E56: Other vitamin deficiencies

E56 refers to Other vitamin deficiencies, a nutritional deficiency that can result from inadequate dietary intake, malabsorption, chronic disease, or increased physiological needs. These deficiencies affect growth, immune function, neurological health, bone development, and overall well-being.

Symptoms

• Night blindness or dry eyes – From vitamin A deficiency
• Fatigue or irritability – Seen in B-complex and vitamin C deficiencies
• Bone pain or rickets – Associated with vitamin D or calcium deficiencies
• Dermatitis or diarrhea – Typical of niacin or zinc deficiency
• Impaired wound healing – Seen with vitamin C and zinc deficiencies
• Neurological symptoms – Linked to thiamine, B12, or selenium deficits
• Residual developmental issues – From E64 sequelae of past malnutrition

Diagnosis

Diagnosis of Other vitamin deficiencies includes blood tests for micronutrient levels, dietary intake assessment, physical examination, and in some cases, genetic testing for absorption disorders. Chronic malnutrition history may also guide diagnostic interpretation.

ICD10 Code Usage

ICD10 code E56 is widely used in internal medicine, pediatrics, geriatrics, and public health settings to track vitamin and mineral deficiencies. It supports clinical nutrition planning, supplementation protocols, and documentation for insurance and epidemiology.

FAQs

Q1: What is ICD10 code E56?
A: It is used to document Other vitamin deficiencies, a deficiency of vitamins or essential nutrients critical for body function.

Q2: What causes nutrient deficiencies?
A: Poor diet, malabsorption syndromes, chronic illness, alcohol use disorder, or lack of sun exposure (for vitamin D).

Q3: Are these deficiencies reversible?
A: Most are correctable with targeted dietary changes and supplementation.

Q4: Who is most at risk?
A: Children, elderly, pregnant women, and individuals with gastrointestinal disorders or restrictive diets.

Q5: How are they treated?
A: Oral or IV supplements, fortified foods, and addressing the underlying condition causing malnutrition.

Conclusion

ICD10 code E56 enables the accurate diagnosis and management of Other vitamin deficiencies. Proper coding ensures effective nutritional interventions, improves health outcomes, and facilitates public health initiatives targeting malnutrition and micronutrient deficiency.
