Insect bite (nonvenomous) of left ear, sequela

This code indicates a long-term or residual effect stemming from a nonvenomous insect bite that occurred on the patient's left ear. This could include scarring, chronic dermatitis, or persistent disfigurement resulting from the initial injury. The original acute injury is no longer present, but its lasting impact is being addressed.

Apply this code when documenting a patient encounter where the primary reason for the visit is to manage or treat a condition that is a direct consequence of a past nonvenomous insect bite to the left ear. Examples include surgical revision of a scar from an old bite, or ongoing treatment for chronic inflammation at the bite site. It should not be used for the initial acute bite.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a past nonvenomous insect bite on the left ear.
• Do not use this code if the insect bite is still acute or if the insect was venomous.
