Toxic effect of unsp spider venom, self-harm, init

This code describes the adverse systemic effects resulting from exposure to an unspecified spider's venom, where the exposure was deliberately self-inflicted. The patient is in the acute phase of treatment for these toxic effects.

Apply this code when a patient presents with symptoms of spider envenomation, and documentation clearly indicates the exposure was a conscious act of self-harm, such as an attempted suicide. This code is appropriate for the initial visit or encounter where the patient is actively being treated for the immediate effects of the poisoning.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires an additional code for the specific spider if known (e.g., black widow, brown recluse).
• Utilize an external cause code (e.g., X69.-) to further specify the intent and circumstances of the self-harm.
