Subject to subsection (b) of this section, this coverage shall be the same as that provided under the health insurance plan for any other musculoskeletal disorder in the body and shall be covered when the diagnosis or treatment, or both, is prescribed or administered by a physician or a dentist.

1. (2) This section shall not be construed to require coverage for dental services for the diagnosis or treatment of dental disorders or dental pathology primarily affecting the gums, teeth, or alveolar ridge.
