About T24.0
T24.0 is the ICD-10-CM diagnosis code for burn of unspecified degree of lower limb, except ankle and foot. It belongs to category T24 (burn and corrosion of lower limb, except ankle and foot), block T20-T25 (burns and corrosions of external body surface, specified by site) 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 5 subcodes must be used instead.
Within T24, choose T24.0 (Burn of unspecified degree of lower limb, except ankle and foot) only when documentation doesn't support a more specific option: burn of first degree of lower limb, except ankle and foot (T24.1), burn of second degree of lower limb, except ankle and foot (T24.2), burn of third degree of lower limb, except ankle and foot (T24.3), corrosion of unspecified degree of lower limb, except ankle and foot (T24.4), corrosion of first degree of lower limb, except ankle and foot (T24.5), corrosion of second degree of lower limb, except ankle and foot (T24.6) and corrosion of third degree of lower limb, except ankle and foot (T24.7).
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.
Use an additional code for: external cause code to identify the source, place and intent of the burn (X00-X19, X75-X77, X96-X98, Y92).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
