About the T30–T32 Code Range
ICD-10 codes T30 through T32 cover burns and corrosions affecting multiple or unspecified body regions, categorized by severity and extent. These codes apply when the exact location of the burn or corrosion is unknown or when injuries involve large portions of the body surface.
This range includes T30 for burns or corrosions with unspecified body regions or degrees, capturing various types such as thermal burns, chemical burns, and injuries like neonatal scalds or cigarette burns. It also comprehensively classifies burns (T31) and corrosions (T32) based on the percentage of body surface area involved—from less than 10% up to 90% or more—as well as the degree of damage, including third degree or full thickness burns. For example, codes like T31.10 and T32.10 indicate burns or corrosions involving 10-19% of body surface with 0-9% full thickness injury. Synonyms such as scald of skin, chemical burn, alkali burn, radiation burn, and terms related to burn depth (e.g., deep partial thickness burn) help coders accurately link diagnoses to the appropriate code. This detailed structure assists healthcare professionals in documenting the severity and extent of burn or corrosive injuries for diagnosis and treatment planning.
