Understanding MSOs
If you're exploring ownership of a medical spa, dermatology practice, wellness clinic, or other healthcare business, you've likely encountered the term "MSO."
An MSO, or Management Services Organization, is a business structure commonly used to help healthcare practices comply with Corporate Practice of Medicine (CPOM) laws while allowing non-physicians to participate in the business side of a practice.
The MSO model can be an effective tool when properly structured. It can also create significant legal risk when implemented incorrectly.
At Marti Law Group, we regularly help physicians, nurse practitioners, entrepreneurs, investors, and practice owners evaluate whether an MSO structure makes sense for their business goals. We also help clients design and document MSO arrangements that comply with state laws while preserving appropriate separation between clinical and business functions.
Here, we answer common questions about MSOs.

MSO FAQs
1 / What is an MSO?
A Management Services Organization (MSO) is a company that provides non-clinical administrative and management services to a healthcare practice. Depending on state law and the specific arrangement, an MSO may provide services such as: Marketing and advertising Human resources and payroll administration Office management Accounting and bookkeeping Equipment procurement Leasing and facilities management Technology and software support Scheduling and administrative services The MSO does not provide medical care. Instead, it supports the operations of the healthcare practice through a contractual management services arrangement.
2 / Why do many medical spas use an MSO structure?
Many medical spas operate in states that have restrictions on who can own or control a medical practice. Because many aesthetic treatments are considered the practice of medicine, medical spa owners often need to navigate complex regulatory requirements concerning ownership, management, and clinical oversight. An MSO structure can help create a legal framework that separates clinical functions from business operations. In a properly structured arrangement, licensed healthcare professionals retain authority over patient care and clinical decisions, while the MSO manages certain administrative and operational functions. This approach can allow entrepreneurs, investors, and non-clinical business professionals to participate in the business side of a medical spa while respecting applicable healthcare laws.
3 / What is the Corporate Practice of Medicine?
Corporate Practice of Medicine (CPOM) refers to a legal doctrine that limits the ability of non-licensed individuals or business entities to own, control, or influence medical practices. The purpose of CPOM laws is to protect independent clinical judgment and ensure that medical decisions are made based on patient care rather than business interests. CPOM rules vary significantly from state to state. Some states have strict restrictions, while others take a more permissive approach. Understanding your state's CPOM requirements is often the first step in determining whether an MSO structure may be appropriate for your business.
4 / How do I know if I need an MSO?
Whether an MSO is necessary depends on several factors, including your state's laws, the services your business provides, who owns the business, and how clinical care is delivered. There is no one-size-fits-all answer. Businesses that involve physician supervision, medical treatments, outside investors, or non-physician ownership interests often benefit from a legal review to determine whether an MSO structure should be considered. In some cases, an MSO may be an important compliance tool. In others, it may be unnecessary. The key is evaluating the specific facts of your business rather than assuming that every medical spa requires the same structure.
5 / Who is responsible for making clinical decisions in a properly structured MSO?
Clinical decisions should be made by appropriately licensed healthcare professionals. This includes decisions regarding patient evaluations, diagnoses, treatment plans, medical necessity, supervision requirements, and other aspects of patient care. While an MSO may assist with administrative operations, it should not direct or influence clinical judgment. The healthcare practice and its licensed providers remain responsible for medical decision-making and patient care. Maintaining a clear separation between business operations and clinical authority is one of the most important aspects of a compliant MSO.
6 / How does fee splitting work?
Fee splitting laws are designed to prevent healthcare providers from improperly sharing professional fees with unlicensed individuals or entities. Because these laws vary by state, compensation arrangements involving medical practices and MSOs must be carefully structured. In many MSO arrangements, the healthcare practice pays the MSO for management and administrative services. However, not every compensation model is permissible in every state. Arrangements that directly tie compensation to medical revenue or patient services may raise regulatory concerns depending on the jurisdiction. Because fee splitting rules are highly state-specific, it is important to evaluate both the structure of the business and the compensation arrangement before implementing an MSO model. A structure that works in one state may create compliance issues in another.
7 / Is an MSO required for every medical aesthetics practice?
No. While MSOs are common in the medical spa industry, they are not required in every situation. Whether an MSO is necessary depends on the state's laws, the services being offered, the ownership structure, and the overall business model. Some businesses can operate compliantly without an MSO, while others may require one to address Corporate Practice of Medicine concerns or ownership restrictions. The decision should be based on a careful legal analysis rather than industry trends or assumptions.
8 / What documents will I need for an MSO structure?
A properly structured MSO arrangement typically involves more than a single management agreement. Depending on the circumstances, the structure may include a Management Services Agreement, practice ownership documents, employment agreements, independent contractor agreements, medical director agreements, corporate governance documents, and compliance policies. The specific documents will vary based on the business model and applicable state law. Regulators often evaluate not only how a business is organized on paper, but also how it operates in practice. For that reason, both the documentation and the day-to-day relationship between the MSO and healthcare practice should align with applicable legal requirements.
