About S93.30

S93.30 is the ICD-10-CM diagnosis code for unspecified 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 6 subcodes must be used instead.

Within S93.3, choose S93.30 (Unspecified subluxation and dislocation of foot) only when documentation doesn't support a more specific option: subluxation and dislocation of tarsal joint (S93.31), subluxation and dislocation of tarsometatarsal joint (S93.32) and other subluxation and dislocation of foot (S93.33).

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.

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