F31.64 vs F53
F31.64 (Bipolar disorder, current episode mixed, severe, with psychotic features) compared with F53 (Mental and behavioral disorders associated with the puerperium, not elsewhere classified), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. F53 carries an Excludes1 note covering F31.64: “mood disorders with psychotic features (F30.2, F31.2, F31.5, F31.64, F32.3, F33.3)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
