S68.522Partial traumatic transphalangeal amputation of left thumb

S68.522 is the ICD-10-CM diagnosis code for partial traumatic transphalangeal amputation of left thumb. It belongs to category S68 (traumatic amputation of wrist, hand and fingers), 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 3 subcodes must be used instead.

Within S68.52 (partial traumatic transphalangeal amputation of thumb), S68.522 is specifically for partial traumatic transphalangeal amputation of left thumb. Related codes cover right thumb (S68.521) and unspecified thumb (S68.529).

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.
