About Y27.3XXD

Y27.3XXD is the ICD-10-CM diagnosis code for contact with hot household appliance, undetermined intent, subsequent encounter. It belongs to category Y27 (contact with steam, hot vapors and hot objects, undetermined intent), block Y21-Y33 (event of undetermined intent) 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 E988.1 (injury by burns or fire, undetermined whether accidentally or purposely inflicted).
