S.C. Code § 44-115-50
A physician may rely on the representations of a health and life insurance carrier or administrator of health and life insurance claims that the authorization of the patient or of a person upon whose status the patient's claim depends for release of the medical record is on file with the carrier as an authorization to release medical information under this chapter. A physician who in good faith releases medical information for claims processing relying on the representations of the claims administrator that an authorization for release of the information is on file is immune from any civil or criminal liability alleged to be caused by the physician's compliance with the request to release the information. The physician is not subject to disciplinary action for an alleged violation of law or regulation due to the compliance with the request to release information.
