W37 vs W50
W37 (Explosion and rupture of pressurized tire, pipe or hose) compared with W50 (Accidental hit, strike, kick, twist, bite or scratch by another person), 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. W37 carries an Excludes1 note covering W50: “contact or collision with animals or persons (W50-W64)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
