F06.33Mood disorder due to known physiological condition with manic features

F06.33 is the ICD-10-CM diagnosis code for mood disorder due to known physiological condition with manic features. It belongs to category F06 (other mental disorders due to known physiological condition), block F01-F09 (mental disorders due to known physiological conditions) 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 F06.3 (mood disorder due to known physiological condition), F06.33 is specifically for mood disorder due to known physiological condition with manic features. Related codes cover unspecified (F06.30), with depressive features (F06.31), with major depressive-like episode (F06.32) and with mixed features (F06.34).

Code first: the underlying physiological condition.

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 884 (Organic Disturbances and Intellectual Disability, relative weight 1.6001), 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 293.83 (mood disorder in conditions classified elsewhere).
