About S83
S83 is the ICD-10-CM diagnosis code for dislocation and sprain of joints and ligaments of knee. It belongs to block S80-S89 (injuries to the knee and lower leg) 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.
To report this condition, pick the subcode that matches the documentation: S83.0 (patella), S83.1 (knee), S83.2 (injury), S83.3 (current), S83.4 (knee), S83.5 (knee), S83.6 (ligament), S83.8 (knee) and 1 more.
The conditions in its Excludes2 note aren't part of S83, but may be coded alongside it if the patient has both: derangement of patella (M22.0-M22.3), injury of patellar ligament (tendon) (S76.1-), internal derangement of knee (M23.-), old dislocation of knee (M24.36) and 3 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
