Toxic effect of venom of Australian snake, self-harm, subs

This code signifies a harmful reaction resulting from the deliberate self-administration of venom from an Australian snake species not otherwise specified. The patient is experiencing the ongoing effects or complications from this intentional poisoning, rather than the initial acute event. This indicates a follow-up visit for management of the toxic effects.

Apply this code for subsequent encounters where a patient is being treated for the lingering or evolving toxic effects of intentionally self-inflicted Australian snake venom poisoning. This would include follow-up appointments for monitoring organ damage, managing neurological symptoms, or addressing coagulopathy after the initial emergency care. It is appropriate when the patient presents for ongoing care related to the self-harm attempt.

• Always sequence this code after the primary mental health diagnosis for the intentional self-harm.
• Ensure documentation clearly specifies "intentional self-harm" and "subsequent encounter" to support this code.
• Verify the snake species is Australian but not specifically identified as one of the more common types with dedicated codes.
