What is the Osteopathic Medical Board of California?
The Osteopathic Medical Board of California (OMBC) is a state regulatory agency operating under the umbrella of the California Department of Consumer Affairs. It is the entity that licenses and regulates Doctors of Osteopathic Medicine (DOs).
The primary responsibility of the OMBC is to protect the public by establishing professional standards for Doctors of Osteopathic Medicine and enforcing these standards by passing regulations, investigating complaints and initiating disciplinary actions as needed to protect the public.
The OMBC’s votes on and enacts regulations governing the practice of medicine. These are codified in Title 16, Division 16 of the CCR ($1600 et seq.$). They focus on the following:
1. Licensure and Credentials
Educational Requirements: Setting standards for osteopathic medical school accreditation and postgraduate training (residency).
Continuing Medical Education (CME): Mandating 50 hours of CME every two years, including specific requirements for pain management and the treatment of terminally ill patients.
Examinations: Establishing the required scores and types of examinations (such as COMLEX-USA) for initial licensure.
2. Professional Standards & Scope of Practice
Supervision Ratios: Regulating how many Physician Assistants (PAs) a D.O. can supervise at one time.
Medical Assistants (MAs): Defining the technical supportive services an unlicensed MA can perform under supervision.
Aesthetic Procedures: Setting rules on who can perform laser treatments, Botox injections, and microdermabrasion.
RESPONSIBILITIES OF THE OMBC
The OMBC serves as the gatekeeper and "police" for osteopathic medicine in the state. Its duties are split into two main categories: Licensing and Enforcement.
1. Licensing and Credentials
Before a D.O. can treat a single patient in California, the OMBC must verify their qualifications. This includes:
Confirming graduation from an accredited osteopathic medical school.
Verifying at least one year of postgraduate training (residency).
Ensuring the passage of the COMLEX-USA or equivalent licensing exams.
Auditing Continuing Medical Education (CME) requirements every two years to ensure doctors stay current with medical advancements.
2. Enforcement and Public Protection
If a doctor fails to meet the standard of care, the OMBC has the authority to intervene. They handle:
Investigating Complaints: They review reports of gross negligence, unprofessional conduct, sexual misconduct, and substance abuse.
Disciplinary Action: The Board can issue fines, place a doctor on probation, or even revoke a medical license to protect the public.
Diversion Programs: They manage rehabilitation programs for physicians struggling with drug or alcohol impairment.
DIFFERENCES IN DISCIPLINE ARE UNFAIR AND IMPROPER
Despite having separate boards, both M.D.s and D.O.s are "complete physicians." They can prescribe medication, perform surgery, and practice in any specialty, from pediatrics to neurosurgery. The rules and regulations for both boards are very similar and they clearly coordinate substantially so that patient's treated by M.D.'s or D.O.'s have the same expectations of professionalism.
The landmark case in this area is D’Amico v. Board of Medical Examiners (1974). Following a 1962 merger attempt that tried to eliminate the Osteopathic Board, the California Supreme Court ruled that it was unconstitutional to deny DOs the right to be licensed simply because of their degree type.
The Ruling: The court established that MDs and DOs must be accorded equal professional status.
The Fairness Argument: If a law or board rule treats a DO differently than an MD without a "rational basis," it can be challenged as a violation of the Equal Protection Clause. Defense attorneys often use this precedent to argue that if the Medical Board allows a certain conduct, the Osteopathic Board cannot arbitrarily forbid it (and vice-versa).
2. The Diversion Program "Gap"
The most common modern complaint about unfairness involves the Physician Diversion Program.
Unfair to MDs? Some MDs have argued it is unfair that they are subjected to immediate public discipline for substance abuse issues, while their DO colleagues have access to a confidential rehabilitative path (the OMBC Diversion Program) that can protect their reputation and livelihood.
Unfair to the Public? Conversely, consumer advocates have occasionally argued that the DO board’s diversion program is "unfair to the public" because it lacks the transparency and strict enforcement found at the Medical Board.
Nurses have a disciplinary program as well. These discipline programs are often criticized for being very invasive and difficult to handle. But a loss of license or even a license with restrictions, ruins your relationship with employers, insurance carriers, state and federal payors and hospitals. The inconvenience when balanced strongly favors a diversion program.
The absence of an MBC program raises Equal Protection and Due Process issues. The boards are all under the same Department of Consumer Affairs, the Governor appoints both boards and the Attorney General's office represents both boards. The difference is simply unfair.
This creates the "Hero vs. Victim" Paradox: Legal commentators have noted that a physician could theoretically be treated as a "hero" (rehabilitated and supported) by one board and a "victim" (strictly disciplined) by the other for the same underlying conduct. Also since the same Deputy Attorneys General (DAGs) often prosecute cases for both boards, they sometimes face the awkward position of arguing for a specific penalty for an MD while knowing a DO would receive a different recommendation under OMBC guidelines. Defense attorneys frequently raise this "unequal application of the rules" during settlement negotiations.
4. Fictitious Business Names (FBN)
DOs have raised fairness concerns regarding the administrative burden of FBNs. The OMBC has historically been viewed as having more idiosyncratic or "manual" processes for approving practice names compared to the MBC. When a multi-specialty group includes both MDs and DOs, the conflicting requirements for how the practice must be named on letterheads and signs can create a "compliance trap" that feels arbitrary to the practitioners. This issue arises when a physician is in the cross hairs of a board - any violation will be used against him/her so board differences on minor matters can make a difference.
Summary of Arguments
| Argument Type | Basis of Unfairness |
| Equal Protection | "Same scope of practice should mean the same rules of conduct." |
| Due Process | "Lack of fair notice if one board permits what the other prohibits." |
| Public Policy | "A doctor's discipline should not depend on which board's political appointees are sitting that day." |
In legal defense, these discrepancies are often framed as "Underground Regulations" or arbitrary and capricious enforcement, especially when a board deviates from the standards set by its "sister" board without a clear medical justification.
In the right case a physician lawyer will compare rules and regulations between the two boards. If one board has a position slightly favorable to the practitioner there is a good argument that fundamental fairness requires the better rule to be applied. After all, the boards are separate but OD's and MD's are 100% equal. The same Department of Consumer Affairs sits on top of both boards. The same Attorney General's office supervises and staff both boards. The Governor appoints the members of both boards. In the right case this is "the right arguement to make". We make this point to emphasize that physician defense law is not cookie cutter (it can be in some cases but not in all).
