Diagnosis codes describe an individual's medical condition and are required on claims submitted by healthcare professionals to third party payers. ICD-9 — or the International Classification of Diseases, Ninth Revision — is the current official code set used for tracking disease/condition incidence in all health care settings in the United States.
Healthcare professionals can learn more about ICD-9 codes at the National Center for Health Statistics' website or through various coding books. Others prefer to hire billing staff or services familiar with ICD-9 codes and billing procedures.
Academy members have access to code lists, toolkits and resources specific to coding for Medical Nutrition Therapy, nutrition education and training services.
