Employer hiring guide
PC owner vs. medical director: which do you need?
A PC owner holds an ownership interest in a professional entity. A medical director leads defined clinical work. A CMO provides broader executive medical leadership. Your organization may need more than one function, and titles alone do not establish the right structure.

Compare the three functions
When the need is physician ownership
An MSO may need an eligible physician owner for the clinical entity under the applicable state structure. The arrangement must preserve the authority required by law. Hiring a medical director does not by itself satisfy professional ownership requirements.
- Have counsel identify the permitted entity and owners.
- Review the complete control and succession arrangements.
- Define the work the owner will actually perform.
When the need is clinical or executive leadership
A medical director role usually centers on a clinical program, service or operational function. A CMO role often spans broader strategy and leadership. In a small company, responsibilities may overlap; define the decisions, duties and accountability before selecting the title.
- Specify whether the physician treats patients or prescribes.
- Identify any program-specific medical director qualifications.
- Match specialty and sector experience to your services.
- Set hours, coverage, reporting lines and measurable objectives.
When one physician may perform multiple roles
A physician may perform ownership and leadership functions when qualified and permitted. Document each function distinctly. Combining titles does not eliminate licensing, independence, compensation, insurance or coverage requirements.
- Separate ownership documents from the scope of clinical work.
- Allocate compensation and responsibilities clearly.
- Review conflicts, time capacity and succession with advisers.
Resources for verification
Use the relevant state licensing boards to verify licenses and disciplinary information. FSMB’s state board directory links to those boards. For applicable exclusions screening, consult the HHS OIG exclusions resources.
For California ownership and clinical-control questions, read the California CPOM guide with legislative and enforcement sources and the Medical Board’s practice guidance. These hiring guides are general information; your advisers should assess your specific structure and obligations.
