MSO vs Professional Medical Corporation: What are the Differences?

MSO vs Professional Medical Corp: Comparison Chart

Here’s a comparison chart outlining the differences between a Management Services Organization (MSO) and a Professional Medical Corporation:

MSO vs Professional Medical Corp: Comparison Chart

What is MSO?

The MSO model separates business operations from clinical services within a healthcare venture. This separation allows for consolidating administrative and marketing functions in one entity.

At the same time, clinical services are provided by healthcare professionals such as physicians, psychologists, and nurses in another entity.


MSOs facilitate collaborations between individuals with varying expertise, enabling the delivery of specialized healthcare services, whether it’s men’s health, women’s health, pediatric care, or addressing addictions.

Key Points:

  • MSOs create ventures where ownership is divided between business and clinical entities.
  • Fair market value (FMV) is pivotal in determining the compensation structure within MSO agreements.
  • Valuation experts may be consulted to ensure compliance with FMV standards.

What is a California Professional Corporation Medical?

Professional Medical Corporations (PCs) operate under specific legal frameworks, such as California’s Moscone-Knox Professional Corporation Act.

PCs allow licensed clinicians to establish entities where clinicians can serve as shareholders, directors, and employees.

This legal structure enables clinicians to mix and match ownership arrangements, incorporating individuals with diverse professional backgrounds into the corporation.

Key Points:

  • PCs offer flexibility in shareholder composition, allowing clinicians to involve individuals beyond the healthcare sector, such as family members or professionals from other industries.
  • Integrating MSO agreements with PC structures can lead to complex ownership arrangements, requiring careful legal navigation.

In-Depth Discussion of the Differences between MSO vs Professional Medical Corp


MSOs are typically owned by investors or non-medical professionals who may have expertise in business management but lack medical qualifications.

This ownership structure often reflects a strategic investment approach, where individuals or entities see potential returns in providing support services to healthcare practices.

On the other hand, Professional Medical Corporations are owned by licensed medical professionals with medical expertise and legal authority to deliver professional practice patient care directly.

This ownership model ensures that medical decisions are made by qualified practitioners who understand the clinical implications of their actions.

Services Provided by MSOS & Pro Med Corp

MSOs primarily offer management and administrative support to healthcare practices. This includes billing, staffing, IT support, and marketing services aimed at improving the efficiency and effectiveness of the practice’s operations.

In contrast, Professional Medical Corporations focus on providing direct medical care to patients. This encompasses the diagnosis, treatment, and preventive care services of various medical specialties.

The distinction lies in the services rendered, with MSOs concentrating on the business side of healthcare and Professional Medical Corporations delivering clinical care.

Legal Issues

MSOs operate as separate entities from the medical practices they serve. They function as medical  corporation and a management service providers, offering support services to healthcare practices under contractual agreements.

This separation helps delineate the roles and responsibilities of each party and may offer certain legal protections to the MSO and the medical practice.

In contrast, Professional Medical Corporations operate as legal entities directly involved in delivering medical services. They are subject to specific medical practice regulations, including licensure requirements and compliance with healthcare laws and standards.


In terms of liability, MSOs typically have limited liability for the non-clinical functions they perform. This means that they may not be held directly responsible for medical malpractice or negligence arising from the clinical activities of the healthcare practice.

However, practitioners within Professional Medical Corporations bear individual liability for their medical services. This includes potential legal consequences for errors or omissions in diagnosis, treatment, or patient care, emphasizing the importance of adhering to professional standards and best practices.


MSOs are primarily regulated for the management services they provide in healthcare settings. This regulation encompasses various aspects, such as compliance with healthcare privacy laws (e.g., HIPAA) and regulations governing financial relationships in healthcare (e.g., Stark Law).

On the other hand, Professional Medical Corporation is subject to regulations specifically related to medical practice. This includes licensing requirements for healthcare providers, adherence to medical standards of care, and compliance with laws governing the practice of medicine.

Revenue Model

The revenue model differs between MSOs and Professional Medical Corporations. MSOs typically generate revenue through service fees charged to the healthcare practices they serve. These fees may be based on a percentage of the practice’s income or a flat rate for specific services.

Professional Medical Corporations earn revenue directly from patients through fees for providing medical services rendered and insurance reimbursements for covered services.

This revenue model reflects the fundamental difference in their services, with MSOs providing support services for a fee and Professional Medical Corporations delivering billable medical care.


MSOs exercise control over non-clinical aspects of healthcare practices, focusing on optimizing business operations and administrative functions. This may include staffing, technology implementation, and financial management decisions.

Professional Medical Corporations control medical decisions, including diagnosis, treatment plans, and patient care protocols. This ensures that clinical decisions are made by qualified medical professionals based on their expertise and judgment.

Scope of Services

The scope of services offered by MSOs primarily revolves around streamlining business operations and enhancing efficiency within healthcare practices. This may involve implementing software systems for electronic health records, optimizing revenue cycle management processes, and providing human resources support.

Professional Medical Corporations offer a wide range of direct patient care services tailored to meet the healthcare needs of their patients. This includes diagnostic procedures, medical treatments, surgical interventions, and ongoing management of chronic conditions, among others.

Professional Expertise

MSO’s are typically staffed by business professionals with management, finance, and healthcare administration expertise. Their focus is on providing specialized support services to healthcare practices, leveraging their knowledge and skills in business management to optimize practice operations.

Professional medical corporations comprise licensed medical professionals with expertise in various healthcare specialties.

Their training and experience enable them to provide high-quality medical care, utilizing evidence-based practices and clinical guidelines to diagnose and treat patients effectively.


MSOs collaborate with healthcare providers to enhance operational efficiency and compliance with regulatory requirements. This may involve working closely with practice managers, physicians, and other stakeholders to identify areas for improvement and implement solutions to address them.

Collaboration within Professional Medical Corporations typically occurs internally among licensed medical professionals. This interdisciplinary collaboration ensures comprehensive patient care, with practitioners coordinating their efforts to deliver integrated medical services across different specialties and disciplines.


The comparison between MSO and Professional Medical Corp highlights the intricate legal landscape within the healthcare industry.

While MSOs offer administrative support and liability protection for non-clinical functions, Professional Medical Corporations directly provide patient care, subjecting practitioners to individual liability.

Understanding these legal nuances is essential for healthcare professionals, investors, and regulators as they navigate the complexities of delivering high-quality care while adhering to regulatory requirements and ensuring patient safety in an ever-changing healthcare landscape.
