Iowa Medicaid MNT coverage: codes and referrals

The short answerIowa Medicaid's rule pays for nutritional counseling by a licensed dietitian for members aged 20 and under, when the dietitian is employed by or under contract with a physician, hospital or screening center. The problem must be severe enough to need more than standard medical management. WIC-eligible members need a WIC referral. The HCBS health and disability waiver also lists nutritional counseling as a service. The rule names no CPT codes.
