Maine: Ownership and Oversight
FPA after 24 supervised months plus a model modern PA Act. Maine gives NPs independence after a two-year on-ramp with unusually flexible supervision options, and its 2020 PA act is one of the cleanest in the country: a 4,000-hour threshold with a credentialing-system substitute for facility-based PAs.
Who the Statute Actually Covers
- NP transition (32 M.R.S. § 2102; Board rules ch. 8): before independent practice and prescribing, a CNP practices at least 24 months under the supervision of a licensed physician or a supervising NP, or is employed by a clinic or hospital with a physician medical director; written evidence to the Board of Nursing on completion, then full independence with Schedule II–V prescribing (DEA registration).
- PA collaborative agreement (32 M.R.S. § 3270-G): a PA with fewer than 4,000 documented clinical hours works under a collaborative agreement with an active physician describing scope and team decision-making — except a PA in a physician group practice or health care facility may substitute the facility's credentialing and privileging system plus a scope of practice agreement. At 4,000+ hours, practice is governed at the practice level; a PA may provide any service they are prepared for by education, training, and experience.
- Dispensing: PAs dispense only where pharmacy service is not reasonably available, in the patient's best interest, or in an emergency (§ 3270-G(3)).
1. Who Can Own What
| Entity / Path | Who May Own | Key Limits |
|---|---|---|
| Professional entities | Licensee-owned professional corporations under the Maine Professional Service Corporation Act (13 M.R.S. ch. 22-A) when that form is used. | Verify combinations with Maine counsel. |
| NP-owned practice | Fully viable after the 24-month on-ramp; the supervising-NP and medical-director alternatives make the on-ramp itself easy to structure inside an NP-led organization. | Maine defines NPs as primary care providers and mandates insurer coverage of NP services. |
| PA-owned practice | Feasible for experienced PAs given the 4,000-hour structure; sub-threshold PA owners keep collaborative agreements in place. | — |
| Lay / MSO | Standard exclusion from professional entities; MSO at FMV. | — |
2. Collaborative and Supervisory Oversight
| Role | Agreement Required | Oversight Mechanics | Path to Independence |
|---|---|---|---|
| PA | Under 4,000 hours: collaborative agreement with an active physician (or facility credentialing-plus-scope substitute). Over 4,000 hours: practice-level governance, no mandated agreement. | No ratio; no statutory chart-review percentage; decision-making processes live in the agreement or credentialing documents. | Yes — 4,000 documented clinical hours end the mandatory collaborative agreement (32 M.R.S. § 3270-G(5)). |
| NP | First 24 months: supervision by a licensed physician OR a supervising NP, or employment at a facility with a physician medical director; written evidence to the Board on completion. | No ratio; no chart-review percentage; supervision mechanics are relationship-defined. | Yes — 24 months, then fully independent practice and Schedule II–V prescribing (32 M.R.S. § 2102). |
3. Primary Authorities
- 32 M.R.S. § 2102; Me. Board of Nursing rules (02-380 ch. 8) (24-month supervised period; prescribing).
- 32 M.R.S. § 3270-G (PA collaborative agreements; 4,000-hour threshold; facility substitute; dispensing).
- 13 M.R.S. ch. 22-A (professional service corporations).
Practical read: Maine's on-ramp is the friendliest in New England because the supervisor doesn't have to be a physician — an NP-led group can grow entirely on supervising NPs, and a new graduate hired by any clinic with a physician medical director satisfies the requirement by employment alone. On the PA side, the facility credentialing substitute means hospital PAs may never sign a collaborative agreement at all; keep that distinction straight when auditing Maine files.
