About F60.3
F60.3 is the ICD-10-CM diagnosis code for borderline personality disorder. It belongs to category F60 (specific personality disorders), block F60-F69 (disorders of adult personality and behavior) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within F60 (specific personality disorders), F60.3 is specifically for borderline personality disorder. Related codes cover paranoid personality disorder (F60.0), Schizoid personality disorder (F60.1), antisocial personality disorder (F60.2), histrionic personality disorder (F60.4), obsessive-compulsive personality disorder (F60.5), Avoidant personality disorder (F60.6), dependent personality disorder (F60.7), other specific personality disorders (F60.8) and 1 more.
The conditions in its Excludes2 note aren't part of F60.3, but may be coded alongside it if the patient has both: antisocial personality disorder (F60.2).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 883 (Disorders of Personality and Impulse Control, relative weight 1.7697), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 301.3 (explosive personality disorder) and 301.83 (borderline personality disorder).
