Corrosion of second degree of unspecified upper arm, sequela

This code signifies a long-term complication or late effect resulting from a second-degree corrosive injury to an unspecified area of the upper arm. This could include scarring, contractures, chronic pain, or functional limitations that persist after the initial corrosive burn has healed. The "unspecified" nature indicates that the exact location on the upper arm was not documented.

Use this code when documenting a patient presenting for follow-up care or treatment of a residual condition directly attributable to a second-degree corrosive burn of the upper arm that occurred in the past. This applies when the acute phase of the injury has passed, and the patient is now dealing with the lasting consequences.

• Always ensure documentation clearly links the current condition to the past corrosive injury.
• Verify that the burn was indeed second-degree and involved the upper arm.
• The "S" in the seventh character indicates sequela; do not use for acute or initial treatment.
