Essential fatty acid [EFA] deficiency

This code signifies a nutritional deficiency specifically related to essential fatty acids, which are crucial for various bodily functions including cell membrane integrity, hormone production, and immune response. It indicates that the patient's body is not receiving or properly utilizing adequate amounts of these vital fats, such as linoleic acid (omega-6) and alpha-linolenic acid (omega-3).

Use this code when documentation clearly indicates a diagnosis of essential fatty acid deficiency, often presenting with symptoms like dermatitis, poor growth, visual disturbances, or neurological issues. This diagnosis is typically supported by dietary history, clinical signs, and sometimes laboratory testing showing low levels of specific fatty acids.

• Ensure documentation specifies "essential" fatty acid deficiency; general fatty acid deficiency may require further specificity.
• Consider co-occurring malnutrition codes (e.g., E44-E46) if the EFA deficiency is part of a broader nutritional deficit.
• Review for any underlying conditions causing malabsorption or increased EFA requirements that might need separate coding.
