Toxic effect of venom of African and Asian snake, acc, init

This code signifies an adverse health effect resulting from an accidental exposure to venom from a non-specified African or Asian snake, excluding those with more specific ICD-10-CM codes. The patient is experiencing the initial phase of the toxic reaction, requiring active treatment.

Use this code when a patient presents with symptoms of envenomation (e.g., pain, swelling, systemic effects) following an unintentional bite from an African or Asian snake not otherwise classified. This applies to the initial visit for assessment and management of the acute toxic effects.

• Requires an external cause code (e.g., W59.21XA for bite by nonvenomous snake, initial encounter) to fully describe the incident.
• Do not use for intentional self-harm or assault; those scenarios require different intent characters.
• Ensure the snake is identified as African or Asian and not covered by a more specific venom code.
