What This Code Means

Chemical burn affecting 70-79% of the body surface with 20-29% deep tissue damage (third degree corrosion). This represents a life-threatening chemical injury with very extensive body surface and significant full-thickness involvement.

Coding Tips

•This severity level carries high mortality risk and requires immediate intensive care and specialized burn treatment
•Always append the appropriate seventh character for accurate episode of care tracking

Clinical Significance

This indicates life-threatening chemical burns covering 70-79% of the body with significant deep tissue destruction (20-29% third-degree), representing catastrophic injury requiring immediate specialized burn care. These patients require aggressive resuscitation, multiple surgical procedures, and face extremely high risk of mortality and severe complications.
