About X11.1

X11.1 is the ICD-10-CM diagnosis code for contact with running hot water. It belongs to category X11 (contact with hot tap-water), block X10-X19 (contact with heat and hot substances) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within X11 (contact with hot tap-water), X11.1 is specifically for contact with running hot water. Related codes cover hot water in bath or tub (X11.0) and other hot tap-water (X11.8).

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.

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