F31
Header — not billableBipolar disorder
The ICD-10 code for bipolar disorder is F31.
F31 is a non-billable header code. It groups related conditions but cannot be used on its own for reimbursement — select one of the 10 more specific codes below.
Clinical notes
Excludes1 (not coded here)
An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).
Excludes2 (not included here)
An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.
- cyclothymia (F34.0)
