S93.11Dislocation of interphalangeal joint

S93.11 is the ICD-10-CM diagnosis code for dislocation of interphalangeal joint. 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 7 subcodes must be used instead.

Within S93.1 (subluxation and dislocation of toe), S93.11 is specifically for dislocation of interphalangeal joint. Related codes cover unspecified subluxation and dislocation of toe (S93.10), dislocation of metatarsophalangeal joint (S93.12), subluxation of interphalangeal joint (S93.13) and subluxation of metatarsophalangeal joint (S93.14).

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.
