Abn findings on neonatal screen for inborn errors of metab

This code signifies an abnormal result detected during routine neonatal screening for various inborn errors of metabolism. These are genetic conditions where the body cannot properly convert food into energy, leading to a buildup of toxic substances or a deficiency of essential ones. Examples include phenylketonuria (PKU), congenital hypothyroidism, and galactosemia.

Assign this code when a newborn's initial metabolic screening test yields a positive or abnormal result, indicating a potential inborn error of metabolism. This code is typically used before a definitive diagnosis is established through confirmatory testing. Documentation should clearly state "abnormal neonatal metabolic screen" or similar findings.

• Do not use this code once a definitive diagnosis for a specific inborn error of metabolism has been confirmed; instead, code the specific condition.
• This code is for the finding of an abnormal screen, not the performance of the screening test itself.
• Consider sequencing this code as a primary diagnosis when the abnormal screen is the reason for the encounter, followed by codes for any associated signs or symptoms.
