S63.1Subluxation and dislocation of thumb

S63.1 is the ICD-10-CM diagnosis code for subluxation and dislocation of thumb. 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 5 subcodes must be used instead.

Within S63 (dislocation and sprain of joints and ligaments at wrist and hand level), S63.1 is specifically for subluxation and dislocation of thumb. Related codes cover subluxation and dislocation of wrist and hand joints (S63.0), subluxation and dislocation of other finger(s) (S63.2), traumatic rupture of ligament of wrist (S63.3), traumatic rupture of ligament of finger at metacarpophalangeal and interphalangeal joint(s) (S63.4), other and unspecified sprain of wrist (S63.5), other and unspecified sprain of finger(s) (S63.6), sprain of other part of wrist and hand (S63.8) and sprain of unspecified part of wrist and hand (S63.9).

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.
