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

This code signifies a patient presenting for follow-up care or ongoing treatment after intentionally self-administering an unspecified snake venom. The initial acute phase of the poisoning has passed, and the patient is now managing residual effects or complications. This indicates a deliberate act of self-harm using snake venom, where the specific type of snake is not documented.

Use this code for subsequent encounters when a patient is receiving ongoing care for the toxic effects of an unspecified snake venom, and the poisoning was determined to be an act of intentional self-harm. This includes situations like follow-up appointments for organ damage, neurological sequelae, or psychological support related to the self-inflicted poisoning. It would not be used for the initial acute care encounter.

• Always sequence this code after the primary diagnosis for the specific toxic effect or complication being treated.
• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial treatment for the acute poisoning.
• If the specific snake venom is identified, a more specific code from the T63.0 category should be used.
