Additional Info

• The parameters for coding hyponatremia are any of the following 3 items: (This change is active as of Feb 12, 2018)
  • Na+ < 120 OR
  • Any Na+ < 135 AND in the presence of signs or symptoms believed to be due to hyponatremia OR
  • Any Na+ < 135 with active treatment for hyponatremia

Only code the first occurrence, not each time it happens

• Main signs and symptoms of hyponatremia are:
  • CNS - altered sensorium, seizures, coma
  • GI - anorexia, nausea/vomiting (these occur early)
  • neuromuscular - muscle cramps, hyporeflexia

Alternate ICD10s to consider coding instead or in addition

• Disorder of mineral metabolism, NOS
• Syndrome of inappropriate secretion of antidiuretic hormone (SIADH)
• Polydipsia
• Headache NOS
• Seizure, NOS
• Coma NOS
• Adrenal insufficiency, NOS
• Hypothyroidism
