Other superficial bite of left thumb, subsequent encounter

This code indicates a superficial bite wound on the left thumb that is currently receiving follow-up care. The bite did not penetrate deeply into the skin, and the patient is past the initial phase of injury.

Apply this code when a patient presents for subsequent treatment of a minor bite to the left thumb, such as wound care, dressing changes, or monitoring for infection, after the initial encounter for the injury. This includes situations where the bite was from an animal or human.

• Ensure the documentation specifies "left thumb" and "superficial bite."
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine follow-up care during the healing phase.
• Always code the external cause of the bite (e.g., W53.01XA for dog bite) in addition to this diagnosis code.
