Magnesium Deficiency
Learn about magnesium deficiency diagnosis including clinical manifestations, lab tests like serum magnesium, and ICD-10-CM code E53.0. This resource provides information on hypomagnesemia symptoms, causes, treatment, and documentation best practices for healthcare professionals. Explore relevant medical coding guidelines and clinical documentation improvement strategies for accurate magnesium deficiency diagnosis and reporting.
Low magnesium levels in the blood, often causing various symptoms.
Muscle cramps, weakness, tremors, fatigue, nausea, loss of appetite, personality changes.
Hospitalized patients, GI disorders, alcoholism, diuretic use, malnutrition.
ICD-10 Code Families
Complete code families applicable to E83.42
When to use each related code
| Description | When to use |
|---|---|
| Magnesium deficiency | Low magnesium levels confirmed by lab tests, with associated symptoms like muscle cramps or weakness. |
| Hypocalcemia | Low calcium levels in blood tests, potentially causing muscle spasms, tetany, or seizures. Consider alongside magnesium deficiency. |
| Hypokalemia | Low potassium levels in blood, causing muscle weakness, fatigue, or cardiac arrhythmias. May accompany magnesium deficiency. |
Best-practice checklist
- ✓Document serum magnesium levels (mg/dL)
- ✓Specify method used for magnesium testing
- ✓Detail symptoms related to hypomagnesemia
- ✓Document any contributing factors or medications
- ✓Note treatment plan, including magnesium supplementation
Best-practice tips
- 01Document serum magnesium levels with ICD-10-CM code E83.5.
- 02Correlate symptoms, like tremors or weakness, for accurate CDI of hypomagnesemia.
- 03Order Mg tests for at-risk patients (e.g., diuretic use) for compliant documentation.
- 04Review medication list for drug-induced Mg loss and document appropriately for compliance.
- 05Ensure proper charting of Mg replacement therapy and monitor patient response for CDI.
Step-by-step checklist

3. Review medications (e.g., diuretics, PPIs)
- 4
4. Evaluate dietary intake and GI function
Ready-to-paste narrative
Patient presents with symptoms suggestive of hypomagnesemia, including muscle cramps, tremors, weakness, and fatigue. Additional symptoms reported include tetany, seizures, ataxia, and cardiac arrhythmias. Patient history includes (mention relevant medical history contributing to magnesium deficiency, e.g., diuretic use, Crohn's disease, alcoholism, malnutrition, PPI use). Laboratory results confirm magnesium deficiency with a serum magnesium level of (insert value) mgdL, below the normal range. Electrolyte panel reveals (mention other electrolyte imbalances if present, e.g., hypokalemia, hypocalcemia). ECG findings (mention relevant ECG findings if obtained, e.g., prolonged QT interval). Assessment: Magnesium deficiency (ICD-10-CM code: E83.5). Differential diagnoses considered include other electrolyte imbalances, neuromuscular disorders, and endocrine disorders. Plan: Oral magnesium supplementation prescribed at (dosage) (frequency). Dietary counseling provided regarding magnesium-rich foods. Patient education provided on symptoms of hypomagnesemia and importance of medication adherence. Follow-up magnesium level check scheduled in (duration) to monitor response to therapy and adjust dosage as needed. Patient advised to return sooner if symptoms worsen or new symptoms develop. Prognosis is generally good with appropriate magnesium replacement therapy.
