Hypervitaminosis A

This code describes a toxic condition resulting from excessive intake of vitamin A, leading to a range of symptoms affecting various organ systems. It can manifest acutely or chronically, with symptoms such as headache, nausea, vomiting, blurred vision, skin changes, and liver dysfunction.

Assign this code when documentation clearly indicates a diagnosis of vitamin A toxicity, whether from over-supplementation or excessive dietary intake. Supporting documentation should include clinical findings consistent with hypervitaminosis A and, ideally, laboratory confirmation of elevated vitamin A levels.

• Differentiate acute from chronic hypervitaminosis A if specified in the documentation, though this code covers both.
• Do not confuse with vitamin A deficiency (E50.-), which is a distinct nutritional disorder.
• Code any associated symptoms or complications (e.g., elevated liver enzymes, pseudotumor cerebri) in addition to this code.
