About coding Character neurosis
The ICD-10-CM code for Character neurosis is F60.9 (Personality disorder, unspecified).
Within F60, choose F60.9 (Personality disorder, unspecified) only when documentation doesn't support a more specific option: paranoid personality disorder (F60.0), Schizoid personality disorder (F60.1), antisocial personality disorder (F60.2), borderline personality disorder (F60.3), histrionic personality disorder (F60.4), obsessive-compulsive personality disorder (F60.5), Avoidant personality disorder (F60.6), dependent personality disorder (F60.7) and 1 more.
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.
