Hypochloremia of newborn

This code signifies an abnormally low level of chloride in the blood of a newborn. This electrolyte imbalance can lead to various metabolic disturbances and impact fluid balance in the neonate. It is often associated with conditions causing excessive chloride loss or inadequate intake.

Apply this code when documentation confirms a diagnosis of hypochloremia specifically in a newborn patient. This typically requires laboratory confirmation of low serum chloride levels in conjunction with clinical signs or symptoms. Supporting documentation should include lab results and physician's assessment.

• Ensure the documentation explicitly states "newborn" or "neonate" in relation to the hypochloremia.
• Investigate the underlying cause of the hypochloremia; code the primary condition first if known and applicable.
• Do not confuse with general hypochloremia (E87.8) which is for patients beyond the neonatal period.
