About S03

S03 is the ICD-10-CM diagnosis code for dislocation and sprain of joints and ligaments of head. It belongs to 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S03.0 (jaw), S03.1 (nose), S03.2 (tooth), S03.4 (jaw), S03.8 (head) and S03.9 (head).

The conditions in its Excludes2 note aren't part of S03, but may be coded alongside it if the patient has both: Strain of muscle or tendon of head (S09.1).

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