The longtime legislator is expected to be named deputy director of administration for the state Division of Medicaid.
Moody, a farmer, has served in the legislator for 21 years and dedicated them to health care. He says he's not taking the position for the money.
Moody said he wants to provide health care to the disadvantaged and people in need in Mississippi. He can't start work at Medicaid until Gov. Haley Barbour signs legislation for the program. Those bills didn't reach the governor's desk Wednesday.
Barbour set a June 1 special election to replace Moody, whose district includes all of Winston County and parts of Kemper and Noxubee counties. Candidates' qualifying deadline is Monday.
