Mississippi Senate passes ‘Jill’s Law,’ requiring insurance coverage for biomarker testing

JACKSON, Miss. (WLOX) - A bill that could affect thousands of Mississippians with diseases, including cancer and Alzheimer’s, is now awaiting the signature of Gov. Tate Reeves.

House Bill 565, known as “Jill’s Law,” passed unanimously in the Mississippi Senate on Wednesday after previously passing the House.

The bill is named in honor of Jill Eure, who died at 48 in 2025 after a battle with Multiple Myeloma. Jill is the late wife of state Rep. Casey Eure, who represents parts of Harrison County.

The legislation would require most health insurance plans to cover biomarker testing.

Biomarkers are measurable biological indicators that reveal the presence of a disease or signal an increased risk of developing one. Detecting these biomarkers can involve techniques such as imaging scans or analyzing samples of bodily fluids.

Supporters said the change will help remove obstacles that might keep people from getting an accurate diagnosis.

“Biomarker testing can help doctors detect Alzheimer’s earlier and make a more accurate diagnosis, allowing individuals and families to access treatment, clinical trials and care planning sooner,” said Blair Ewing, Government Relations Director for the Alzheimer’s Association Mississippi Chapter.

Under House Bill 565, plans that are entered into or renewed on or after July 1, 2026, would be covered.
