E61.3 Manganese deficiency

Name of the Condition

• Manganese Deficiency
• Also referred to as hypomagnesemia (not to be confused with magnesium deficiency).

Summary

Manganese deficiency is a condition characterized by insufficient levels of manganese, an essential trace mineral required for enzyme function, bone formation, and metabolic processes. Deficiency may result from inadequate dietary intake, impaired absorption, or increased physiological demands. Manganese plays a role in antioxidant defense and connective tissue health.

Causes

Causes can include insufficient dietary manganese intake, malabsorption disorders (e.g., inflammatory bowel disease), chronic liver disease, or excessive intake of other minerals (e.g., iron, calcium) that interfere with manganese absorption. Certain medications or gastrointestinal surgeries may also reduce manganese availability.

Risk Factors

• Poor dietary intake of manganese-rich foods (e.g., nuts, whole grains, leafy greens)
• Malabsorption syndromes (e.g., celiac disease, Crohn's disease)
• Chronic alcohol use
• Gastrointestinal surgeries (e.g., bariatric procedures)
• Premature birth or low birth weight
• Chronic kidney disease or dialysis

Symptoms

• Impaired growth or bone development (in severe cases)
• Dermatological changes (e.g., skin rash, brittle nails)
• Neurological symptoms (e.g., dizziness, poor coordination)
• Metabolic disturbances (e.g., altered glucose tolerance)
• Reduced immune function

Diagnosis

Diagnosis typically involves measuring serum or whole-blood manganese levels, along with clinical evaluation of symptoms and dietary history. Additional tests may assess for underlying malabsorption or metabolic disorders. Imaging or functional tests may be used to evaluate related complications.

Treatment Options

• Dietary modifications to include manganese-rich foods (e.g., teas, spices, legumes)
• Manganese supplementation (oral or intravenous, as clinically indicated)
• Management of underlying conditions affecting absorption or metabolism
• Monitoring for signs of toxicity, as excessive intake can be harmful

Prognosis and Follow-Up

With appropriate treatment, most individuals recover without long-term effects. Follow-up may include periodic monitoring of manganese levels and symptom resolution. Chronic deficiency may require ongoing dietary or supplementation management, especially in cases with persistent absorption issues.

Complications

• Severe growth retardation (in pediatric cases)
• Persistent neurological or dermatological symptoms
• Increased susceptibility to infections
• Worsening of underlying conditions (e.g., malabsorption syndromes)

Lifestyle & Prevention

• Consume a balanced diet with manganese-rich foods (e.g., whole grains, nuts, green vegetables)
• Avoid excessive intake of minerals that interfere with manganese absorption (e.g., high-dose iron or calcium supplements)
• Address underlying gastrointestinal or metabolic conditions promptly
• Limit alcohol consumption, which may impair manganese utilization

When to Seek Professional Help

Seek medical attention if you experience unexplained fatigue, neurological symptoms, or growth concerns, especially with a history of malabsorption or restrictive diets. Prompt evaluation is important for at-risk populations (e.g., infants, the elderly, or those with chronic illnesses).

Tips for Medical Coders

• Use E61.3 for confirmed manganese deficiency, ensuring documentation supports clinical findings (e.g., lab results, symptom correlation).
• Differentiate from other nutrient deficiencies (e.g., iron, copper) by verifying specific manganese-related symptoms or lab values.
• Document underlying causes (e.g., malabsorption, dietary insufficiency) when applicable to support code specificity.
• Avoid using E61.3 for general nutritional deficiencies without manganese-specific evidence.
