WellCare announced Monday that Sonya Nelson is the new president of the health insurer’s Georgia operations.

Tampa-based WellCare is the biggest of the three HMO-like Care Management Organizations (CMOs) currently serving the Medicaid and PeachCare populations in Georgia, with about 571,000 members.

WellCare also has 40,000 Medicare Advantage plan members and 23,000 Medicare Prescription Drug Plan members in Georgia.  Nationally, the company serves about 3.9 million members.

Nelson comes from Amerigroup’s Louisiana operation, where she held executive positions.

“I am honored to have been chosen to lead WellCare’s operations in Georgia,” said Nelson in a statement. “My No. 1 goal is to help make the communities we serve healthier. This will encompass many coordinated strategies, including continuing to partner with the state and providers to offer quality health care access for our members; expanding our Medicare Advantage presence; and building on WellCare’s culture of service excellence.”

Nelson takes the WellCare helm right before open enrollment begins March 1 for more than 1.3 million Georgia Medicaid and PeachCare CMO members.

They will have a fourth company to choose from this year, CareSource, a nonprofit based in Ohio.
