Toxic effect of contact w oth venomous animals, undet, subs

This code signifies a harmful systemic reaction resulting from exposure to venom from an unspecified animal, excluding snakes, spiders, scorpions, or marine animals. The "undetermined" aspect indicates that the specific animal responsible for the venomous contact is not identified in the medical record.

Apply this code for follow-up care of a patient experiencing ongoing symptoms or complications from a venomous animal encounter where the type of animal is unknown. This is appropriate for subsequent visits after initial treatment, such as for wound care, monitoring for delayed reactions, or managing persistent systemic effects.

• Ensure the encounter is for follow-up care, not the initial treatment.
• Confirm the documentation explicitly states "undetermined" or "unspecified" regarding the venomous animal.
• Do not use if the venomous animal is identified as a snake, spider, scorpion, or marine animal; use more specific codes instead.
