Corrosions classified according to extent of body surface involved

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 10 more specific codes instead:

T32.0 Corrosions involving less than 10% of body surface
T32.1 Corrosions involving 10-19% of body surface (also a header)
T32.2 Corrosions involving 20-29% of body surface (also a header)
T32.3 Corrosions involving 30-39% of body surface (also a header)
T32.4 Corrosions involving 40-49% of body surface (also a header)
T32.5 Corrosions involving 50-59% of body surface (also a header)
T32.6 Corrosions involving 60-69% of body surface (also a header)
T32.7 Corrosions involving 70-79% of body surface (also a header)
T32.8 Corrosions involving 80-89% of body surface (also a header)
T32.9 Corrosions involving 90% or more of body surface (also a header)

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

Note

This category is to be used as the primary code only when the site of the corrosion is unspecified. It may be used as a supplementary code with categories T20-T25 when the site is specified.
