- Serum magnesium testing is covered when hypomagnesemia is suspected due to gastrointestinal or renal losses or when patients present with symptoms of low magnesium (weakness, muscle cramps, confusion, irregular heartbeat, or seizures).
- Serum magnesium testing is covered for patients with conditions known to cause hypomagnesemia (examples include cardiac arrhythmias, proton pump inhibitor use, chronic alcohol use, uncontrolled diabetes mellitus, hypercalcemia, post–organ transplant status, inherited renal magnesium wasting, malabsorption syndromes, aminoglycoside or amphotericin B nephrotoxicity, cisplatin, pentamidine, calcineurin inhibitor therapy, digoxin use, prolonged IV or nasogastric therapy, parenteral alimentation with [...]
