PMHNP Practice Authority in Kentucky: Independence, Physician Agreements and Schedule II

AANP's May 2026 map puts Kentucky in its reduced tier.

The label is AANP's advocacy classification; the legal fact behind it is that Kentucky splits prescribing into two agreements.

Before prescribing nonscheduled legend drugs, the APRN enters a written CAPA-NS with a physician licensed in Kentucky; before prescribing Schedules II through V, a written CAPA-CS on a standardized form, also with a Kentucky-licensed physician.

The agreements govern prescribing only — the APRN licence itself comes from the Board of Nursing, and practice decisions outside prescriptions do not require either agreement.

For a PMHNP the practical reading is that the physician relationship follows the prescription pad, in two pieces with different exit rules.

Kentucky's statutes build an exit from both agreements onto a four-year clock — the route AANP's reduced label does not show.

For legend drugs: after four years of prescribing as a nurse practitioner, clinical nurse specialist, nurse midwife or nurse anesthetist — for NPs and CNSs the four years must be in a population focus — an APRN in good standing notifies the board and stops needing the CAPA-NS; there is no review step, and the agreement may be kept voluntarily.

If the licence is not in good standing, the CAPA-NS stays until it is restored.

For controlled substances the exit is gated: four years of controlled-substance prescribing with a CAPA-CS, a maintained DEA registration and a maintained KASPER master account earn only the right to request board review, with a fee due whether or not the exemption is granted.

Both agreements are with a Kentucky-licensed physician qualified in the same or a similar specialty; the board judges that from the facts and the scope of each party's actual practice.

For an APRN who has not had a CAPA-CS, a CAPA-CS in the first year of licensure requires employment by a health care entity or provider; an APRN employer must hold the four-year exemption.

Meetings run at least quarterly in the first CAPA-CS year, then at least biannually, in person or by video, reviewing the APRN's reverse KASPER report.

Records are kept one year past expiry; each board audits its own licensee's records.

A CAPA-CS is rescinded on thirty (30) days written notice; a CAPA-NS on written notice alone.

If an agreement ends unexpectedly for reasons outside the APRN's control, the rule allows thirty (30) days of continued prescribing with documented per-patient justification, not extendable or successive — but the violations section ties the grace period to legend drugs only, so confirm controlled-substance prescribing with the board.

No ratio cap appears in the sources read.

The schedule limits decide psychiatric prescribing.

Every APRN Schedule II prescription is limited to a 72-hour supply without any refill, except hydrocodone combination products at a 30-day supply without refill.

Psychostimulants may be written for a 30-day supply only by an APRN certified in psychiatric-mental health nursing providing services in a KRS Chapter 216B health facility or a KRS Chapter 210 regional mental-health or intellectual-disability program.

An APRN outside those settings is held to the 72-hour, no-refill Schedule II supply, and whether a given outpatient clinic qualifies as a KRS 216B health facility is not defined in the sources read — confirm with the board.

Schedule III is capped at a 30-day supply without refill; Schedules IV-V at the original prescription plus refills up to a six-month supply.

APRNs may prescribe but not dispense Schedules II-V, and a CAPA-CS may impose stricter limits.

The rule adds workflow: a PDMP query at least once every three months per patient, and the federal 90-day split-prescription mechanism (21 CFR 1306.12(b)) does not apply to Kentucky APRNs.

Before prescribing controlled substances, the APRN holds a DEA Controlled Substance Registration Certificate, reports the Kentucky DEA number and any status change to the board within thirty days of issuance, and registers for a PDMP master account within thirty days of the DEA certificate and before prescribing.

At an initial controlled-substance prescribing decision, an APRN certified in psychiatric-mental health must obtain a medical and psychiatric history, perform a mental health assessment and document both.

No separate state controlled-substance registration was located in the sources read — the DEA registration and the KASPER master account are the layers the rule names.

Federally, the DEA registers the PMHNP as a mid-level practitioner, and that registration covers only what Kentucky allows.

The DEA and HHS telemedicine flexibilities, extended through December 31, 2026, remove the federal in-person-visit requirement but lift no Kentucky limit — the CAPA-CS and the schedule caps bind telehealth prescriptions the same as in-person ones.

Kentucky has not enacted the APRN Compact.

The compact comes into effect only once seven states enact it, and five had as of September 2026 — Delaware, North Dakota, South Dakota, Utah and Wyoming — so no APRN holds a multistate APRN licence today.

The Nurse Licensure Compact is an RN compact and confers no nurse practitioner authority in another state.

To practise as a PMHNP in Kentucky you need a Kentucky APRN licence and, until the four-year exemptions land, the CAPA-NS and CAPA-CS agreements.

June 29, 2023 amendments to KRS 314.042 built the current CAPA-CS structure — the standardized form developed by a joint committee of the two boards, the first-year employment rule, the at-least-quarterly-then-biannual KASPER meetings and the four-year exemption — but the enacting bill number is not located in the text read.

201 KAR 20:057 was amended effective March 21, 2024 and February 13, 2025 (filed with the Legislative Research Commission on January 13, 2025).

One caution the sources flag: the KAR cites the CAPA-CS provisions and the exemption by subsection numbers that do not match the FindLaw statute text, so this page cites the rules by content, not subsection number.

The FindLaw statute text is as of January 1, 2025, and 2025-2026 session amendments were not checked.

Endorsement applicants get their own path onto the same four-year standard.

A CAPA-NS is not required for an APRN who met the prescribing requirements in a state that grants independent prescribing and has at least four years of prescribing, or who had a collaborative prescribing agreement with a physician in another state for at least four years.

Controlled substances run parallel: four years of controlled-substance prescriptive authority in a state that grants it, plus a licence in good standing under the review standard, exempts.

With fewer than four years, the rule sends the mover into a Kentucky CAPA-CS until the cumulative four-year mark, then the exemption request — so a mid-career relocation resets the clock to whatever remains, not to zero.
