Corrosion of second degree of left palm, sequela

This code signifies a past injury to the palm of the left hand caused by a corrosive substance, resulting in a second-degree burn. The "sequela" indicates that the patient is currently experiencing a residual effect or complication from this previous corrosive burn, rather than the acute injury itself.

This code is appropriate when a patient presents with a long-term complication or chronic condition directly attributable to a second-degree corrosive burn of their left palm that occurred in the past. Examples include scar contracture, chronic pain, or nerve damage stemming from the original injury. Do not use this code for the initial acute treatment of the burn.

• Always ensure documentation clearly links the current condition to the previous corrosive burn of the left palm.
• A "sequela" code is used for the late effects of an injury, not the initial treatment.
• Look for documentation specifying the degree of the burn and the laterality (left palm).
