`T32.80` Corrosions involving 80-89% of body surface with 0% to 9% third degree corrosion

Billable ICD-10-CM code, FY2026. Acts as a Complication or Comorbidity (CC) as a secondary diagnosis.

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.

MS-DRG index

Defines the logic of DRG(s) 935 in MDC 22.
