Notwithstanding any other provision of law, and except as provided under this section, any person, other than an insurance company duly licensed in this or another state which provides coverage in this state for medical, surgical, chiropractic, physical therapy, speech pathology, audiology, professional mental health, dental, hospital, or optometric expenses, whether such coverage is by direct payment, reimbursement, or otherwise, is presumed to be subject to the jurisdiction of the commissioner unless the person shows that while providing such services the person is subject to the jurisdiction of another agency of this state, any subdivisions thereof, or the federal government. A self-insurance health plan formed under chapter 54-52.1 is not subject to this section but is subject to the jurisdiction of the commissioner under chapter 26.1-36.6.
