This code indicates a second-degree chemical burn (corrosion) affecting the shoulder or any part of the upper limb, excluding the wrist and hand, where the specific location on the limb is not documented. It signifies a long-term complication or late effect resulting from the initial injury.

Use this code when documenting a current condition that is a direct consequence of a past second-degree chemical burn to the shoulder or upper arm, forearm, or elbow. This applies when the original burn site within that region was not precisely specified, and the sequela is being treated or evaluated.

• Always ensure the documentation clearly links the current condition to a previous second-degree chemical burn.
• Verify that the affected area is indeed the shoulder or upper limb, excluding the wrist and hand.
• The "S" in the seventh character indicates a sequela; ensure this is appropriate for the encounter.
