About coding Hypomania
The ICD-10-CM code for Hypomania is F30.8 (Other manic episodes).
Within F30, choose F30.8 (Other manic episodes) only when documentation doesn't support a more specific option: without psychotic symptoms (F30.1), severe with psychotic symptoms (F30.2), in partial remission (F30.3), in full remission (F30.4) and unspecified (F30.9).
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 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.
