Renal Care Group has received approval to expand kidney dialysis treatment in Tupelo.

The Mississippi State Department of Health announced Wednesday that it has issued a certificate of need, allowing the project to go forward.

The medical group will add a total of 30 end-stage kidney disease stations and 1,656 square feet to its facilities.

Mississippi requires a certificate of need as part of a process meant to avoid duplication of health care services and control costs.

The project is expected to cost $761,103.
