S93.3Subluxation and dislocation of foot

S93.3 is the ICD-10-CM diagnosis code for subluxation and dislocation of foot. It belongs to category S93 (dislocation and sprain of joints and ligaments at ankle, foot and toe level), block S90-S99 (injuries to the ankle and foot) 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 4 subcodes must be used instead.

Within S93 (dislocation and sprain of joints and ligaments at ankle, foot and toe level), S93.3 is specifically for subluxation and dislocation of foot. Related codes cover subluxation and dislocation of ankle joint (S93.0), subluxation and dislocation of toe (S93.1), sprain of ankle (S93.4), sprain of toe (S93.5) and sprain of foot (S93.6).

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 S93.3, but may be coded alongside it if the patient has both: dislocation of toe (S93.1-).

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