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

This code describes the delayed or follow-up care for a patient who has experienced a toxic reaction to venom from a spider species other than a black widow or brown recluse. The injury was intentionally inflicted by another person.

Use this code for subsequent encounters related to the management of symptoms, complications, or sequelae arising from a spider venom exposure that was the result of an assault. This includes follow-up appointments for wound care, monitoring for systemic effects, or addressing persistent pain or tissue damage after initial treatment.

• Requires an external cause code (e.g., Y04.XXXD) to fully describe the assault.
• Confirm the spider type is not a black widow (T63.31-) or brown recluse (T63.32-) to ensure correct specificity.
• The "D" seventh character indicates subsequent care after the initial active treatment phase.
