About X17.XXXD

X17.XXXD is the ICD-10-CM diagnosis code for contact with hot engines, machinery and tools, subsequent encounter. It belongs to category X17 (contact with hot engines, machinery and tools), block X10-X19 (contact with heat and hot substances) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

The 7th character "D" means subsequent encounter: use it for encounters after active treatment, while the patient is healing or recovering.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

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

Before ICD-10, this condition was coded in ICD-9-CM as E924.8 (accident caused by other hot substance or object).
