Diagnosis and Procedure Codes

Diagnosis codes, such as the ICD-10-CM, are officially called the International Classification of Diseases, 10th Revision, Clinical Modification. These codes describe an individual's disease or medical condition. Physicians determine the patient's diagnosis and document this in the medical record, while trained billers assign the diagnosis code numbers to the physician-documented diagnosis for use on hospital forms such as a superbill, the CMS 1500, and the UB-04.

CPT codes®, or the Current Procedural Terminology codes, are five-digit procedure codes that describe the service rendered by the healthcare professional. The MNT codes 97802, 97803, and 97804 are CPT® codes that RDNs use on claims to report nutrition services provided by the RDN. In addition to the MNT codes, there are other codes that may be used by RDNs.

Because codes change over time and across insurance programs, the Academy will keep members up-to-date with the current codes related to nutrition professionals.
