This code signifies a healed or residual effect from a first-degree corrosion (chemical burn) affecting multiple areas of the shoulder and upper limb, excluding the wrist and hand. The original injury has resolved, but there are lasting consequences or complications.

Apply this code when documenting a patient presenting with a long-term issue directly attributable to a past first-degree chemical burn on various sites of their shoulder and upper arm. Examples include chronic pain, scarring, or limited range of motion resulting from the original corrosion.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., scar, chronic pain).
• Ensure documentation clearly links the current condition to a past first-degree chemical burn of the specified body regions.
• The "S" in the seventh character indicates a sequela, meaning the acute phase of the injury has passed.
