About coding Eccentric personality
The ICD-10-CM code for Eccentric personality is F60.89 (Other specific personality disorders).
Within F60.8, choose F60.89 (Other specific personality disorders) only when documentation doesn't support a more specific option: Narcissistic personality disorder (F60.81).
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.
