Over the past 3 years, as chronicled in several Proskauer alerts, an increasing number of states have sought to regulate physician practice management (“PPM”) and private equity transactions in the health care sector, including California, New York, Washington, and Illinois.
The regulation of health care transactions remains an evolving area of the law, drawing continued interest from state lawmakers and interest groups in a number of states.
Most recently, on June 9, 2025, Oregon Governor Tina Kotek signed S.B. 951 into law (“Oregon Law”), which imposes significant restrictions on the traditional PPM structure, pursuant to which a management services organization (“MSO”) enters into an exclusive and long-term management services arrangement (“MSA”) with a friendly physician-owned professional entity (“Friendly PC”). The Oregon Law is substantially similar to H.B. 4130, which was introduced and analyzed on this blog last year.
While other states have sought to regulate healthcare transactions primarily through transaction review mechanisms, Oregon’s Law takes a more aggressive approach by codifying direct restrictions on the corporate practice of medicine. The enactment of this law may prompt lawmakers in other states to adopt similar strategies—shifting from oversight of transactions to imposing substantive limitations on Friendly PC-MSO relationships.
The Oregon Law Contains a Number of Provisions That Target the PPM/Friendly PC Model
Subject to a few limited exceptions, the Oregon Law would materially impact the traditional PPM/Friendly PC model by strengthening and codifying new restrictions related to the corporate practice of medicine, largely contained in §1(2)(a) of the Oregon Law.
Certain MSOs Are Exempt from the Oregon Law’s Requirements
Notably, certain MSOs are exempt from the above requirements. For example, the restrictions do not apply to MSOs that are majority-controlled by the Friendly PC (See S.B. 951 § 1(3)(c)), MSOs that contract with telemedicine practices with no physical location in the state (See S.B. 951 § 1(4)(a)), hospital affiliates, behavioral health service providers or Program of All-Inclusive Care for the Elderly (“PACE”) organizations. See S.B. 951 § 1(3)(e).
The Oregon Law Includes a Blue Pencil Provision That Invalidates Non-Compliant MSA Terms
Last year’s proposed bill would have granted the Oregon Secretary of State the power to “administratively dissolve” a PC or limited liability company that violated the provisions of the bill. Such remedies, however, did not make their way into S.B. 951.
Instead, the Oregon Law, as enacted, contains a “blue pencil” provision that sets forth “a provision that authorizes or implements, or purports to authorize or implement, an act or practice that violates a prohibition set forth in subsection (2)(a) of this section is void and unenforceable.” See S.B. 951 § 1(5)(a).
The Oregon Law Imposes Restrictions on Non-Compete Agreements in the Healthcare Sector
Section 7 of the Oregon Law voids non-compete agreements that “restrict the practice of medicine” or the “practice of nursing.” See S.B. 951 § 7(2)(a). Although the Oregon Law contains certain exceptions, the exceptions appear designed to exclude non-competes utilized between an MSO and Friendly PC. For example, a non-compete may be entered into between a professional entity and a shareholder of the professional entity, provided that the professional entity “does not have a contract for management services with a management services organization.” See, e.g., S.B. 951 § 7(2)(b)(C)(i).
Effective Date and Applicability
The Oregon Law will take effect immediately, with the following effective dates for certain sections:
- January 1, 2026: MSOs and Friendly PCs formed on or after the Oregon Law’s effective date will become subject to Section 1 of the Oregon Law, which contains the Friendly PC / MSO restrictions.
- January 1, 2029: MSOs and Friendly PCs formed before the Oregon Law’s effective date will become subject to Section 1 of the Oregon Law, which contains the Friendly PC / MSO restrictions.
In addition, Sections 5, 7 and 8 of the Oregon Law (concerning restrictive covenants) will apply to “contracts that a person enters into or renews on and after the effective date [of the Oregon Law].” See S.B. 951 § 9. As such, although existing arrangements are grandfathered, contracts with evergreen or auto-renewal provisions may become subject to the new restrictions upon renewal.
