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

This code signifies a patient presenting with adverse systemic effects resulting from exposure to venom from a spider species other than a black widow or brown recluse. The exposure is explicitly documented as an act of intentional self-harm. The "A" suffix indicates that this is the initial encounter for this specific injury.

Apply this code when a patient is admitted or seen for the first time due to a toxic reaction from a spider bite, where the patient deliberately inflicted the bite upon themselves. This would include situations where the patient intentionally provoked or handled a venomous spider to cause harm.

• Ensure documentation clearly states the spider bite was an act of intentional self-harm, not accidental or assault.
• Confirm the spider species is not a black widow (T63.31-) or brown recluse (T63.32-); otherwise, a more specific code is required.
• Always assign an external cause code (e.g., X20.XXXA for contact with venomous spiders) and a code for the intent (e.g., X83.XXXA for intentional self-harm by other specified means).
