Transitory neonatal disord of calcium & magnesium metab,unsp

This code describes a temporary, unspecific disturbance in a newborn's calcium and/or magnesium levels. These metabolic imbalances are typically transient and resolve without long-term sequelae, often presenting as hypocalcemia or hypomagnesemia.

Use this code for newborns diagnosed with an unspecified, temporary disorder of calcium and/or magnesium metabolism. Documentation should indicate a transient nature and lack of a more specific underlying cause (e.g., maternal diabetes, prematurity, or specific genetic syndromes).

• Only use this code when the specific type of calcium or magnesium disorder (e.g., hypocalcemia, hypercalcemia) is not documented, or when the underlying cause is unknown.
• If a specific cause or type of disorder is identified, a more precise code from the P71 series should be used.
• Always sequence this code as a secondary diagnosis if the primary reason for admission or encounter is related to another condition.
