About coding thumb dislocation

The ICD-10-CM code for thumb dislocation is S63.10 (Unspecified subluxation and dislocation of thumb).

Within S63.1, choose S63.10 (Unspecified subluxation and dislocation of thumb) only when documentation doesn't support a more specific option: subluxation and dislocation of metacarpophalangeal joint of thumb (S63.11) and subluxation and dislocation of interphalangeal joint of thumb (S63.12).

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.
