Other superficial bite of right thumb, subsequent encounter

This code signifies a superficial bite wound on the right thumb that is being treated in a follow-up visit. The injury does not involve deep tissue, such as muscle, tendon, or bone, and is typically limited to the skin and subcutaneous tissue.

Apply this code for subsequent encounters when a patient presents for ongoing care of a superficial bite to their right thumb, such as wound checks, dressing changes, or antibiotic follow-up. This includes situations where the initial injury has already been documented with an initial encounter code.

• Ensure the documentation clearly specifies the right thumb and that the bite is superficial.
• Confirm this is a subsequent encounter for the same injury, not an initial presentation or a new injury.
• Always pair with an external cause code (e.g., W53.-, W54.-, W55.-) to indicate the source of the bite.
