About coding Violence
The ICD-10-CM code for Violence is R45.6 (Violent behavior).
Within R45 (symptoms and signs involving emotional state), R45.6 is specifically for Violent behavior. Related codes cover Nervousness (R45.0), Restlessness and agitation (R45.1), unhappiness (R45.2), Demoralization and apathy (R45.3), irritability and anger (R45.4), Hostility (R45.5), state of emotional shock and stress, unspecified (R45.7) and other symptoms and signs involving emotional state (R45.8).
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.
