F31.1Bipolar disorder, current episode manic without psychotic features

F31.1 is the ICD-10-CM diagnosis code for bipolar disorder, current episode manic without psychotic features. It belongs to category F31 (bipolar disorder), block F30-F39 (mood [affective] disorders) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within F31, choose F31.1 (current episode manic without psychotic features) only when documentation doesn't support a more specific option: current episode hypomanic (F31.0), current episode manic severe with psychotic features (F31.2), current episode depressed, mild or moderate severity (F31.3), current episode depressed, severe, without psychotic features (F31.4), current episode depressed, severe, with psychotic features (F31.5), current episode mixed (F31.6), currently in remission (F31.7), other bipolar disorders (F31.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: F31.10 (unspecified), F31.11 (mild), F31.12 (moderate) and F31.13 (severe).

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