No independent-practice pathway exists — a PA must always practice under a licensed physician relationship. After ~3 years under physician supervision, the statute's language shifts from 'supervision' to 'collaboration' with a physician (§ 61-6C-8, NMSA), which loosens day-to-day involvement but does not remove the physician relationship itself.

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

Available remotely (no on-site requirement)

16.10.15 NMAC: collaboration/supervision 'shall not be construed to require the physical presence of the licensed physician at the time and place services are rendered' — effective supervision requires 'on-going availability of direct communication, either face-to-face or by electronic means,' with a means for immediate communication. No mile/minute radius is codified.

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

May prescribe Schedule II–V controlled substances under physician supervision/collaboration and an established PA-patient relationship (Controlled Substances Act; PAs are defined as 'practitioners'); requires state controlled-substance registration and DEA registration. No schedule-specific day-supply cap was found in this research pass.

Written agreement

Required

Practice ownership (corporate practice of medicine)

Licensee-only ownership required — New Mexico professional corporations must be owned entirely by licensees of the same profession — a PA-owned PC cannot include physician co-owners, and a physician-owned PC cannot include a PA. New Mexico has no CPOM doctrine restricting non-licensee employment of physicians generally (1987 A.G. opinion), but the professional-corporation single-profession rule is a separate, narrower restriction.

Whether a PA can independently own a single-profession PA-only PC (as opposed to needing a physician-owned entity to practice through) was not confirmed — treat as an open item.

About New Mexico's rules

New Mexico has no corporate-practice-of-medicine doctrine (1987 A.G. opinion) — non-physician entities may employ physicians if clinical judgment isn't controlled — but professional corporations must still be single-profession owned (a PA/NP/etc. entity can't mix ownership with physicians). NP/CRNA/CNM/CNS practice independently with full prescriptive authority (Schedules II–V); PA remains the outlier requiring ongoing physician involvement.
