Amends TCA Title 56 and Title 71.

Tennessee HB0502 amends TCA Title 56 and Title 71 to require the bureau of TennCare to provide coverage for the diagnosis and treatment of Kleefstra syndrome, similar to existing coverage for autism spectrum disorder and Down syndrome, but with the amendment making this coverage permissive based on medical necessity. The bill affects enrollees of TennCare who are diagnosed with Kleefstra syndrome, allowing for potential benefits including genetic testing and various therapeutic interventions. Key changes in Amendment #1 shift the requirement for coverage from mandatory to permissive, contingent upon medical necessity, and similarly modify the scope of included benefits.
