About W46.0
W46.0 is the ICD-10-CM diagnosis code for contact with hypodermic needle. It belongs to category W46 (contact with hypodermic needle), 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 W46 (contact with hypodermic needle), W46.0 is specifically for contact with hypodermic needle. Related codes cover contaminated hypodermic needle (W46.1).
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
