Poisoning by vitamins, accidental (unintentional), subs

This code indicates a patient presenting for follow-up care or ongoing treatment related to an accidental overdose or toxic exposure to vitamins. The initial poisoning event has already occurred, and the patient is now in a recovery or management phase.

Apply this code when documenting subsequent visits for patients who previously experienced an unintentional vitamin poisoning. This includes appointments for monitoring organ function, managing lingering symptoms, or adjusting treatment plans after the initial acute phase.

• Ensure the encounter is not for the initial acute poisoning; use the appropriate initial encounter code for that.
• Verify documentation clearly states the poisoning was accidental and due to vitamins.
• Pair with codes for specific symptoms or complications resulting from the vitamin poisoning.
