ICD-10-CM Alphabetic Index entries that lead to T32.30:

  • Corrosion (injury) (acid) (caustic) (chemical) (lime) (external) (internal) › extent (percentage of body surface) › 30-39 percent (0-9 percent third degree)
  • Corrosion (injury) (acid) (caustic) (chemical) (lime) (external) (internal) › unspecified site with extent of body surface involved specified › 30-39 percent (0-9 percent third degree)

U.S. Hospital Utilization

T32.30 appeared in too few sampled U.S. inpatient stays in 2023 to report a national estimate (AHRQ suppresses counts of 10 or fewer) — a rare inpatient diagnosis.

Official Coding Guidelines

Sequence blood vessel/nerve injury first (fragment)

injury is to the blood vessels or nerves, that injury should be sequenced first.

— ICD-10-CM Official Guidelines for Coding and Reporting, FY2026, Section I.C.19.b.2
Do not assign injury codes for iatrogenic injuries; code complication

3) Iatrogenic injuries Injury codes from Chapter 19 should not be assigned for injuries that occur during, or as a result of, a medical intervention. Assign the appropriate complication code(s).
