In simple words: This code covers a special liquid food given through a feeding tube to children with inherited metabolic problems. This food has all the nutrients a child needs to grow and is tailored to their specific metabolic condition.It provides 100 calories per unit.

HCPCS code B4162 represents a nutritionally complete enteral formula designed to meet the unique metabolic needs of pediatric patients diagnosed with inherited diseases of metabolism.The formula contains proteins, fats, carbohydrates, vitamins, and minerals, and may include fiber. It is administered via an enteral feeding tube into the stomach or small intestine.The formula is intended to provide 100 calories per unit.

Example 1: A 5-year-old diagnosed with phenylketonuria (PKU) requires a specialized formula to manage their phenylalanine intake.B4162 is used to report the provision of this specialized formula through a feeding tube., A 2-year-old with galactosemia needs a formula free of galactose. B4162 is reported for the administration of the specialized, galactose-free formula via feeding tube., A 10-year-old with maple syrup urine disease (MSUD) needs a formula with restricted branched-chain amino acids. This specialized formula is administered via a feeding tube, and B4162 is the appropriate code.

* Diagnosis of inherited metabolic disease* Documentation of the patient's specific metabolic needs and why a standard formula is inadequate* Type and quantity of formula administered* Route of administration (enteral feeding tube)* Frequency of administration* Any adverse reactions or intolerances

** Medicare coverage requires documentation of medical necessity.The formula's caloric density (100 calories per unit) is a key component of the code.
