Nondiscrimination of coverage for certain surgical procedures involving bones or joints.

No health maintenance contract or policy which provides coverage for any diagnostic or surgical procedure involving bones or joints of the skeleton shall discriminate against coverage for any similar diagnostic or surgical procedure involving bones or joints of the jaw and facial region, if, under accepted medical standards, such procedure or surgery is medically necessary to treat conditions caused by congenital or developmental deformity, disease, or injury. This section shall not be construed to affect any other coverage under this part or to restrict the scope of coverage under any policy, plan, or contract. Nothing in this section shall be construed to discourage appropriate nonsurgical procedures or to prohibit the continued coverage of nonsurgical procedures in the treatment of a bone or joint of the jaw and facial region. Furthermore, nothing in this subsection requires coverage for care or treatment of the teeth or gums, for intraoral prosthetic devices, or for surgical procedures for cosmetic purposes.
