Find comprehensive information on low magnesium (hypomagnesemia) diagnosis, including clinical manifestations, lab tests (serum magnesium), ICD-10 codes (E83.4), differential diagnosis, and treatment options. This resource offers guidance for healthcare professionals on proper documentation, medical coding best practices, and optimizing patient care related to magnesium deficiency. Learn about the causes, symptoms, and management of hypomagnesemia for accurate clinical documentation and coding.
Also known as
Hypomagnesemia
Abnormally low level of magnesium in the blood.
Electrolyte imbalance NOS
Unspecified electrolyte imbalance, including possible low magnesium.
Hyponatremia
Low sodium levels, sometimes associated with magnesium deficiency.
Other electrolyte abnormalities
Includes other unspecified electrolyte imbalances like low magnesium.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the low magnesium due to a drug (medicinal)?

Coding E83.5 (hypomagnesemia) without specifying cause (e.g., inadequate intake, malabsorption) risks underpayment and inaccurate clinical data.
Failing to document the relationship between Chronic Kidney Disease (CKD) and magnesium levels leads to coding errors and missed secondary diagnoses.
Omitting documentation of medications like diuretics or proton pump inhibitors as a cause of low magnesium impacts accurate coding and quality reporting.
Patient presents with symptoms suggestive of hypomagnesemia, including muscle cramps, weakness, tremors, and tetany. Additional symptoms such as fatigue, nausea, loss of appetite, and personality changes may also be present. Patient reports (insert patient-reported information related to dietary intake, medication use, and relevant medical history, e.g., history of Crohn's disease, diuretic use, or alcoholism). Physical examination reveals (insert relevant findings, e.g., hyperreflexia, Chvostek's sign, Trousseau's sign). Serum magnesium level is (insert value, e.g., 1.2 mgdL), confirming the diagnosis of hypomagnesemia or low magnesium. Differential diagnosis includes other electrolyte imbalances such as hypokalemia and hypocalcemia. ECG may show prolonged QT interval. Treatment plan includes magnesium supplementation with (specify route and dosage, e.g., oral magnesium oxide 400 mg twice daily) and addressing underlying causes. Patient education provided on magnesium-rich foods and potential medication interactions. Follow-up magnesium level to be checked in (specify timeframe, e.g., one week) to assess treatment efficacy and monitor for magnesium toxicity. ICD-10 code E83.4 (hypomagnesemia) is documented.
