About coding manic episode
The ICD-10-CM code for manic episode is F30.9 (Manic episode, unspecified). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F30.9.
Within F30, choose F30.9 (unspecified) 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 other manic episodes (F30.8).
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.
