About T25.2

T25.2 is the ICD-10-CM diagnosis code for burn of second degree of ankle and foot. It belongs to category T25 (burn and corrosion of 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 4 subcodes must be used instead.

Within T25 (burn and corrosion of ankle and foot), T25.2 is specifically for burn of second degree of ankle and foot. Related codes cover burn of unspecified degree of ankle and foot (T25.0), burn of first degree of ankle and foot (T25.1), burn of third degree of ankle and foot (T25.3), corrosion of unspecified degree of ankle and foot (T25.4), corrosion of first degree of ankle and foot (T25.5), corrosion of second degree of ankle and foot (T25.6) and corrosion of third degree of ankle and foot (T25.7).
