Del. Code tit. 16 § 2225
In cases involving the existence or scope of private or public coverage for substance abuse treatment, attorneys retained or employed by the Department of Justice may represent persons seeking such coverage if the Department of Insurance is unable to provide such persons timely assistance with coverage disputes under the Department of Insurance's statutory authority vested by Title 18. The Department of Justice shall take appropriate organizational measures to ensure the integrity of its representation of state agencies when representing such persons. Attorneys shall certify when acting under this section that the treatments they are seeking pursuant to their representation are covered by the terms of the policies or plans at issue and are not experimental.
