Toxic eff of harmful algae and algae toxins, slf-hrm, sqla

This code signifies the long-term or residual health problems resulting from a deliberate act of self-poisoning using harmful algae or their toxins. It indicates that the acute phase of the toxic exposure has passed, but the patient continues to experience lasting effects. These sequelae could include chronic organ damage, neurological deficits, or persistent gastrointestinal issues.

Apply this code when documenting conditions that are direct, lasting consequences of a previous intentional self-harm attempt involving harmful algae or their toxins. This would be used after the initial acute treatment for the poisoning has concluded, and the patient is being managed for chronic complications. Examples include chronic liver failure or persistent neurological symptoms attributed to the past toxic exposure.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving algae toxins.
• Do not use for acute toxic effects; refer to the appropriate acute poisoning codes for initial encounters.
