ICD Code T21 is a non-billable code. To code a diagnosis of this type, you must use one of the eight child codes of T21 that describes the diagnosis 'burn and corrosion of trunk' in more detail.

The ICD code T21 is used to code Burn

A burn is a type of injury to skin , or other tissues, caused by heat, electricity, chemicals, friction, or radiation. Burns that affect only the superficial skin layers are known as superficial or first-degree burns. When the injury extends into some of the underlying layers, it is described as a partial-thickness or second-degree burn. In a full-thickness or third-degree burn, the injury extends to all layers of the skin. A fourth-degree burn additionally involves injury to deeper tissues, such as muscle, tendons, or bone.

What is 7th Character Extension?

For codes less than 6 characters that require a 7th character a placeholder 'X' should be assigned for all characters less than 6. The 7th character must always be the 7th position of a code. E.g. The ICD-10-CM code T67.4 (Heat exhaustion due to salt depletion) requires an Episode of Care identifier. T67.4XXA Initial Encounter or T67.4XXD Subsequent Encounter. More Info
The appropriate 7th character is to be added to each code from category See Code T21
