About coding above elbow corrosion
The ICD-10-CM code for above elbow corrosion is T22.439 (Corrosion of unspecified degree of unspecified upper arm). The official index lists 11 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T22.439.
Within T22.43, choose T22.439 (unspecified upper arm) only when documentation doesn't support a more specific option: right upper arm (T22.431) and left upper arm (T22.432).
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.
