Toxic effect of unsp snake venom, accidental, sequela

This code signifies the long-term or residual effects resulting from an accidental exposure to an unspecified snake venom. It is used when the acute phase of the envenomation has passed, but the patient continues to experience health problems directly attributable to the past toxic event.

Apply this code when documenting chronic conditions, disabilities, or persistent symptoms that are a direct consequence of a previous, unintentional snakebite where the specific type of snake venom was not identified. Examples include ongoing neurological deficits, chronic pain, or tissue damage that developed after the initial envenomation.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past, accidental, unspecified snake envenomation.
• Avoid using this code for acute envenomation; instead, use the appropriate acute toxic effect code.
