About coding manic disorder
The ICD-10-CM code for manic disorder is F30.9 (Manic episode, unspecified). The official index lists 1 more specific code, 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.
