Psychiatric-Mental Health Nurse Practitioner (PMHNP) Purple Book Practice Test

In DSM-5, there are no axes anymore. The axial system from DSM-IV is gone, so personality disorders aren’t coded on a separate axis. Instead, you assign a standard diagnosis code using ICD-10-CM for the personality disorder, just like you would for any other major psychiatric disorder. If there are additional comorbid conditions, you code them separately with their own ICD-10-CM codes and sequence them as clinically appropriate. So the idea is that coding aligns with the main diagnosis using the regular diagnostic codes, not an axis.
