Non-billable headerICD-10-CM

T32 is a non-billable header ICD-10-CM code for corrosions classified according to extent of body surface involved. It cannot be billed on its own: choose one of the more specific child codes below.

Notes

Additional guidance from the ICD-10-CM tabular list.

  • 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.

Risk adjustment

T32 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead T32

10 child codes. Green means billable.
