About W45.3XXS

W45.3XXS is the ICD-10-CM diagnosis code for fishing hook entering through skin, sequela. It belongs to category W45 (foreign body or object entering through skin), 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 FY2026, effective October 1, 2025.
