Corrosion of unspecified degree of unspecified ear, sequela

This code describes the long-term effects or complications resulting from a chemical burn of an unspecified degree to any part of the ear, excluding the eardrum. These sequelae can include scarring, tissue damage, or functional impairment that persists after the initial injury has healed.

Use this code when documenting a patient presenting with a chronic condition or residual effect directly attributable to a past chemical burn of the external or middle ear (excluding the tympanic membrane). This is appropriate for follow-up encounters addressing the lasting consequences of such an injury.

• Assign this code only for sequelae, not for the initial acute injury.
• Ensure documentation clearly links the current condition to a previous chemical burn of the ear.
• If the specific degree of corrosion or the exact part of the ear (other than the eardrum) is known, a more specific code should be used.
