W44.B9XS (Other plastic object entering into or through a natural orifice, sequela) 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. W44.B9XS 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).
