Massachusetts: Ownership and Oversight
Case-law CPOM + NP independence at 2 years (with NP supervisors). Massachusetts pairs an old case-law corporate practice doctrine with one of the most modern APRN frameworks in the country: independence after two supervised years, where the supervisor can itself be an experienced NP rather than a physician.
Who the statute actually covers
- CPOM source: case law (McMurdo v. Getter, 298 Mass. 363 (1937): corporation may not practice a profession through licensed employees) plus professional corporations under M.G.L. ch. 156A, licensee-owned, single profession. Hospitals and licensed clinics (ch. 111) supply the institutional employment lane.
- "Qualified Healthcare Professional" (QHP) (244 CMR 4.07): the supervisor of a new APRN's prescriptive practice; may be a physician board-certified (or with admitting privileges) in a related specialty, or a CNP/PNMHCS with independent practice authority meeting Board criteria. Massachusetts does not require a physician anywhere in the NP pipeline.
- Independence threshold (M.G.L. ch. 112, § 80E; Acts of 2020, ch. 260; 244 CMR 4.07): CNPs, PNMHCSs, and CRNAs with 2 years of supervised practice (or equivalent out-of-state) attest to the Board and prescribe with no supervision and no written guidelines; under 2 years, signed prescriptive guidelines kept in the workplace.
1. Who can own what
| Entity / Path | Who may own | Key limits |
|---|---|---|
| Medical PC | Physicians only under ch. 156A when the professional corporation form is used; McMurdo bars lay entities from practicing medicine through employed licensees. | Licensed facilities and HMOs are the exceptions. |
| NP-owned practice | Fully viable for independent NPs; needs no physician relationship at all, and an experienced NP owner can serve as QHP for junior NPs in the same practice. | One of the only states where an NP group can grow entirely on NP supervision. |
| PA path | No ownership lane; PAs practice under physician supervision (separate PA Board). | |
| Lay / MSO | Not permitted to practice medicine or control clinical judgment (McMurdo); MSO model standard at FMV. |
2. Collaborative and supervisory oversight
| Role | Agreement required | Oversight mechanics | Path to independence |
|---|---|---|---|
| PA | Physician supervision, continuous but not requiring personal presence (M.G.L. ch. 112, § 9E); written delegation covering prescriptive practice; MCSR + DEA for controlled substances. | No ratio: Massachusetts sets no limit on PAs per physician. One hard rule: every PA-issued Schedule II prescription must be reviewed by the supervising physician within 96 hours (263 CMR 5.06(3)). | None. PA supervision is career-long. |
| NP | Under 2 years: prescriptive practice under signed written guidelines with a QHP supervisor (physician or independent NP), kept at the workplace and producible to the Board. Over 2 years: attestation filed, then nothing. | No ratios or chart-review percentages; the guidelines define consultation and referral triggers. MCSR amended to reflect independent status. | Yes: 2 years of supervised practice (or out-of-state equivalent) ends supervision entirely (§ 80E; 244 CMR 4.07). CNMs follow a separate framework. |
3. Primary authorities
- McMurdo v. Getter, 298 Mass. 363 (1937); M.G.L. ch. 156A; ch. 111.
- M.G.L. ch. 112, § 80E; Acts of 2020, ch. 260, § 36; 244 CMR 4.07.
- M.G.L. ch. 112, § 9E; 263 CMR 5.04–5.06.
Practical read: The Massachusetts detail that changes business models is the QHP rule: a two-NP practice where the senior NP supervises the junior one is fully compliant with zero physician spend. The detail that trips audits is the PA 96-hour Schedule II review — a real clock with real documentation, and the one piece of MA PA supervision that cannot be delegated to a policy binder.
