In simple words: This code covers one liter of intravenous nutrition given at home each day. It includes the supplies, pharmacy services, and administration of the nutrition. It's used when someone can't get nutrition through their digestive system.

This code refers to the home infusion of total parenteral nutrition formula on a per day basis. It includes administrative and pharmacy services, along with all necessary equipment and supplies, within the patient’s home, on a per day basis.A skilled provider performs the insertion of intravenous equipment and also administers one liter of a standard total parenteral nutrition formula in a day, one that contains a concentration of all the important nutrients including amino acids, sugar, and fat, which are vital to sustain life processes.

Example 1: A patient with Crohn's disease experiencing severe flare-ups and unable to tolerate oral or enteral nutrition receives one liter of TPN daily at home., A patient with short bowel syndrome requires long-term home TPN due to malabsorption. They receive one liter of TPN solution per day., A patient undergoing chemotherapy experiences severe nausea and vomiting, making oral intake impossible.They receive home TPN, one liter per day, to maintain their nutritional status.

Documentation should include the medical necessity for home TPN, including the patient's diagnosis, inability to tolerate other forms of nutrition, the type and amount of TPN solution administered, the frequency of administration (daily in this case), and any complications or adverse reactions.

** This code does not include provider visits or other drugs which are billed separately. As an S-code, it's crucial to verify coverage with the specific payer, as these codes are not universally recognized.
