Insect bite (nonvenomous), left knee, subsequent encounter

This code indicates a non-venomous insect bite affecting the left knee, documented during a follow-up visit after initial treatment. It signifies that the patient is receiving continued care for the bite, which could include monitoring for complications, wound care, or assessment of healing.

Apply this code when a patient presents for a subsequent visit related to a non-venomous insect bite on their left knee. This includes scenarios where the patient is returning for re-evaluation of the bite, dressing changes, or management of persistent symptoms like itching or localized inflammation.

• Ensure documentation clearly specifies "left knee" and "nonvenomous" for accurate site and type of bite.
• The "D" seventh character is crucial for subsequent encounters; do not use for initial treatment or sequelae.
• Always review the medical record for any associated complications (e.g., infection, cellulitis) which would require additional codes.
