Corrosions of right ear drum, sequela

This code signifies the long-term effects or complications arising from a chemical burn to the right tympanic membrane. These sequelae can include persistent perforation, scarring, hearing loss, or chronic inflammation that developed as a direct result of the initial corrosive injury.

Use this code when documenting a patient presenting with a current condition that is a residual effect of a past corrosive injury to their right eardrum. This applies to follow-up encounters for chronic issues directly attributable to the original chemical burn, even if the acute injury has healed.

• Always ensure documentation clearly links the current condition to the previous corrosive injury.
• This code requires a seventh character 'S' for sequela, indicating a complication or residual effect.
• Do not use this code for acute corrosive injuries; those would be coded with an 'A' or 'D' seventh character.
