Hypocalcemia

This code represents a condition characterized by abnormally low levels of calcium in the blood. Hypocalcemia can manifest with various symptoms, including muscle cramps, paresthesias, and in severe cases, seizures or cardiac arrhythmias. It often indicates an underlying metabolic or endocrine disorder.

Assign this code when documentation explicitly states a diagnosis of hypocalcemia. This includes cases identified through laboratory findings (serum calcium levels below the normal range) and/or clinical signs and symptoms attributable to low calcium. It is appropriate for both acute and chronic presentations.

• Always confirm the diagnosis with laboratory results or a physician's definitive statement.
• Investigate for an underlying cause (e.g., parathyroid disorder, vitamin D deficiency) and code it as a primary diagnosis if known and clinically relevant.
• Do not use this code for transient or expected calcium fluctuations post-surgery unless specifically diagnosed as hypocalcemia.
