About S13
S13 is the ICD-10-CM diagnosis code for dislocation and sprain of joints and ligaments at neck level. It belongs to 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 7 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: S13.0 (disc), S13.1 (vertebrae), S13.2 (neck), S13.4 (spine), S13.5 (region), S13.8 (neck) and S13.9 (neck).
The conditions in its Excludes2 note aren't part of S13, but may be coded alongside it if the patient has both: strain of muscle or tendon at neck level (S16.1).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
