Magnesium deficiency

This code represents a state where the body has insufficient levels of magnesium, an essential mineral involved in numerous biochemical reactions. It can manifest with a variety of symptoms affecting neuromuscular, cardiovascular, and metabolic functions. This condition is also known as hypomagnesemia.

Apply this code when documentation explicitly states a diagnosis of magnesium deficiency or hypomagnesemia. This is appropriate for patients presenting with symptoms such as muscle cramps, tremors, arrhythmias, or fatigue, where laboratory tests confirm low serum magnesium levels. It is also used when magnesium deficiency is identified as a contributing factor to other medical conditions.

• Do not confuse with hypermagnesemia (excess magnesium), which has a different code.
• Look for documentation of laboratory results confirming low magnesium levels to support this diagnosis.
• Consider coding any underlying cause of the magnesium deficiency, such as malabsorption or chronic kidney disease, if documented.
