Wisconsin Practice Structure Guide: The Service Corporation, a Strict Attorney General Opinion and the Fee-Splitting Statute

Entity and Ownership

Wisconsin's service corporation subchapter allows one or more licensed persons to form a service corporation if all hold the same license or are all health care professionals, a term that covers licensees of more than fifteen boards including the Medical Examining Board and the Board of Nursing, so physician and nurse practitioner or physician assistant co-ownership is permitted. Each shareholder, director and officer must be licensed in the same field or be a health care professional, and an unlicensed person may not have any part in ownership or control and cannot hold a proxy. Articles are filed with the Department of Financial Institutions, the name must end in chartered, limited, service corporation, ltd. or S.C., and an annual report certifies that all shareholders, directors and officers are licensed. An S.C. may not engage in business other than what it was organized for, and professionals remain personally liable for their own malpractice and for acts of those under their supervision. The physician practice act also recognizes bona fide physician partnerships. Wisconsin's S.C. is not a tax S corporation, and we found no statute authorizing a physician LLC.

The Corporate Practice Position

The practice act prohibits any person from practicing medicine and surgery without a license, and the general definitions treat corporations as persons. A 1986 Attorney General opinion concluded that a for-profit business corporation may not employ physicians to render medical services and that receiving fees for the employed physician's services violates the fee-splitting and licensure statutes. The opinion treats service corporations as outside that analysis. A 2015 State Bar paper identifies three statutory exceptions, partnerships and service corporations, hospitals and nonprofit medical education and research organizations, and says there are no published Wisconsin cases on the doctrine, that guidance is mainly Attorney General opinions and that enforcement is not rigorous. We did not find later appellate decisions, though our search was not exhaustive. A physician violating the practice subchapter may be fined up to $25,000 or imprisoned up to nine months.

The Management Agreement and Fees

The fee-splitting statute provides that no licensee may give or receive, directly or indirectly, any fee, commission, rebate or other compensation or anything of value for sending, referring or otherwise inducing a person to communicate with a licensee in a professional capacity, or for any professional services not actually rendered personally or at the licensee's direction. The Attorney General's 1986 opinion reads it to catch a corporation that collects a physician's fees while the physician gets patients through it. Board rule Med 10.03 makes it unprofessional conduct to use illegal or unethical business practices or to give or receive compensation for services not actually and personally rendered while preserving lawful professional corporations, and it covers false advertising and inadequate supervision of delegated acts. A statute also requires separate bills from each practitioner, with a service corporation exception allowing a single bill that identifies each rendering licensee.

We found no Wisconsin authority approving or banning percentage fees. A percentage fee to an unlicensed management company that also markets or refers patients is the highest-risk pattern, and a fixed, fair-market fee for administrative services is the conservative design. That is our analysis and not a stated rule. Non-competes follow a general reasonableness test, and a 2026 bill that would make physician non-competes unenforceable after two years had a hearing in January, but we could not confirm its fate. We found no enacted transaction notice law.

Med Spa and Delegation Rules

Wisconsin has no med spa registration or license that we found. A person providing patient services as directed, supervised and inspected by a physician who has the power to direct, decide and oversee the services is outside the unlicensed practice prohibition, and Board rules define adequate supervision by the physician's competence and reasonable evidence of the supervised person's competence. The Cosmetology Examining Board's rule lets licensees provide delegated medical procedures such as laser hair removal and microneedling only as directed, supervised and inspected by a physician under formal written protocols. Together those rules make a remote paper medical director risky, which is our inference. A 2025 act creates an APRN license effective September 1, 2026, with a path to independent practice, but an independent APRN still could not be owned or controlled by a lay management company if the entity must be a service corporation.

How We Structure It

As a rule we set up a service corporation owned by the licensed physician, with no exceptions for what looks like a more flexible state. Patients pay the physician-owned practice. The practice pays the management company a fixed monthly fee under a written management services agreement. The management company pays MedGrid a fixed monthly retainer for consulting. The MSO never practices medicine, and the physician makes every clinical decision. In Wisconsin the management company never collects or touches professional fees except as a flat payment for defined non-clinical services, and it takes no part in ownership or control.
