Riboflavin deficiency

This code represents a nutritional deficiency specifically involving riboflavin, also known as vitamin B2. Riboflavin is essential for cellular growth and function, and its deficiency can manifest with symptoms affecting the skin, eyes, and mucous membranes.

Assign this code when documentation clearly indicates a diagnosis of riboflavin deficiency, often presenting with cheilosis, angular stomatitis, glossitis, or ocular symptoms like conjunctivitis. Supporting documentation should include clinical findings, dietary history, and potentially laboratory confirmation of low riboflavin levels.

• Ensure the documentation explicitly states "riboflavin deficiency" or "vitamin B2 deficiency."
• Do not confuse with other B vitamin deficiencies; each has a specific code.
• Consider co-occurring malnutrition codes if the deficiency is part of a broader nutritional issue.
