MCB 125 ICD 10.CM-09/15/2025

ICD-9 to ICD-10 transition

• ICD-9 was used for many years; it served as the historical disease/classification coding system.

• The lecture indicates that we have moved to ICD-10, the tenth revision of the classification system.

• This represents a shift from ICD-9 to ICD-10; ICD-10 is explicitly referenced as the tenth revision.
