Poisoning by vitamins, not elsewhere classified

This code signifies an adverse health effect resulting from the ingestion or exposure to an excessive amount of one or more vitamins. It encompasses toxic reactions or overdose symptoms caused by vitamin intake that is not otherwise specified as accidental or intentional self-harm.

Apply this code when documentation clearly indicates a patient presenting with signs and symptoms of vitamin toxicity, such as hypervitaminosis A, D, or B6, due to an overdose. This code is appropriate when the intent (e.g., accidental, intentional) is not specified or when the poisoning is due to therapeutic misadventure.

• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Do not use this code if the poisoning is explicitly documented as accidental (E858.8) or intentional self-harm (E950.6).
• Ensure the medical record specifies "poisoning" or "toxicity" due to vitamins, not just an adverse effect or intolerance.
