About Z72.811
Z72.811 is the ICD-10-CM diagnosis code for adult antisocial behavior. It belongs to category Z72 (problems related to lifestyle), block Z69-Z76 (persons encountering health services in other circumstances) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Z72.81 (antisocial behavior), Z72.811 is specifically for adult antisocial behavior. Related codes cover child and adolescent antisocial behavior (Z72.810).
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 880 (Acute Adjustment Reaction and Psychosocial Dysfunction, relative weight 0.9306), 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.
The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
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 V71.01 (observation for adult antisocial behavior).
