About W03.XXXA
W03.XXXA is the ICD-10-CM diagnosis code for other fall on same level due to collision with another person, initial encounter. It belongs to category W03 (other fall on same level due to collision with another person), 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 E886.0 (fall on same level from collision, pushing, or shoving, by or with other person in sports).
