Toxic effect of coral snake venom, undetermined, subs encntr

This code signifies the adverse systemic effects resulting from exposure to coral snake venom, where the intent (accidental, intentional self-harm, assault) cannot be determined. It is used when a patient is receiving follow-up care for such an exposure after the initial treatment phase.

Apply this code for patients presenting for ongoing management, monitoring, or treatment of complications arising from coral snake envenomation, when the circumstances of the bite are unclear. This includes follow-up appointments for wound care, neurological deficits, or other systemic effects after the acute phase has passed.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care.
• Do not use for initial encounters or for sequelae (late effects) once the toxic effect has resolved.
• Always sequence this code after any codes for specific manifestations or complications of the envenomation.
