About S04.031

S04.031 is the ICD-10-CM diagnosis code for injury of optic tract and pathways, right side. It belongs to category S04 (injury of cranial nerve), block S00-S09 (injuries to the head) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within S04.03 (injury of optic tract and pathways), S04.031 is specifically for injury of optic tract and pathways, right side. Related codes cover left side (S04.032) and unspecified side (S04.039).

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.

Code first: any associated intracranial injury (S06.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2018 (title revised).
