Evidence - As introduced, states that in certain civil actions a licensed nurse practitioner or licensed physician assistant who is properly qualified as an expert witness may testify as to certain medical findings. - Amends TCA Title 24; Title 29, Chapter 26 and Title 50, Chapter 6.

SB 2048 allows licensed nurse practitioners and physician assistants to testify as expert witnesses in most civil cases regarding medical diagnoses, treatment, and medical causes, provided they are properly qualified under Tennessee evidence rules. This applies to general civil lawsuits but explicitly excludes medical malpractice cases (under Title 29, Chapter 26) and workers' compensation claims (under Title 50, Chapter 6). The bill does not change existing rules for workers' compensation panels or allow these professionals to provide testimony on impairment ratings or work-relatedness in such cases. It focuses solely on expanding qualified expert testimony in non-excluded civil matters.
