About S63.22

S63.22 is the ICD-10-CM diagnosis code for subluxation of unspecified interphalangeal joint of finger. It belongs to category S63 (dislocation and sprain of joints and ligaments at wrist and hand level), block S60-S69 (injuries to the wrist, hand and fingers) 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 10 subcodes must be used instead.

Within S63.2, choose S63.22 (Subluxation of unspecified interphalangeal joint of finger) only when documentation doesn't support a more specific option: unspecified subluxation of other finger (S63.20), subluxation of metacarpophalangeal joint of finger (S63.21), subluxation of proximal interphalangeal joint of finger (S63.23), subluxation of distal interphalangeal joint of finger (S63.24), unspecified dislocation of other finger (S63.25), dislocation of metacarpophalangeal joint of finger (S63.26), dislocation of unspecified interphalangeal joint of finger (S63.27), dislocation of proximal interphalangeal joint of finger (S63.28) and 1 more.

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.
