Burn of third degree of left upper arm, initial encounter

This code signifies a full-thickness burn affecting the left upper arm, indicating damage through all layers of the skin, including subcutaneous tissue. Such burns typically present with a dry, leathery appearance, often without pain due to nerve destruction.

Apply this code for initial treatment of a patient presenting with a third-degree burn on their left upper arm. This includes emergency department visits, initial hospital admissions, or the first encounter for outpatient management of the acute injury.

• Ensure documentation specifies "third degree" and "left upper arm."
• Verify this is the initial encounter for the burn treatment. Subsequent encounters will require a different seventh character.
• Always code the external cause of the burn (e.g., X00-X19) in addition to the burn code.
