In simple words: This code covers a special nutritional fluid given through a vein when a person can't eat normally. It contains a specific amount of protein building blocks (amino acids) and is mixed at home by the patient. It is provided in 500mL units.

This code represents a homemix parenteral nutrition solution containing 7% to 8.5% amino acids, supplied in units of 500 mL. It is administered parenterally (intravenously). The patient mixes the ingredients at home.

Example 1: A patient with Crohn's disease experiencing severe bowel inflammation requires bowel rest and is prescribed homemix parenteral nutrition with 7.5% amino acids (B4176) to maintain adequate nutrition while their digestive system heals. The patient receives daily 500ml units., A patient with short bowel syndrome undergoes surgery and subsequently cannot absorb nutrients through their digestive system. They are prescribed a homemix parenteral nutrition solution with 8% amino acids (B4176) to provide necessary nutrients, delivered intravenously in 500ml units., A patient with a severe gastrointestinal infection is unable to tolerate oral or enteral feeding. To ensure adequate nutritional intake while fighting the infection, they receive B4176, a homemix parenteral nutrition solution with 7% amino acids, in 500ml doses delivered intravenously.

Documentation should support the medical necessity of parenteral nutrition. This includes the patient's diagnosis, the reason for the inability to take nutrition orally or enterally, the specific nutritional requirements of the patient, and the composition of the parenteral solution, including the percentage of amino acids.
