Electrolyte disturbance

• Upon our implementation on 1/1/2019 to ICD10-based diagnostic coding, we have gone through several version of coding of electrolyte disturbances (in which we include hypoalbuminemia)
  • Originally, we had "double threshold" values -- i.e. more extreme numerical thresholds without symptoms attributable to the disturbance, and less extreme threshold in those with symptoms
  • Second, for a brief period in 2024/25, we switched to just the single, more extreme numerical threshold irrespective of symptoms.
  • Now, as of April 2025, we have altered the paradigm
• The new paradigm has 2 aspects:
  • (1) More extreme numerical thresholds for specific disturbances, to be coded without reference to symptoms or not. The threshold values are listed in each of the specific ICD10 codes.
    • In regard to this, we have eliminated Hypoalbuminemia, severe; altered the names of these entities to remove the words "severe" and/or "symptomatic"; and changed the serum phosphate disturbance from including both low and high values, to only now include low values (since hyperphosphatemia is almost never a clinically important problem).
  • (2) If a patient has symptomatic disturbance, the new rule is to code the disturbance(s) (e.g. Coma NOS, Rhabdomyolysis, Ventricular fibrillation), and link that diagnosis to Electrolyte disorder, NOS
