exists for its own page/URL/calculator weight, not a legal distinction from `np`.

Independent practice requires: Same 24-month supervised-practice pathway as general NPs — see that entry; Maine's APRN statute 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

during the 24-month supervised period: Available remotely (no on-site requirement)

Same standard as general NPs.

after 24 months of supervised practice: No proximity requirement

No physician/supervisor availability 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, reflected in calculatorWeights below.

Written agreement

Not required

Same as general NP — only a registered supervisory relationship, no written agreement, during the 24-month period.

Practice ownership (corporate practice of medicine)

Licensee-only ownership required — Same as the general `np` entry — probable but unverified NP-owned entity pathway once independent.

About Maine's rules

Maine's provider categories follow different independence models: NPs graduate to full practice after 24 months of registered (not written-agreement) supervision; PAs graduate after 4,000 documented clinical hours but still need a lighter 'practice agreement' afterward; CNMs/CNSs appear independent from initial licensure; and CRNAs remain physician/dentist-accountable except in critical-access/rural hospitals. Do not assume a single APRN framework applies uniformly.
