(a) This section applies to a person participating in peer review, a medical peer review committee, or a health care entity named as a defendant in a civil action filed as a result of participation in peer review.
(b) A defendant subject to this section may use otherwise confidential information obtained for legitimate internal business and professional purposes, including use in the defendant's own defense. Use of confidential information under this subsection does not constitute a waiver of the confidential and privileged nature of medical peer review committee proceedings.
(c) A defendant subject to this section may file a counterclaim in a pending action or may prove a cause of action in a subsequent action to recover defense costs, including court costs, attorney's fees, and damages incurred as a result of the civil action, if the plaintiff's original action is determined to be frivolous or brought in bad faith.
