2025 HCPCS code B4102

Enteral formula for adults, used to replace fluids and electrolytes.

One unit of B4102 represents 500 ml of enteral formula. Modifier BO may be appended to indicate orally administered nutrition (if applicable).Prior authorization may be required by some payers.

Modifiers may be applicable to further specify the circumstances of administration.

Medical necessity must be established by demonstrating the patient's inability to maintain adequate hydration and electrolyte balance through oral intake, as in cases of dysphagia, bowel obstruction, or severe nausea and vomiting.

This code is used by healthcare providers administering enteral nutrition to adult patients who cannot maintain adequate hydration and electrolyte balance through oral intake.It involves inserting a feeding tube and monitoring the patient's tolerance and response to the formula.

In simple words: This is a special liquid food for adults that is given through a feeding tube. It's used when someone can't drink enough regular fluids or is losing important body salts.

Enteral formula, for adults, used to replace fluids and electrolytes (e.g., clear liquids), 500 ml = 1 unit.

Example 1: A patient with dysphagia following a stroke requires enteral feeding to maintain hydration and electrolyte levels. B4102 is used for the prescribed formula., A patient with a bowel obstruction requires fluid and electrolyte replacement. B4102 can be used to supply the necessary nutrients., An adult patient undergoing chemotherapy experiences severe nausea and vomiting, making it difficult to maintain adequate fluid and electrolyte intake orally. B4102 is used to administer enteral formula.

Documentation should include the medical necessity for enteral nutrition, type and amount of formula administered, patient tolerance, and any complications.
