Unspecified disorder of calcium metabolism

This code signifies a metabolic disturbance involving calcium where the specific type or cause of the imbalance is not documented. It indicates an abnormality in the body's regulation of calcium levels, which can affect various physiological processes.

Use this code when laboratory findings indicate abnormal serum calcium levels (hypercalcemia or hypocalcemia), but the physician's documentation does not specify the underlying etiology or a more precise diagnosis. It is appropriate when the provider has not yet determined if the disorder is due to parathyroid issues, renal dysfunction, vitamin D deficiency, or other specific causes.

• Avoid using this code if a more specific calcium metabolism disorder (e.g., hyperparathyroidism, hypocalcemia due to vitamin D deficiency) is documented.
• Query the provider for further specificity if possible, as this code represents an unspecified condition.
• This code should be sequenced as a secondary diagnosis if the primary reason for the encounter is related to a symptom caused by the calcium imbalance.
