Toxic effect of contact w oth venomous amphib, acc, sequela

This code signifies a long-term or late-occurring health problem resulting from an accidental exposure to toxins from a venomous amphibian other than a toad. This could include persistent neurological issues, chronic skin conditions, or organ damage that manifests after the initial acute phase of the poisoning has resolved.

Apply this code when documenting a condition that is a direct consequence of a past, unintentional toxic exposure to a venomous amphibian. This is appropriate for follow-up encounters where the sequelae are being managed, rather than the initial acute poisoning event.

• Requires a seventh character "S" to indicate sequela, meaning the residual effect of a past injury or illness.
• Do not use for the initial acute toxic effect; a different code from the T63.83 category would be appropriate for the acute phase.
• Always code the specific sequela (e.g., chronic dermatitis, peripheral neuropathy) first, followed by this code to indicate its etiology.
