About S58.9
S58.9 is the ICD-10-CM diagnosis code for traumatic amputation of forearm, level unspecified. It belongs to category S58 (traumatic amputation of elbow and forearm), block S50-S59 (injuries to the elbow and forearm) 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 2 subcodes must be used instead.
Within S58, choose S58.9 (of forearm, level unspecified) only when documentation doesn't support a more specific option: at elbow level (S58.0) and at level between elbow and wrist (S58.1).
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.
Don't report S58.9 together with the conditions in its Excludes1 note: traumatic amputation of wrist (S68.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
