W. Va. Code § 55-7B-6
(b) At least 30 days prior to the filing of a medical professional liability action against a health care provider, the claimant shall serve by certified mail, return receipt requested, a notice of claim on each health care provider the claimant will join in litigation. For the purposes of this section, where the medical professional liability claim against a health care facility is premised upon the act or failure to act of agents, servants, employees, or officers of the health care facility, such agents, servants, employees, or officers shall be identified by area of professional practice or role in the health care at issue. The notice of claim shall include a statement of the theory or theories of liability upon which a cause of action may be based, and a list of all health care providers and health care facilities to whom notices of claim are being sent, together with a screening certificate of merit. The screening certificate of merit shall be executed under oath by a health care provider who:
(3) Devoted, at the time of medical injury, 60 percent of his or her professional time annually to the active clinical practice in his or her medical field or specialty, or to teaching in his or her medical field or specialty in an accredited university.
If the health care provider executing the screening certificate of merit meets the qualifications of subdivisions (1), (2), and (3) of this subsection, there shall be a presumption that the health care provider is qualified as an expert for the purpose of executing a screening certificate of merit. The screening certificate of merit shall state with particularity, and include: (A) The basis for the expert’s familiarity with the applicable standard of care at issue; (B) the expert’s qualifications; (C) the expert’s opinion as to how the applicable standard of care was breached; (D) the expert’s opinion as to how the breach of the applicable standard of care resulted in injury or death; and (E) a list of all medical records and other information reviewed by the expert executing the screening certificate of merit. A separate screening certificate of merit must be provided for each health care provider against whom a claim is asserted. The health care provider signing the screening certificate of merit shall have no financial interest in the underlying claim, but may participate as an expert witness in any judicial proceeding. Nothing in this subsection limits the application of Rule 15 of the Rules of Civil Procedure. No challenge to the notice of claim may be raised prior to receipt of the notice of claim and the executed screening certificate of merit.
