T33.8Superficial frostbite of ankle, foot, and toe(s)

T33.8 is the ICD-10-CM diagnosis code for superficial frostbite of ankle, foot, and toe(s). It belongs to category T33 (superficial frostbite), 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 T33 (superficial frostbite), T33.8 is specifically for superficial frostbite of ankle, foot, and toe(s). Related codes cover of head (T33.0), of neck (T33.1), of thorax (T33.2), of abdominal wall, lower back and pelvis (T33.3), of arm (T33.4), of wrist, hand, and fingers (T33.5), of hip and thigh (T33.6), of knee and lower leg (T33.7) and 1 more.

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.
