F06.7 vs I69.91
F06.7 (Mild neurocognitive disorder due to known physiological condition) compared with I69.91 (Cognitive deficits following unspecified cerebrovascular disease), 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. F06.7 carries an Excludes1 note covering I69.91: “cognitive deficits following (sequelae of) cerebral hemorrhage or infarction (I69.01-I69.11-, I69.21-I69.31-, I69.81- I69.91-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
