W33 vs X92
W33 (Accidental rifle, shotgun and larger firearm discharge and malfunction) compared with X92 (Assault by drowning and submersion), 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. W33 carries an Excludes1 note covering X92: “assault (X92-Y09)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
