S.C. Code Ann. § 38-33-290: Participation by physician, podiatrist, optometrist, or oral surgeon as provided in HMO.

No health maintenance organization may prohibit any licensed physician, podiatrist, optometrist, or oral surgeon from participating as a provider in the organization on the basis of his profession. Nothing in this section may be construed to interfere in any way with the medical decision of the primary health care provider to use or not use any health professional on a case-by-case basis.
