Toxic effect of venom of other spider, assault, init encntr

This code signifies a harmful reaction resulting from the venom of a spider species other than a black widow or brown recluse, when the exposure was intentionally inflicted by another person. The patient is in the acute phase of treatment for this toxic effect.

Apply this code when documenting a patient presenting with symptoms of envenomation from an unspecified or less common spider, and the medical record clearly indicates the bite was the result of an assault. This is appropriate for the initial visit where the injury is evaluated and treatment is initiated.

• Always confirm the intent (assault) and the specific spider type (other than black widow/brown recluse) from the medical documentation.
• Ensure the "A" seventh character is used only for the initial encounter for this condition.
• Consider additional codes for specific symptoms or complications arising from the envenomation.
