What This Code Means

Chemical burn affecting 60-69% of the body surface with 40-49% deep tissue damage (third degree corrosion). This represents a life-threatening chemical injury with extensive full-thickness involvement.

Coding Tips

•Document all associated complications and comorbidities that may affect treatment and prognosis
•Use the seventh character to track the patient's episode of care throughout treatment

Clinical Significance

This indicates life-threatening chemical burns covering 60-69% of the body with massive full-thickness destruction (40-49% third-degree), representing catastrophic injury requiring immediate burn center intervention. These patients face extremely high mortality risk and require extensive surgical reconstruction with prolonged intensive care and rehabilitation.

Documentation Requirements

✓Total body surface area involvement (60-69%)
✓Third-degree burn extent documentation (40-49%)
✓Chemical agent and exposure circumstances
✓Injury date and timeline of care
✓Current treatment phase and prognosis
✓Anatomical locations and patterns
✓Complications including organ dysfunction
✓Multiple surgical procedures and outcomes
