About S28.229
S28.229 is the ICD-10-CM diagnosis code for partial traumatic amputation of unspecified breast. It belongs to category S28 (crushing injury of thorax, and traumatic amputation of part of thorax), block S20-S29 (injuries to the thorax) 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 S28.22, choose S28.229 (unspecified breast) only when documentation doesn't support a more specific option: right breast (S28.221) and left breast (S28.222).
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.
