Pennsylvania Statutes Title 63 P.S. Professions and Occupations (State Licensed) § 213.1. Dietitian-nutritionist license required

(a) It shall be unlawful for any individual to hold himself or herself forth as a licensed dietitian-nutritionist unless he or she shall first have obtained a license pursuant to this act. Only individuals who have received licenses as licensed dietitian-nutritionists pursuant to this act may use the letters “L.D.N.” in connection with their names.

(b) Nothing in this section shall be construed to require or preclude third-party insurance reimbursement. Nothing herein shall preclude an insurer or other third-party payor from requiring that a licensed dietitian-nutritionist obtain a referral from a licensed physician, dentist or podiatrist or that a licensed dietitian-nutritionist file an evaluation and treatment plan with the insurer or third-party payor as a precondition of reimbursement.
