About T34.41
T34.41 is the ICD-10-CM diagnosis code for frostbite with tissue necrosis of right arm. It belongs to category T34 (frostbite with tissue necrosis), block T33-T34 (frostbite) 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 T34.4 (frostbite with tissue necrosis of arm), T34.41 is specifically for frostbite with tissue necrosis of right arm. Related codes cover unspecified arm (T34.40) and left arm (T34.42).
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.
