Tort Liability and Reform - As introduced, increases the amount of medical, hospital, or doctor bills that are presumed in a civil action to have been necessary and reasonable if the bills are itemized in the complaint or civil warrant with an attached copy of the bills attached as an exhibit to the complaint or civil warrant, from a total of $4,000 to a total of $25,000. - Amends TCA Title 20, Chapter 1; Title 24, Chapter 5; Title 55, Chapter 12 and Title 56, Chapter 7.

HB 1123 increases the threshold for medical bills presumed necessary and reasonable in civil lawsuits from $4,000 to $25,000 when itemized bills are attached to the complaint as exhibits. This directly affects plaintiffs in medical malpractice or injury cases who can now have higher medical costs automatically accepted as valid without additional proof. The key mechanism requires plaintiffs to submit itemized bills with their complaint, shifting the burden of proof to defendants for amounts exceeding $25,000. The bill amends specific Tennessee codes and takes effect July 1, 2025.
