About the T31 Code Range

Burns in this category are grouped by how much of the body's surface is burned, not by where the burns occur.

The subdivisions start with the total area burned, from less than 10% in T31.0 to 90% or more in T31.9. Beginning with the 10–19% group, codes divide further by how much of the body's surface has third-degree burns. For example, T31.21 describes burns involving 20–29% of the body surface, with 10–19% third-degree burns.
