Poisoning by vitamins, assault, subsequent encounter

This code signifies a patient presenting for follow-up care or sequelae related to a deliberate act of poisoning with vitamins. The initial acute phase of the poisoning has passed, and the patient is now being managed for ongoing effects or complications. This implies the vitamin overdose was inflicted by another person with harmful intent.

Apply this code when documenting subsequent encounters for a patient who was intentionally poisoned by vitamins. This includes visits for monitoring organ damage, managing persistent symptoms, or addressing psychological impacts stemming from the assault. Use it after the initial treatment for the acute poisoning has been rendered.

• Ensure documentation clearly states the poisoning was an assault and not accidental or self-harm.
• Confirm this is a subsequent encounter; for the initial encounter, a different seventh character would be used.
• Always code the specific vitamin involved if known and documented, using a more specific code from the T45.2 category.
