Additional Info

• The parameter for coding hypomagnesemia is the following: (This change is active as of Feb 27,2025)
  • Mg++ <= 0.41
• 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
  • miscellaneous - hypocalcemia, hypokalemia, vertigo

Alternate ICD10s to consider coding instead or in addition

• Tetany
• Disorder of mineral metabolism, NOS
• Hypoparathyroidism
• Electrolyte disorder, NOS
• Disorder of ocular muscles
• Seizure, NOS
• Ventricular tachycardia
• Effects of starvation

Candidate Combined ICD10 codes

• Tetany
