ICD and CDT Coding Examples

The tables in this resource link frequently reported CDT Codes with one or more possible ICD-10-CM diagnostic codes as examples. Please note that these tables, and especially their linkages, are not all-inclusive but serve only as a guide for commonly occurring conditions. Dentists, by virtue of their clinical education, experience and professional ethics, are the individuals responsible for diagnosis. As such, a dentist is also obligated to select the appropriate diagnosis code for patient records and claim submission. It is quite possible that other diagnoses and their associated codes may be appropriate for a given clinical scenario.
