W20 vs X71
W20 (Struck by thrown, projected or falling object) compared with X71 (Intentional self-harm 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. W20 carries an Excludes1 note covering X71: “intentional self-harm (X71-X83)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
