Corrosion of unsp degree of trunk, unspecified site, sequela

This code indicates a long-term complication or late effect resulting from a corrosive burn of an unspecified degree affecting any part of the patient's trunk. The original corrosive injury has healed, but a residual condition or problem persists. The specific location on the trunk and the severity of the initial burn are not documented.

Use this code when a patient presents with a current condition (e.g., scar contracture, chronic pain, disfigurement) that is a direct consequence of a past corrosive burn to the trunk. This code is appropriate when the original burn's degree and precise location on the trunk are not specified in the medical record. It signifies that the current encounter is for the management of the sequela, not the acute injury.

• Always sequence this "S" code after the code describing the specific sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a past corrosive burn of the trunk.
• Avoid using this code for acute corrosive injuries; those require codes from the T20-T32 range without the "S" seventh character.
