Struck by other hoof stock, subsequent encounter

This code indicates an injury sustained from being struck by a hoofed animal other than a horse, cow, or pig, during a subsequent encounter for the same injury. This could include animals like goats, sheep, deer, or llamas. The injury could range from contusions and abrasions to fractures or internal injuries.

Use this code when documenting follow-up care for a patient who was previously injured by being struck by a non-equine, non-bovine, non-porcine hoofed animal. This applies to situations such as wound checks, physical therapy for a fracture, or medication management for pain related to the initial incident.

• Ensure the encounter is explicitly documented as a "subsequent encounter" for the original injury.
• Always code the specific injury (e.g., fracture, contusion) first, followed by this external cause code.
• Verify the type of hoof stock involved to differentiate from W55.0 (horse), W55.2 (cow), or W55.4 (pig).
