About F30.4

F30.4 is the ICD-10-CM diagnosis code for manic episode in full remission. It belongs to category F30 (manic episode), block F30-F39 (mood [affective] disorders) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within F30 (manic episode), F30.4 is specifically for manic episode in full remission. Related codes cover without psychotic symptoms (F30.1), severe with psychotic symptoms (F30.2), in partial remission (F30.3), other manic episodes (F30.8) 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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 296.06 (bipolar I disorder, single manic episode, in full remission).
