(a)

(1) The trial court, in its discretion, may allow a physician who meets the other requirements of this part but does not meet the time and revenue requirements under § 29-34-702(24)(B) to be considered a qualified physician and submit a report required by this part if the trial court makes an evidentiary finding, after all parties have had a reasonable opportunity to present evidence, that it would be manifestly unjust not to allow the physician at issue to submit the report.

(2) For subsection (a) to apply, the trial court also must make specific and detailed findings, setting forth the bases of such findings, that the physician's opinions appear to be reliable medical opinions in that they are supported by documented, reliable medical evidence obtained through testing or examinations that comply with and do not violate any applicable law, regulation, licensing requirement, or medical code of practice and that the opinions are not the product of bias or the result of financial influence due to the physician's role as a paid expert.

(3) The cost of retaining another physician who is qualified pursuant to § 29-34-702(24)(B) for the purpose of submitting a report required by this part shall not be considered in determining manifest injustice, but the availability or unavailability of other physicians who meet such time and revenue requirements shall be considered as a relevant factor.

(b) A physician who submits a report under this part may be an expert witness retained by counsel for the exposed person or claimant; provided, that the physician otherwise meets the requirements of this part, § 24-7-115, and the Tennessee Rules of Evidence governing the qualifications of expert witnesses.
