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 X77

About the X77 Code Range
The ICD-10 code X77 covers intentional self-harm caused by steam, hot vapors, hot fluids, hot household appliances, or other hot objects. This category includes specific codes for different types of hot sources such as hot tap water (X77.1) and other hot fluids (X77.2).
These codes allow healthcare providers and coders to document cases where individuals intentionally harm themselves through burns or scalding injuries using hot substances or objects. For example, using X77.8 helps identify self-injury by other hot objects, which includes burns from cigarette use—commonly known as "self injury by cigarette burn." The code X77.9 is used for unspecified hot objects, also referred to as "self-scalding." Each code also distinguishes the stage of treatment with seventh-character extensions indicating initial encounters, subsequent encounters, and sequela—complications or conditions resulting from the injury. This system aids in accurately coding the cause and treatment phase of intentional burn injuries involving hot materials.
