Unspecified injury of left middle and inner ear, sequela

This code signifies a long-term complication or late effect resulting from an unspecified injury to the left middle and inner ear. This could encompass persistent hearing loss, tinnitus, vertigo, or other auditory or vestibular dysfunction that arose from a prior, unidentifiable traumatic event affecting these structures.

Use this code when documentation clearly indicates a sequela (late effect) of an injury to the left middle and inner ear, but the specific nature of the original injury is not documented or is unknown. This code is appropriate when the patient presents for treatment of the residual effects of the past injury, not the acute injury itself.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the original injury, if known.
• Ensure documentation specifies "sequela" or "late effect" and clearly links the current condition to a past injury.
• Do not use for acute injuries; instead, select an appropriate acute injury code from the S09 category.
