Toxic effect of taipan venom, accidental, sequela

This code signifies a long-term or residual health problem resulting from an accidental taipan snake envenomation. It indicates that the acute toxic effects have resolved, but the patient continues to experience lasting complications directly attributable to the venom exposure.

Apply this code when documenting conditions such as chronic neurological deficits, persistent organ damage (e.g., kidney, liver), or ongoing coagulopathy that are a direct consequence of a past, unintentional taipan bite. This code is appropriate for follow-up encounters addressing these enduring sequelae, not the initial acute poisoning.

• Requires a seventh character "S" to indicate sequela, meaning the patient is seen for the residual effects of the poisoning.
• Do not use for the initial acute poisoning episode; use the acute poisoning code (T63.031A) for that encounter.
• Always code the specific sequela (e.g., chronic kidney disease, peripheral neuropathy) first, followed by this code to indicate its etiology.
