Corros 70-79% of body surface w 70-79% third degree corros

This code signifies a severe chemical burn, or corrosion, affecting a substantial portion of the patient's body surface, specifically between 70% and 79%. A critical aspect is that the majority of this affected area, also 70% to 79%, involves full-thickness tissue destruction (third-degree corrosion). This indicates extensive and deep tissue damage.

Use this code for patients presenting with extensive chemical burns where the total body surface area (TBSA) involved is precisely documented as 70-79%. Furthermore, the medical record must clearly indicate that 70-79% of this affected TBSA is classified as third-degree corrosion. This code is appropriate for acute care settings following severe chemical exposure.

• Ensure documentation clearly specifies both the total body surface area affected by corrosion and the percentage of that area that is third-degree.
• Do not use this code if the percentages for total body surface area or third-degree corrosion fall outside the 70-79% range.
• Remember to also code for the external cause of the corrosion (e.g., chemical exposure) and any associated complications.
