Hypervitaminosis A

This code represents a toxic condition resulting from excessive intake or accumulation of vitamin A in the body. It can manifest with a range of symptoms affecting the skin, bones, liver, and central nervous system, varying in severity based on the duration and amount of overdose.

Use this code when documentation clearly indicates a diagnosis of vitamin A toxicity, whether acute or chronic. This typically occurs due to over-supplementation or excessive consumption of vitamin A-rich foods, and is supported by laboratory findings of elevated serum retinol levels and characteristic clinical signs.

• Differentiate from vitamin A deficiency, which is coded elsewhere.
• Ensure documentation specifies "hypervitaminosis A" rather than just "elevated vitamin A levels" if symptoms are not present.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it's an underlying cause of other documented conditions.
