Corros 90%/more of body surface w 40-49% third degree corros

Corrosions involving 90% or more of body surface with 40-49% third degree corrosion

AIClinical Context

Clinical Description

This code signifies a severe chemical burn, or corrosion, affecting nearly the entire body surface (90% or more). Within this extensive area, a significant portion (40-49%) involves full-thickness tissue destruction, reaching the subcutaneous tissue.

When to Use

This code is appropriate for patients presenting with life-threatening chemical injuries covering most of their body, where nearly half of the affected area demonstrates complete destruction of the skin layers. This typically occurs in industrial accidents or severe chemical assaults.

Coding Tips

Ensure documentation clearly specifies both the total body surface area (TBSA) affected by corrosion and the percentage of third-degree involvement.
Do not use this code if the third-degree corrosion is less than 40% or greater than 49% of the total corroded area.
Code additional injuries, such as inhalation injury or organ damage, separately.
