T32 — Corrosions classified according to extent of body surface involved
Not billable
Is T32 billable?
No — T32 is a non-billable header code. T32 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 55 billable codes beneath T32.

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.
Use additional code — inherited from Chapter 19
Report an additional code alongside T32 to fully describe the condition. T32 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T32, but a patient may have both at the same time. When documentation supports it, T32 and the excluded code may both be reported.

How long has T32 existed?
T32 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
