About W10.2XXD

W10.2XXD is the ICD-10-CM diagnosis code for fall (on)(from) incline, subsequent encounter. It belongs to category W10 (fall on and from stairs and steps), 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 "D" means subsequent encounter: use it for encounters after active treatment, while the patient is healing or recovering.

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 E880.9 (accidental fall on or from other stairs or steps).
