About T25

T25 is the ICD-10-CM diagnosis code for burn and corrosion of ankle and foot. It belongs to 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: T25.0 (foot), T25.1 (foot), T25.2 (foot), T25.3 (foot), T25.4 (foot), T25.5 (foot), T25.6 (foot) and T25.7 (foot).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
