This section applies to each self-funded group insurance plan that: is formed by an order, society, or association that is incorporated or has a main office in the State; or covers individuals who reside or work in the State; and is issued, renewed, amended, or reissued on or after July 1, 1972. Notwithstanding any other provision of a self-funded group insurance plan subject to this section, if the plan provides for reimbursement for a service that is within the lawful scope of practice of a physician, dentist, or podiatrist, the plan may not prohibit a person covered by the plan from being reimbursed for the service regardless of whether the service is performed by a physician, dentist, or podiatrist.
