Traumatic rupture of left ear drum, subsequent encounter

This code signifies a tear or perforation of the tympanic membrane in the left ear resulting from an injury, specifically when the patient is receiving follow-up care for the initial trauma. This includes situations where the patient is seen for routine follow-up, healing assessment, or complications arising from the initial rupture after the acute phase of treatment.

Apply this code for encounters where a patient is being treated for the sequelae or ongoing management of a previously diagnosed traumatic rupture of the left ear drum. Documentation should clearly indicate a traumatic etiology, laterality (left ear), and that the encounter is not for the initial active treatment of the injury.

• Ensure documentation specifies "left" ear and a traumatic cause.
• The "D" seventh character indicates subsequent encounter, used after the initial active treatment.
• Differentiate from non-traumatic ear drum perforations (e.g., otitis media) which use different code categories.
