Toxic effect of contact w oth venom animals, undet, sequela

This code signifies a long-term or residual health problem resulting from exposure to the venom of an unspecified venomous animal, where the intent (accidental, intentional self-harm, assault, undetermined) is not documented. It indicates that the acute phase of the toxic effect has passed, but lasting complications persist.

Use this code for patients presenting with chronic symptoms or conditions directly attributable to a past, undifferentiated venomous animal encounter. This is appropriate when the initial injury occurred in the past and the patient is now being treated for the ongoing sequelae, and the specific animal or intent of exposure remains unknown.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic pain, neurological deficit).
• Ensure documentation clearly links the current condition to a past venomous animal exposure, even if the animal type is not specified.
• Avoid using this code for acute toxic effects; instead, use the appropriate acute toxic effect code with the 7th character "A" (initial encounter) or "D" (subsequent encounter).
