Crushed by nonvenomous snake, subsequent encounter

This code describes an injury where a patient has been crushed by a nonvenomous snake, and this encounter is for follow-up care after the initial treatment. This could involve ongoing management of fractures, soft tissue damage, or other complications resulting from the crushing injury.

This code is appropriate for subsequent visits related to the initial crushing injury caused by a nonvenomous snake. Examples include follow-up appointments for wound care, physical therapy for musculoskeletal injuries, or monitoring for delayed complications. It should be used after the initial encounter for the injury has been coded.

• Always assign an external cause code (W59.13XD) in conjunction with a code for the specific injury sustained (e.g., fracture, contusion).
• Ensure the 7th character 'D' is used only for subsequent encounters, not the initial treatment of the injury.
• Verify the snake was explicitly documented as nonvenomous; otherwise, a different external cause code may be necessary.
