Intentional self-harm by sharp object (X78) ICD-10-CM
The X78 code range covers intentional self-harm by sharp object with 21 ICD-10-CM diagnosis codes. 15 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to each code from category X78
7th Character

About the X78 Code Range
Cutting or stabbing oneself with a sharp object is a form of intentional self-harm.
Within X78, subdivisions identify sharp glass, a knife, or a sword or dagger. Separate subdivisions cover other sharp objects and an unspecified sharp object. The final character distinguishes an initial encounter (A), a subsequent encounter (D), or a sequela (S, a later effect).
