This appeal concerns the dismissal of a health care liability action for noncompliance with the Health Care Liability Act, specifically Tennessee Code Annotated § 29-26-121 (Supp. 2016). Before filing this action, the plaintiff gave timely written pre-suit notice of her health care liability claim, including the required medical authorizations, to all potential defendants. But when she filed her complaint, the plaintiff failed to provide copies of the medical authorizations as required by statute. Both defendants filed motions to dismiss based on the missing documents. The trial court determined that the plaintiff had substantially complied with the statute and that the defendants were not prejudiced by the omission. Even so, the court dismissed the complaint with prejudice after concluding that strict compliance with the statute was required when the defendant was a governmental entity. Upon review, we conclude that substantial compliance with the documentation requirement in Tennessee Code Annotated § 29-26-121(b) is sufficient even when the defendant is a governmental entity. Thus, we reverse the dismissal of the complaint.
