About X13.1XXA

X13.1XXA is the ICD-10-CM diagnosis code for other contact with steam and other hot vapors, initial encounter. It belongs to category X13 (contact with steam and other hot vapors), 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 "A" means initial encounter: use it while the patient is receiving active treatment for the condition.

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 E924.0 (accident caused by hot liquids and vapors, including steam).
