Poisoning by vitamins, intentional self-harm, init encntr

This diagnosis code signifies a patient presenting with adverse effects from an overdose of vitamins, where the overdose was deliberately self-inflicted. This indicates a suicidal or self-harm attempt involving vitamin toxicity.

Apply this code when documentation clearly states a patient intentionally ingested an excessive amount of vitamins, leading to poisoning symptoms. This is appropriate for the initial visit or encounter for this specific poisoning event.

• Ensure documentation explicitly states "intentional self-harm" or "suicide attempt" related to vitamin ingestion.
• Always assign an additional code for the specific vitamin involved, if known (e.g., E56.9 for vitamin deficiency, unspecified, if the specific vitamin is not documented).
• Remember the "A" at the end signifies an initial encounter for this poisoning episode.
