Toxic effect of venom of other spider, assault, sequela

This code signifies a long-term or residual health problem resulting from a deliberate act of poisoning by the venom of a spider species not otherwise specified. It indicates that the patient is experiencing a lasting effect from a spider bite that was intentionally inflicted by another party.

Apply this code when documenting a chronic condition, scar, or other permanent sequela directly attributable to an assault involving a spider bite. This is appropriate for follow-up encounters where the acute phase of the toxic effect has passed, but the patient continues to suffer from its lasting consequences.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela.
• Ensure documentation clearly links the current condition to the past spider venom exposure and specifies the assault nature.
• Do not use for initial encounters or active toxic effects; those require acute poisoning codes.
