About W11.XXXA

W11.XXXA is the ICD-10-CM diagnosis code for fall on and from ladder, initial encounter. It belongs to category W11 (fall on and from ladder), 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 "A" means initial encounter: use it while the patient is receiving active treatment for the 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 E881.0 (accidental fall from ladder).
