Health Care - As introduced, authorizes a patient with a severe chronic disease or terminal illness to access, and a physician to recommend, investigational stem cell treatment; requires the commissioner of health to promulgate rules to, among other things, list the medical conditions that constitute a qualifying severe chronic disease or terminal illness. - Amends TCA Title 53; Title 63 and Title 68.

HB 413 allows patients with severe chronic diseases or terminal illnesses to access investigational stem cell treatments, as recommended by their physician after considering all FDA-approved options. The bill requires the Tennessee Commissioner of Health to create rules listing qualifying medical conditions and mandates written informed consent from patients (or guardians for minors). It also prohibits government interference with patient access and protects physicians from license penalties for following the law's guidelines. The bill directly affects patients with qualifying conditions and their treating physicians, establishing clear pathways for accessing non-FDA-approved stem cell therapies under specific safeguards.
