Hypomagnesemia (ICD 10: E83.42) is a critical yet often overlooked electrolyte imbalance that can lead to severe complications if left untreated. Magnesium plays a vital role in nerve function, muscle contraction, and heart rhythm, making its deficiency a serious medical concern. This blog will explore Hypomagnesemia ICD 10 in detail, covering its causes, symptoms, diagnosis, and treatment. Whether you’re a healthcare provider, medical coder, or a patient seeking information, this guide will provide actionable insights and clarify coding nuances.
What is Hypomagnesemia?
Hypomagnesemia refers to abnormally low levels of magnesium in the blood (serum magnesium < 1.7 mg/dL). Since magnesium is essential for over 300 enzymatic reactions in the body, its deficiency can disrupt multiple systems.
Hypomagnesemia ICD 10 Code Breakdown
The ICD-10-CM code for Hypomagnesemia is E83.42, classified under:
- E83.4: Disorders of magnesium metabolism
- E83.42: Hypomagnesemia
This code is crucial for accurate medical billing, clinical documentation, and research purposes.
Causes of Hypomagnesemia
Hypomagnesemia can result from various factors, including:
1. Inadequate Dietary Intake
- Malnutrition
- Chronic alcoholism
- Prolonged fasting
2. Gastrointestinal Losses
- Chronic diarrhea
- Crohn’s disease
- Celiac disease
3. Renal Losses
- Diuretic use (loop and thiazide diuretics)
- Hypercalcemia
- Genetic disorders (e.g., Gitelman syndrome)
4. Endocrine Disorders
- Hyperaldosteronism
- Hyperparathyroidism
Symptoms of Hypomagnesemia
Symptoms can range from mild to life-threatening, including:
✅ Neuromuscular Symptoms
- Muscle cramps
- Tremors
- Seizures
✅ Cardiovascular Symptoms
- Arrhythmias (e.g., torsades de pointes)
- Prolonged QT interval
✅ Metabolic Symptoms
- Hypokalemia (low potassium)
- Hypocalcemia (low calcium)
Diagnosing Hypomagnesemia (ICD 10: E83.42)
Diagnosis involves:
- Serum Magnesium Test (Normal range: 1.7–2.2 mg/dL)
- 24-Hour Urinary Magnesium Excretion Test
- ECG Changes (e.g., prolonged PR and QT intervals)
| Test | Normal Range | Hypomagnesemia Indicator |
|---|---|---|
| Serum Magnesium | 1.7–2.2 mg/dL | < 1.7 mg/dL |
| Urinary Magnesium | 40–120 mg/day | < 40 mg/day (renal loss) |
Treatment Options for Hypomagnesemia
1. Oral Magnesium Supplements
- Magnesium oxide
- Magnesium citrate
2. Intravenous (IV) Magnesium
- For severe cases (e.g., arrhythmias, seizures)
- Dosage: 1–2 g MgSO₄ in 100 mL IV over 15–60 mins
3. Dietary Adjustments
- Increase intake of magnesium-rich foods:
- Spinach
- Almonds
- Avocados
Hypomagnesemia ICD 10 Coding Tips
Medical coders must ensure accuracy when documenting Hypomagnesemia ICD 10 (E83.42). Key considerations:
✔ Document the Underlying Cause (e.g., alcoholism, malabsorption)
✔ Use Additional Codes for Complications (e.g., hypokalemia, arrhythmias)
✔ Avoid Unspecified Codes When possible
Case Study: Real-World Example
Patient Profile:
- 55-year-old male with chronic alcoholism
- Symptoms: Muscle spasms, fatigue, irregular heartbeat
Diagnosis:
- Serum Mg: 1.4 mg/dL
- ECG: Prolonged QT interval
Treatment:
- IV magnesium sulfate (2 g)
- Oral magnesium supplementation
ICD 10 Code Assigned: E83.42 (Hypomagnesemia)
Preventing Hypomagnesemia: Key Strategies
- Monitor High-Risk Patients (e.g., those on diuretics, alcoholics)
- Encourage Magnesium-Rich Diets
- Regular Blood Tests for early detection
FAQ: Hypomagnesemia ICD 10
1. What is the ICD 10 code for Hypomagnesemia?
