W44Foreign body entering into or through a natural orifice

W44 is the ICD-10-CM diagnosis code for foreign body entering into or through a natural orifice. It belongs to 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: W44.8 (orifice), W44.9 (orifice), W44.A (orifice), W44.B (orifice), W44.C (orifice), W44.D (orifice), W44.E (orifice), W44.F (orifice) and 2 more.

The conditions in its Excludes2 note aren't part of W44, but may be coded alongside it if the patient has both: contact with other sharp objects (W26), contact with sharp glass (W25) and foreign body or object entering through skin (W45).

It was added in FY2024, effective October 1, 2023.
