Burn of third degree of unspecified knee, initial encounter

This code signifies a full-thickness burn affecting the knee joint, where all layers of skin and potentially underlying tissue are destroyed. The burn presents with charring, eschar formation, and often a lack of pain due to nerve damage. The specific knee (left or right) is not documented.

Apply this code for initial encounters when a patient presents with a third-degree burn to an unspecified knee. This includes emergency department visits, initial hospital admissions, or the first outpatient visit for this specific injury. It is appropriate when the laterality of the knee is not clearly documented in the medical record.

• Ensure documentation explicitly states "third-degree burn" and involves the "knee."
• Only use this code for the initial treatment encounter; subsequent encounters will require a different seventh character.
• Confirm the medical record does not specify left or right knee; if it does, a more specific code should be selected.
