Toxic effect of coral snake venom, accidental, sequela

This code signifies the long-term or residual health problems that arise from an accidental coral snake envenomation. These sequelae can manifest as chronic neurological deficits, persistent tissue damage, or other lasting complications after the acute phase of the poisoning has resolved. It indicates that the patient is experiencing ongoing effects directly attributable to the venom exposure.

Apply this code when documenting follow-up care for a patient who previously suffered an unintentional coral snake bite and is now presenting with chronic conditions or lasting impairments. This would include scenarios such as ongoing nerve damage, muscle weakness, or organ dysfunction that developed as a direct result of the venom's toxic effects. It is used after the initial acute treatment for the envenomation has concluded.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., a code for neuropathy).
• Ensure documentation clearly links the current condition to the past coral snake envenomation.
• Verify the "S" seventh character is appropriate, indicating a sequela, rather than an initial encounter or subsequent encounter for the acute poisoning.
