Insect bite (nonvenomous) of unspecified ear, sequela

This code indicates a long-term effect or complication resulting from a nonvenomous insect bite on an unspecified ear. It signifies that the initial acute injury has resolved, but residual symptoms or conditions persist.

Apply this code when documentation clearly states a sequela (e.g., scar, chronic dermatitis, nerve damage) directly attributable to a past nonvenomous insect bite of the ear. This code is used after the initial acute phase of the bite has passed.

• Always use a seventh character 'S' for sequela codes, indicating a late effect.
• Ensure documentation specifies the ear as "unspecified" if laterality is not documented.
• Code the specific nature of the sequela (e.g., L90.5 for scar, L30.9 for dermatitis) in addition to this sequela code.
