Toxic effect of unsp spider venom, undetermined, init encntr

This code signifies a patient presenting with adverse health effects resulting from exposure to spider venom, where the specific type of spider is unknown. The circumstances surrounding the exposure are also unclear, meaning it cannot be definitively classified as accidental, intentional self-harm, assault, or therapeutic misadventure.

This code is appropriate for initial encounters when a patient seeks medical attention for symptoms consistent with a spider bite, but the spider responsible has not been identified. It is also used when the intent behind the exposure (e.g., accidental vs. intentional) cannot be determined from the available documentation.

• Always seek more specific documentation regarding the spider type and intent if available.
• This code is for the initial encounter; subsequent encounters will require a different 7th character.
• Do not use if the spider is identified (e.g., black widow, brown recluse) or if the intent is clearly documented.
