W26.0Contact with knife

W26.0 is the ICD-10-CM diagnosis code for contact with knife. It belongs to category W26 (contact with other sharp objects), block W20-W49 (exposure to inanimate mechanical forces) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within W26 (contact with other sharp objects), W26.0 is specifically for contact with knife. Related codes cover sword or dagger (W26.1), edge of stiff paper (W26.2), other sharp object(s), not elsewhere classified (W26.8) and unspecified sharp object(s) (W26.9).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Don't report W26.0 together with the conditions in its Excludes1 note: contact with electric knife (W29.1).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
