Additional Info

  • The parameters for coding hypomagnesemia are any of the following 3 items: (This change is active as of Feb 12, 2018)
    • Mg++ < 0.5 OR
    • Any Mg++ < 0.8 AND in the presence of signs or symptoms believed to be due to hypomagnesemia OR
    • Any Mg++ < 0.8 with active treatment for hypomagnesemia
  • NOTE: While some listings of normal ranges for Mg++ are as low as 0.63, nonetheless the rules listed here are what should be used to code hypomagnesemia.
  • Main signs and symptoms of hypomagnesemia are:
    • neuromuscular - lethargy, weakness, neuromuscular irritability (fasciculations, tremors, tetany)
    • GI - anorexia, nausea/vomiting, ileus
    • cardiovascular - long QT, AV block, cardiac arrest, increased digoxin sensitivity, arrythmias
