Toxic effect of venom of Australian snake, undet, init

This code signifies a patient presenting with an adverse systemic reaction due to envenomation by an unspecified Australian snake, where the intent (accidental vs. intentional) of the exposure is not yet determined. The patient is in the initial phase of treatment for this toxic effect.

Use this code for emergency department visits or initial hospital admissions where a patient has been bitten by an Australian snake, and the specific type of snake is unknown or not documented. It applies when the patient is experiencing symptoms of envenomation and the encounter is the first time they are receiving care for this specific incident.

• Ensure documentation clearly states "Australian snake" and that the specific type is not identified.
• The "A" seventh character indicates an initial encounter, meaning the patient is actively receiving treatment for the acute effects.
• If the intent of the exposure is later determined (e.g., accidental, intentional self-harm), a more specific code should be used for subsequent encounters.
