About W44.F0XS

W44.F0XS is the ICD-10-CM diagnosis code for objects of natural or organic material unspecified, entering into or through a natural orifice, sequela. It belongs to category W44 (foreign body entering into or through a natural orifice), block W20-W49 (exposure to inanimate mechanical forces) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

The 7th character "S" means sequela: use it for complications or conditions that arise as a direct result of the original condition.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

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