S.D. Codified Laws § 58-29E-6
Except for utilization information, a third-party payor shall maintain information disclosed in response to a request under § 58-29E-4 as confidential and proprietary information, and may not use that information for any other purpose or disclose that information to any other person, except as provided in this chapter or in the pharmacy benefit management services contract between the parties.
A third-party payor that discloses information, in violation of this section, is subject to an action for injunctive relief and is liable for any damages that are the direct and proximate result of the disclosure.
Nothing in this section prohibits a third-party payor from disclosing confidential or proprietary information to the director, upon request. Information obtained by the director in accordance with this section is confidential and privileged, and is not open to public inspection or disclosure.
