About W20.8XXS
W20.8XXS is the ICD-10-CM diagnosis code for other cause of strike by thrown, projected or falling object, sequela. It belongs to category W20 (struck by thrown, projected or falling object), 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.
Code first any associated: cataclysm (X34-X39) and lightning strike (T75.00).
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 E929.8 (late effects of other accidents).
