About coding personality multiple
The ICD-10-CM code for personality multiple is F44.81 (Dissociative identity disorder).
Within F44.8 (other dissociative and conversion disorders), F44.81 is specifically for dissociative identity disorder. Related codes cover other dissociative and conversion disorders (F44.89).
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.
