About coding recurrent mania
The ICD-10-CM code for recurrent mania is F31.89 (Other bipolar disorder).
Within F31.8, choose F31.89 (Other bipolar disorder) only when documentation doesn't support a more specific option: bipolar II disorder (F31.81).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 885 (Psychoses, relative weight 1.3901), 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.
