J10 vs J11
J10 (Influenza due to other identified influenza virus) compared with J11 (Influenza due to unidentified influenza virus), 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. J10 carries an Excludes1 note covering J11: “influenza due to unidentifed influenza virus (J11.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
