About coding personality disturbance
The ICD-10-CM code for personality disturbance is F60.9 (Personality disorder, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F60.9.
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.
