Additional Info

• The parameters for coding hypercalcemia (using total serum calcium) is the following:
  • Ca++ >= 3.3
  • ionized Ca++ >=1.6

• Main signs and symptoms of hypercalcemia are:
  • GI - anorexia, nausea\vomiting, constipation, abdominal pain, increased acid production (dyspepsia, PUD), pancreatitis
  • Neuromuscular - weakness, proximal myopathy, decreased tone, decreased DTRs
  • CNS - CNS depression ( lethargy, confusion * coma), ataxia, abnormal EEG, depression, psychosis
  • Cardiovascular - hypertension, short QT interval, bradycardia, arrythmias
  • Renal - nephrogenic D.I., calcium nephropathy (stones, nephrocalcinosis, azotemia)
  • Miscellaneous - metastatic calcification

See https://ccmdb.kuality.ca/index.php?title=Hypocalcemia&curid=5880&diff=136294&oldid=125421

Serum corrected calcium is not reported. Instead if there is a concern for hyper/hypocalcemia an ionized calcium is now recommended.

Repeated events

If this happens repeatedly during the same ward or unit stay, only code it the first time it happens, regardless of whether it is an Admit Diagnosis or Acquired Diagnosis, rather than each time it happens. See ICD10 codes only coded the first time for other diagnoses coded this way.

Example:

A person has a self-limited episode of A-fib. It goes away and then recurs. Only code the first one. A person has a self-limited episode of A-fib. It goes away but then he has an episode of V-tach. As this is a different diagnosis, both of these should be listed, but only code once each. Patient comes in with hypokalemia. It’s treated and remits, but the next day it recurs. Only code the first time.

Alternate ICD10s to consider coding instead or in addition

• Hyperparathyroidism
• Parathyroid disorder, NOS
• Disorder of mineral metabolism, NOS
• Weight loss, abnormal
• Electrolyte disorder, NOS

Candidate Combined ICD10 codes

Log

• 2025-02-27 (item 4) - Changed from Ca++ > 3.5 OR any Ca++ > 2.55 AND in the presence of signs or symptoms believed to be due to hypercalcemia OR any Ca++ > 2.55 with active treatment for hypercalcemia
• 2024-03-04 - SH/DSM sent out a memo that serum corrected calcium will no longer be reported. Instead if there is a concern for hyper/hypocalcemia an ionized calcium is now recommended.
• 2018-02-12 (item 2) - decided to use thresholds as before ICD10
