Toxic effect of contact w unsp venom animal, acc, sequela

This code signifies the long-term or residual effects resulting from an accidental exposure to venom from an unidentified animal. These sequelae are persistent conditions that manifest after the initial acute phase of the envenomation has passed. The original venomous animal responsible for the exposure could not be identified.

Apply this code when documenting chronic pain, neurological deficits, tissue damage, or other lasting health problems directly attributable to an accidental, unspecified venomous bite or sting. This is appropriate for follow-up encounters addressing these persistent issues, not the initial acute treatment.

• Only use this code for the sequelae (late effects), not the initial acute toxic effect.
• Ensure documentation clearly states the venomous animal was "unspecified" and the exposure was "accidental."
• Always code the specific nature of the sequela (e.g., chronic pain, scar) in addition to this code.
