Transitory metabolic disturbance of newborn, unspecified

This code represents a temporary and undiagnosed metabolic imbalance occurring in a newborn. It signifies a transient disruption in the infant's metabolic processes that resolves without specific intervention or a definitive underlying cause being identified.

Use this code when a newborn exhibits signs of a metabolic disturbance (e.g., hypoglycemia, electrolyte imbalance) that is documented as transient and for which a specific diagnosis (e.g., specific enzyme deficiency, maternal diabetes-induced hypoglycemia) cannot be established. Documentation should clearly state the metabolic issue was temporary and the cause remains unspecified.

• Do not use this code if a specific metabolic disorder or its cause is identified; instead, code the specific condition.
• Consider sequencing this code after any presenting symptoms if the metabolic disturbance is the primary reason for admission or encounter.
• Ensure documentation explicitly states "unspecified" or "transient" and that no definitive underlying cause was found.
