About S63.63
S63.63 is the ICD-10-CM diagnosis code for sprain of interphalangeal joint of other and unspecified finger(s). 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 S63.6, choose S63.63 (Sprain of interphalangeal joint of other and unspecified finger(s)) only when documentation doesn't support a more specific option: unspecified sprain of thumb (S63.60), unspecified sprain of other and unspecified finger(s) (S63.61), sprain of interphalangeal joint of thumb (S63.62), sprain of metacarpophalangeal joint of thumb (S63.64), sprain of metacarpophalangeal joint of other and unspecified finger(s) (S63.65), other sprain of thumb (S63.68) and other sprain of other and unspecified finger(s) (S63.69).
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.
