Corrosion of second degree of right ear, sequela

This code signifies a second-degree chemical burn affecting any part of the right ear, excluding the eardrum, where the acute injury has healed and residual effects or complications are now being treated. Second-degree burns are characterized by blistering, pain, and partial-thickness skin damage.

Apply this code when documenting the long-term consequences or follow-up care for a past second-degree chemical burn to the right ear. This includes scenarios where the patient presents with scarring, altered sensation, or other chronic issues directly resulting from the initial corrosion. Do not use for the initial acute injury.

• Always use an external cause code (e.g., X10-X19 for contact with heat and hot substances) in conjunction with this code to fully describe the injury.
• Ensure the documentation clearly specifies "right ear" and "second degree" corrosion, excluding the eardrum.
• This "S" seventh character indicates a sequela, meaning it's used for complications or conditions arising as a direct result of the initial injury, after the acute phase has passed.
