Insect bite (nonvenomous) of left ring finger, sequela

This code indicates a long-term or residual effect stemming from a nonvenomous insect bite on the left ring finger. These sequelae can include chronic pain, scarring, discoloration, or persistent itching that remains after the initial acute phase of the bite has resolved. It signifies that the patient is presenting for treatment of these lasting complications, not the initial bite itself.

Apply this code when documenting a patient encounter for ongoing issues directly attributable to a past nonvenomous insect bite on the left ring finger. This would be appropriate for follow-up visits where the primary focus is managing chronic symptoms like scar tissue, nerve damage, or persistent dermatological changes resulting from the original injury. Do not use for the initial treatment of an 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 previous nonvenomous insect bite on the left ring finger.
• The "S" seventh character indicates a sequela, meaning the patient is being seen for the late effects of the injury.
