Edit ICD10 dx: Hypocalcemia

{{ICD10 transition status | OldDxArticle = Hypocalcemia Ca Less Than 1.8| CurrentStatus = reconciled | InitialEditorAssigned = Joanna Velasco }} == Additional Info == === Thresholds for pts with regular albumin levels === *The criteria for coding this is are either: **Ca++ <= 1.8 -- but as below, this is only reliable for those with albumin >= 3.0 **ionized Ca++ <=0.8 === Thresholds for pts with hypoalbuminemia === *For patients with substantial hypoalbuminemia using total calcium to define hypocalcemia is a problem. * It's actually the ionized serum calcium that's relevant and causes symptoms when high or low -- AND the usual range for total calcium is altered (downwards) in patients with low serum albumin. So you can have a completely normal ionized calcium with a very low total calcium if the albumin is significantly low. Furthermore, the old "correction" of total calcium for measured albumin does not work well. Thus, to identify truly low circulating calcium in the presence of more than trivial hypoalbuminemia, it's necessary to use measurement of ionized calcium, using the threshold (as above) of ionized Ca++ <=0.8 *Presence/absence of signs or symptoms are not part of the coding criterion, though they are: **GI - nausea\vomiting, abdominal pain **Neuromuscular - paresthesias (esp. acral, perioral), muscle cramps\spasms, hyperreflexia, tetany, weakness, fatigue, seizures, extrapyramidal movement disorders, abnormal EEG **cardiovascular - long QT interval, hypotension (if acute), arrythmias **Miscellaneous - secondary hypoparathyroidism {{ICD10 Guideline Electrolytes}} {{ICD10 Guideline repeated events}} == Alternate ICD10s to consider coding instead or in addition == *[[Tetany]] *[[Disorder of mineral metabolism, NOS]] *[[Electrolyte disorder, NOS]] *[[Hyperparathyroidism]] *[[Parathyroid disorder, NOS]] *[[Cushing's syndrome, NOS]] *[[Vitamin D deficiency]] == Candidate [[Combined ICD10 codes]] == == Related CCI Codes == {{Data Integrity Check List}} == Related Articles == {{Related Articles}} {{ICD10 footer}} {{EndPlaceHolder}}
