Corros 60-69% of body surface w 20-29% third degree corros

This code signifies a severe chemical burn (corrosion) affecting a substantial portion of the patient's body, specifically between 60% and 69% of the total body surface area. Within this extensive injury, a significant component, ranging from 20% to 29%, is classified as full-thickness (third-degree) damage.

Apply this code for patients presenting with extensive chemical injuries where the total body surface area affected falls within the 60-69% range, and a detailed assessment confirms that 20-29% of these burns are full-thickness. This is typically seen in industrial accidents or other severe exposures to corrosive substances.

• Ensure documentation clearly specifies both the total body surface area affected by corrosion and the percentage of third-degree involvement.
• Do not use this code if the percentage of third-degree corrosion falls outside the 20-29% range, even if the total body surface area is within 60-69%.
• Always sequence this code as a primary diagnosis when it represents the reason for the encounter, followed by codes for specific affected body sites if applicable.
