ICD Code E83.42

ICD code E83.42 is a classification used to identify and document the medical condition known as hypomagnesemia. This condition refers to an abnormally low level of magnesium in the blood, which can lead to various health issues such as muscle cramps, fatigue, and cardiac arrhythmias. In the context of healthcare revenue cycle management, accurate coding of hypomagnesemia is crucial for proper billing and reimbursement processes, ensuring that healthcare providers receive appropriate compensation for the diagnosis and treatment of this condition.

1. Low Serum Magnesium Levels: Use the ICD code when laboratory tests confirm magnesium levels below the normal reference range, typically less than 1.7 mg/dL.

2. Neuromuscular Symptoms: Document the presence of neuromuscular irritability, such as muscle cramps, tremors, or spasms, which may indicate a deficiency in magnesium.

3. Cardiovascular Manifestations: Identify any cardiac arrhythmias or palpitations that could be linked to low magnesium levels, as these are critical indicators for using the ICD code.

4. Neurological Symptoms: Note any neurological disturbances, including confusion, seizures, or vertigo, which can be associated with hypomagnesemia.

5. Gastrointestinal Symptoms: Record any gastrointestinal issues such as nausea, vomiting, or diarrhea that may contribute to or result from low magnesium levels.

6. Chronic Conditions: Consider the ICD code if the patient has chronic conditions like diabetes or alcoholism, which are known risk factors for magnesium deficiency.

7. Medication Use: Evaluate the use of medications such as diuretics or proton pump inhibitors, which can lead to decreased magnesium levels and warrant the use of the ICD code.

8. Electrolyte Imbalance: Use the ICD code when there is evidence of concurrent electrolyte imbalances, such as hypokalemia or hypocalcemia, often seen with hypomagnesemia.

9. Renal Function: Assess renal function, as impaired kidney function can lead to magnesium loss and justify the use of the ICD code.

10. Dietary Intake: Consider the patient's dietary history, particularly if there is evidence of inadequate magnesium intake through diet, which may necessitate the use of the ICD code.

For the ICD code E83.42, which pertains to hypomagnesemia, the relevant CPT codes that may be applicable for treatment or management include:

1. CPT 80048 - Basic metabolic panel (Calcium, total).

2. CPT 80053 - Comprehensive metabolic panel.

3. CPT 83735 - Magnesium; blood test.

4. CPT 96365 - Intravenous infusion, for therapy, prophylaxis, or diagnosis; initial, up to 1 hour.

5. CPT 96366 - Intravenous infusion, for therapy, prophylaxis, or diagnosis; each additional hour.

These CPT codes are typically used for diagnostic testing and treatment procedures related to monitoring and managing magnesium levels in the blood. It's important for healthcare providers to select the appropriate CPT codes based on the specific services rendered and the clinical context.
