About T32
T32 is the ICD-10-CM diagnosis code for Corrosions classified according to extent of body surface involved. It belongs to block T30-T32 (burns and corrosions of multiple and unspecified body regions) 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 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: T32.0 (surface), T32.1 (surface), T32.2 (surface), T32.3 (surface), T32.4 (surface), T32.5 (surface), T32.6 (surface), T32.7 (surface) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
