About T30

T30 is the ICD-10-CM diagnosis code for burn and corrosion, body region unspecified. 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 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: T30.0 (degree) and T30.4 (degree).

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