    Clinical & Coding Specifications

    Clinical Context

    A typical patient is an adult hospitalized for acute dehydration from viral gastroenteritis, postoperative ileus, or fluid-restricted oral intake who requires enteral replacement of fluids and electrolytes but can tolerate an oral or enteral clear-liquid formula. The order originates from the admitting physician or hospitalist; nursing obtains the enteral formula from pharmacy or central supply and documents administration volumes in the medication administration record. Billing uses B4102 with units calculated per 500 mL; for example, a 1,000 mL supply equals two units. Care team members involved commonly include the ordering physician, bedside nurse, registered dietitian (for electrolyte/volume assessment), and pharmacy for stocking and verification. Documentation should include the indication (e.g., dehydration, short-term oral intake intolerance), volume administered, start and stop dates/times, and any intolerance or adverse reaction notes.
