Corrosion of second degree of left ear, sequela

This code signifies a healed or residual injury from a second-degree chemical burn to the left ear, excluding the eardrum. It indicates that the initial burn has resolved, but there are lasting effects or complications from the original injury.

Use this code when documenting a patient presenting with a sequela (e.g., scarring, altered sensation, chronic pain, or functional impairment) resulting from a past second-degree chemical burn to the left ear. This applies to follow-up encounters for these long-term effects, not the initial acute injury.

• Assign this code for the long-term effects of the burn, not the acute phase.
• Always use the appropriate external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the injury.
• Ensure documentation clearly supports a "sequela" status, indicating a residual condition from a past burn.
