This code signifies a first-degree corrosion injury affecting multiple areas of the right shoulder and upper arm, excluding the wrist and hand. "Corrosion" indicates a chemical burn, and "first-degree" means only the outermost layer of skin is damaged, typically presenting with redness and mild pain. The "sequela" designation indicates this code is used for complications or conditions arising directly from the initial corrosion injury, after the acute phase has passed.

Use this code when documenting a current condition or complication that is a direct result of a past first-degree chemical burn to the specified areas of the right upper limb. This could include persistent skin discoloration, scarring, or sensitivity that developed after the initial burn healed. It is appropriate for follow-up encounters addressing these long-term effects.

• Always sequence this sequela code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a previous first-degree chemical burn of the right shoulder/upper limb.
• Do not use this code for acute chemical burns; instead, use the appropriate acute corrosion code.
