Toxic effect of oth seafood, intentional self-harm, subs

This code signifies a patient presenting for follow-up care related to poisoning from seafood other than ciguatera or scombroid, where the ingestion was a deliberate act of self-harm. The patient is no longer in the acute phase of the toxic effect but is receiving ongoing treatment or monitoring.

Apply this code when documenting a patient's return visit for complications, monitoring, or continued management of a toxic reaction to miscellaneous seafood, such as shellfish or other fish, that was intentionally consumed with the intent to cause self-harm. This includes scenarios where the patient is being seen for psychiatric evaluation, organ damage assessment, or ongoing supportive care after the initial acute presentation.

• Always sequence this code after the primary mental health diagnosis for intentional self-harm.
• Ensure documentation clearly specifies the "subsequent encounter" status, indicating care beyond the initial acute treatment.
• Verify the seafood involved is not ciguatera or scombroid, as those have specific codes.
