About W00.0XXS

W00.0XXS is the ICD-10-CM diagnosis code for fall on same level due to ice and snow, sequela. It belongs to category W00 (fall due to ice and snow), block W00-W19 (slipping, tripping, stumbling and falls) 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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as E929.3 (late effects of accidental fall).
