Toxic effect of venom of Australian snake, accidental, init

This code signifies a toxic reaction resulting from an accidental bite or sting by an Australian snake species not specifically classified elsewhere. The patient is experiencing the initial phase of the toxic effects, such as localized pain, swelling, or systemic symptoms like nausea, dizziness, or neurological compromise, directly attributable to the venom.

Apply this code when documenting an accidental envenomation by an unspecified Australian snake, and the patient is presenting for the initial treatment of the toxic effects. This would include emergency department visits, initial hospital admissions, or first outpatient encounters for the snakebite.

• Always use an additional code from T80.21-T80.29 to specify the type of venom if known.
• Ensure the encounter is truly "initial" for the toxic effect; subsequent care would use a different seventh character.
• Confirm the snake is identified as Australian and not a more specific type with its own code (e.g., brown snake, tiger snake).
