About the T32 Code Range

Corrosions here are described by how much of the body's surface they involve, rather than by the affected body region.

The first subdivision gives the total area involved, from less than 10% in T32.0 to 90% or more in T32.9. For totals of 10% or more, further subdivisions give the amount of body surface with third-degree corrosion. For example, T32.20 and T32.22 both involve 20–29% of body surface, but differ in the amount with third-degree corrosion.

Questions About This Page
