Bill > HB565

This bill, known as "Jill's Law," mandates that all health benefit plans, including Medicaid and the State and School Employees Health Insurance Plan, must offer coverage for biomarker testing starting July 1, 2026. Biomarker testing involves analyzing a patient's biological samples to detect specific characteristics (biomarkers) that can indicate disease processes or predict response to treatment. This coverage is required when the use of such testing is supported by medical and scientific evidence, such as FDA-approved indications, drug labels, Medicare coverage decisions, or recommendations from recognized clinical practice guidelines or expert consensus statements. The law also aims to ensure that coverage for biomarker testing is provided without causing undue disruption to patient care and requires health plans to make their medical policies publicly available and update them promptly. If a claim for biomarker testing is denied, the health plan must provide a detailed written justification. Furthermore, the bill specifies timelines for approving or denying prior authorization requests for these tests and establishes a clear process for enrollees and providers to request exceptions to coverage policies. The Mississippi Department of Insurance will conduct audits to ensure compliance.
