Toxic effect of ingested (parts of) plant(s), slf-hrm, subs

This code signifies a toxic reaction resulting from the deliberate ingestion of plant material, excluding fungi, with the intent to cause self-harm. The patient is no longer in the initial phase of treatment for the poisoning but is receiving follow-up care for complications or ongoing management related to the self-inflicted plant toxicity.

Apply this code when documenting subsequent encounters for patients who have previously presented with a toxic effect from intentionally ingesting plants (e.g., oleander, castor beans, jimsonweed) as a suicide attempt or gesture. This includes follow-up appointments for organ damage assessment, psychiatric evaluation, or ongoing treatment of residual symptoms after the acute poisoning has been addressed.

• Ensure documentation clearly specifies "intentional self-harm" and that the substance was a plant (not a fungus or other chemical).
• Confirm the encounter is for follow-up care, not the initial acute treatment.
• Always code any specific manifestations of the toxicity (e.g., cardiac arrhythmias, gastrointestinal distress) in addition to this code.
