About coding impulse control disorder
The ICD-10-CM code for impulse control disorder is F63.9 (Impulse disorder, unspecified).
Within F63, choose F63.9 (Impulse disorder, unspecified) only when documentation doesn't support a more specific option: pathological gambling (F63.0), Pyromania (F63.1), Kleptomania (F63.2), Trichotillomania (F63.3) and other impulse disorders (F63.8).
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 886 (Behavioral and Developmental Disorders, relative weight 1.8678), 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.
