Toxic effect of venom of centipede/millipede, undet, init

This code signifies an adverse reaction resulting from contact with the venom of a centipede or venomous millipede, where the intent (e.g., accidental, intentional self-harm) is not yet determined. The "initial encounter" designation indicates that the patient is receiving active treatment for the acute effects of the envenomation.

Apply this code when a patient presents with symptoms of envenomation from a centipede or venomous millipede, and the medical record does not specify whether the exposure was accidental, intentional, or due to assault. This is appropriate for the initial visit where the patient is being evaluated and treated for the immediate toxic effects.

• Ensure documentation clearly states the patient is experiencing toxic effects from centipede or venomous millipede venom.
• Only use the "A" seventh character for the very first encounter for this condition.
• If the intent of the exposure is later clarified (e.g., accidental), a more specific code should be used for subsequent encounters.
