About F63.0
F63.0 is the ICD-10-CM diagnosis code for pathological gambling. It belongs to category F63 (impulse 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 F63 (impulse disorders), F63.0 is specifically for pathological gambling. Related codes cover Pyromania (F63.1), Kleptomania (F63.2), Trichotillomania (F63.3), other impulse disorders (F63.8) and impulse disorder, unspecified (F63.9).
Don't report F63.0 together with the conditions in its Excludes1 note: gambling and betting NOS (Z72.6).
The conditions in its Excludes2 note aren't part of F63.0, but may be coded alongside it if the patient has both: excessive gambling by manic patients (F30, F31) and gambling in 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 312.31 (pathological gambling).
