Definition:
CPT® code 84144 describes a laboratory test used to measure magnesium levels in the blood or serum. Magnesium testing is important for assessing electrolyte balance, evaluating neuromuscular or cardiac function, and monitoring patients at risk for deficiency or excess.
When to Use:
- For patients presenting with muscle weakness, cramps, or cardiac arrhythmias.
- To monitor electrolyte balance in patients on diuretics, IV fluids, or other medications affecting magnesium levels.
- As part of a routine metabolic panel or targeted testing when deficiency or imbalance is suspected.

To support billing for CPT® 84144, clinicians should document:
- Medical necessity, including symptoms, risk factors, or underlying conditions.
- Relevant patient history and prior lab results.
- Any follow-up plan based on magnesium levels, such as supplementation or medication adjustments.
