House Bill 70 amends Tennessee law to require that TennCare health benefit plans provide coverage and reimbursement for biomarker testing for preeclampsia, effective for plans renewed or issued on or after July 1, 2025. The bill defines key terms related to biomarker testing, including "biomarker," "biomarker test," and "health benefit plan." It stipulates that a pregnant woman may undergo biomarker testing for preeclampsia when ordered by her attending physician, and that such tests must be conducted according to nationally recognized clinical practice guidelines.

Additionally, the bill empowers the division of TennCare to create rules and take necessary administrative actions to implement this coverage requirement, ensuring compliance with the Uniform Administrative Procedures Act. The division may also submit new waiver applications or amendments to existing waivers to secure federal financial participation for Medicaid coverage related to this section. The act takes effect immediately for rulemaking purposes, while the coverage provisions will be effective starting July 1, 2025.
