Contact with steam, hot vapors and hot objects, undetermined intent (Y27)

The ICD-10 code Y27 category is used to document injuries resulting from contact with steam, hot vapors, or hot objects where the intent behind the injury is not determined. These codes cover situations involving various sources of heat exposure, including hot tap water, hot fluids, household appliances, and other hot items.

This section is crucial for accurately coding cases where it is unclear if the injury was accidental or intentional, providing detailed subdivisions such as initial encounter (Y27.0XXA), subsequent encounters (Y27.0XXD), and sequela (Y27.0XXS). For example, contact with steam or hot vapors falls under Y27.0, while burns from hot tap water are captured by Y27.1. Medical coders use these codes to indicate both the source of the heat and the timing of treatment, ensuring comprehensive injury documentation. Understanding the use of ICD-10 code Y27 helps distinguish among various types of undetermined hot object injuries, which is important for clinical records and statistical tracking of burns and scalds where intent is unclear.

Instructional Notations

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category Y27

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela
