Toxic effect of venom of caterpillars, assault, init encntr

This code describes the adverse systemic or localized reactions resulting from contact with venomous caterpillars, specifically when the exposure is due to an intentional act of harm by another person. The "initial encounter" designation indicates that this code is used for the period in which the patient is receiving active treatment for the toxic effect.

Use this code when documenting a patient presenting with symptoms such as dermatitis, pain, swelling, or systemic reactions (e.g., nausea, headache) directly attributable to caterpillar venom. This code is specifically for cases where the exposure was an assault, meaning it was inflicted intentionally by another individual.

• Always assign an external cause code (e.g., X23.-) to provide further detail about the specific type of caterpillar and the circumstances of the assault.
• Do not use this code for accidental exposures or self-inflicted injuries; different codes exist for those scenarios.
• Ensure documentation clearly specifies the "assault" nature of the encounter to justify using this specific subcategory.
