About X78.0XXS

X78.0XXS is the ICD-10-CM diagnosis code for intentional self-harm by sharp glass, sequela. It belongs to category X78 (intentional self-harm by sharp object), block X71-X83 (intentional self-harm) 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 E959 (late effects of self-inflicted injury).
