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

This code signifies a toxic reaction resulting from an intentional snakebite by a non-specified snake, occurring during the recovery phase of the injury. It indicates that the patient is receiving follow-up care for the sequelae or complications of the initial envenomation, rather than the initial acute treatment.

Apply this code when documenting subsequent encounters for a patient who was deliberately bitten by an unidentifiable or unspecified snake, and is now being treated for ongoing symptoms, complications, or long-term effects of the venom. This includes follow-up visits for wound care, monitoring for delayed systemic effects, or management of chronic pain or tissue damage.

• Requires an external cause code (X90-Y09) to fully describe the assault.
• Distinguish from initial encounters (A) or sequela encounters (S) based on the patient's stage of care.
• Ensure the medical record clearly documents the "assault" intent and the "subsequent encounter" status.
