Struck by nonvenomous snake, subsequent encounter

This code indicates that a patient is receiving follow-up care for an injury sustained from being struck by a nonvenomous snake. This could include treatment for contusions, abrasions, or other non-toxic effects resulting from the physical impact, rather than envenomation.

Apply this code for subsequent visits related to the initial incident, such as wound checks, physical therapy for musculoskeletal injuries, or management of secondary infections. It is appropriate when the patient is no longer in the acute phase of treatment for the initial injury.

• Always pair with an external cause code (e.g., Y92.830 for wilderness area) to provide context for the injury.
• Ensure the "D" seventh character is appropriate for subsequent care; "A" is for initial encounters and "S" for sequela.
• Do not use this code if the snake was venomous; refer to codes in the T63.0- category for toxic effects.
