About coding suicide
The ICD-10-CM code for suicide is T14.91 (Suicide attempt). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T14.91.
Within T14.9 (unspecified injury), T14.91 is specifically for suicide attempt. Related codes cover injury, unspecified (T14.90).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2018 (expanded into subcodes).
