Toxic effect of ingested (parts of) plant(s), undet, subs

This code signifies a toxic reaction resulting from the ingestion of an unspecified plant or plant part, where the intent (accidental, intentional self-harm, assault) cannot be determined. The patient is presenting for follow-up care or treatment of residual effects after the initial acute phase of the poisoning.

Use this code for patients returning for ongoing management of symptoms or complications stemming from a previous plant ingestion, when the specific plant is unknown and the circumstances surrounding the ingestion are not documented. This applies when the initial acute treatment has concluded, and the patient is in a recovery or monitoring phase.

• Ensure documentation clearly indicates a subsequent encounter for the toxic effect, not the initial presentation.
• Only use this code when the specific plant ingested is not identified and the intent is undetermined.
• Always sequence this code after any codes for the specific manifestations or complications of the toxic effect.
