Toxic effect of contact w venom marine plant, acc, sequela

This code signifies a long-term or late-occurring health problem resulting from an accidental exposure to a venomous marine plant. This could include chronic skin conditions, persistent neurological symptoms, or other lasting effects that manifest after the initial acute phase of the poisoning has resolved. The original contact was unintentional, such as brushing against a toxic seaweed or coral.

Apply this code when documenting a patient presenting with a chronic or residual condition directly attributable to a past, accidental encounter with a venomous marine plant. This is appropriate for follow-up visits where the focus is on managing the lasting consequences, rather than the acute poisoning event itself. Examples include persistent dermatitis or nerve damage years after the initial exposure.

• Always ensure documentation clearly links the current sequela to a past, accidental venomous marine plant exposure.
• Do not use this code for the initial acute poisoning event; instead, use the appropriate acute toxic effect code.
• This "S" seventh character indicates a sequela, meaning the residual effect of a past condition.
