S58.929Partial traumatic amputation of unspecified forearm, level unspecified

S58.929 is the ICD-10-CM diagnosis code for partial traumatic amputation of unspecified 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 3 subcodes must be used instead.

Within S58.92, choose S58.929 (unspecified forearm, level unspecified) only when documentation doesn't support a more specific option: right forearm, level unspecified (S58.921) and left forearm, level unspecified (S58.922).

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.
