About S13.151

S13.151 is the ICD-10-CM diagnosis code for dislocation of C4/C5 cervical vertebrae. It belongs to category S13 (dislocation and sprain of joints and ligaments at neck level), block S10-S19 (injuries to the neck) 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 S13.15 (subluxation and dislocation of C4/C5 cervical vertebrae), S13.151 is specifically for dislocation of C4/C5 cervical vertebrae. Related codes cover subluxation of C4/C5 cervical vertebrae (S13.150).

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 hasn't changed since.
