About coding intermittent explosive disorder
The ICD-10-CM code for intermittent explosive disorder is F63.81 (Intermittent explosive disorder).
Within F63.8 (other impulse disorders), F63.81 is specifically for intermittent explosive disorder. Related codes cover other impulse disorders (F63.89).
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.
