Corrosion of second degree of left upper arm, sequela

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

Use this code when documenting the long-term effects or complications arising from a second-degree corrosive burn to the left upper arm. This would apply to follow-up encounters where the initial burn has healed, but the patient presents with issues such as scarring, contracture, or chronic pain directly attributable to the original injury.

• Always use an external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the corrosion.
• Ensure documentation clearly specifies the sequela or residual condition being treated, not the acute burn.
• Verify the burn was indeed second-degree and located on the left upper arm.
