The process of constructing codes in ICD-10-PCS is designed to be logical and consistent: individual letters and numbers, called “values,” are selected in sequence to occupy the seven spaces of the code, called “characters.” 

For 10 of the 16 ICD-10-PCS sections, the third character defines the root operation – the objective of the procedure. For the following ancillary sections, the third character defines the procedure by root type: Imaging, Nuclear Medicine, Radiation Therapy, Physical Rehabilitation and Diagnostic Audiology, Mental Health, and Substance Abuse Treatment.
