S13.1Subluxation and dislocation of cervical vertebrae

S13.1 is the ICD-10-CM diagnosis code for subluxation and dislocation of 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 9 subcodes must be used instead.

Within S13 (dislocation and sprain of joints and ligaments at neck level), S13.1 is specifically for subluxation and dislocation of cervical vertebrae. Related codes cover traumatic rupture of cervical intervertebral disc (S13.0), dislocation of other and unspecified parts of neck (S13.2), sprain of ligaments of cervical spine (S13.4), sprain of thyroid region (S13.5), sprain of joints and ligaments of other parts of neck (S13.8) and sprain of joints and ligaments of unspecified parts of neck (S13.9).

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.

The conditions in its Excludes2 note aren't part of S13.1, but may be coded alongside it if the patient has both: fracture of cervical vertebrae (S12.0-S12.3-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
