In simple words: This code describes the extent of chemical burns on the body when the specific location of the burn isn't known.It's used when the burn covers multiple areas or an unspecified area.

Corrosions classified according to extent of body surface involved. 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.

Example 1: A patient presents to the emergency room after spilling a strong cleaning agent on their torso and arms. The extent of the burns is still being evaluated, so T32 is used until the affected percentage can be determined., A child is brought in after ingesting a corrosive substance. The internal burns affect multiple areas of the digestive system.Because the extent and specific locations are not immediately clear, T32 is initially used., A worker suffers chemical burns from an industrial accident. The burns affect multiple body parts, and the total percentage is still being assessed during initial treatment, making T32 appropriate.

Documentation should include the percentage of body surface area affected, the depth of the burns, the causative agent (if known), and any other relevant clinical findings.
