Summary & Overview

HCPCS B5000: Compounded Parenteral Nutrition Solution with Amino Acids and Carbohydrates

HCPCS Level II code B5000 covers compounded parenteral nutrition solutions composed of amino acids and carbohydrates with electrolytes, trace elements, and vitamins, including formulations intended for renal patients. This code represents a key supply-line item for hospitals, infusion centers, long-term care facilities, and skilled nursing facilities that provide intravenous nutrition support to medically complex patients. Nationally, parenteral nutrition is a critical component of care for patients with impaired gastrointestinal function or specific metabolic needs; accurate coding ensures appropriate itemization of compounded nutrient solutions and supports claims processing and utilization tracking.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for compounded parenteral nutrition, the typical sites of service where B5000 is billed, and the payer landscape for coverage considerations. The publication also outlines common billing modifiers and related administrative details where available and summarizes benchmarking and policy topics relevant to medical supply and pharmacy billing for parenteral nutrition. Data not available in the input will be identified as such in relevant sections.

Billing Code Overview

HCPCS Level II code B5000 describes a compounded parenteral nutrition solution containing amino acids and carbohydrates with electrolytes, trace elements, and vitamins. The description specifies preparations intended for renal support (examples include renal-aminosyn-rf, nephramine, renamine-premix).

Service type: Parenteral nutrition compounding and administration product provided as a sterile, compounded intravenous nutrition solution.

Typical site of service: Hospital inpatient units, hospital outpatient infusion centers, long-term acute care facilities, and skilled nursing facilities where compounded parenteral nutrition is prepared and administered.

Clinical & Coding Specifications

Clinical Context

A 62-year-old patient with chronic kidney disease stage 4, recent hospitalization for uremic complications, and prolonged inadequate oral intake is admitted for initiation of parenteral nutrition. The clinician prescribes a renal‑specific compounded parenteral nutrition formulation containing amino acids, dextrose (carbohydrates), balanced electrolytes, trace elements, and multivitamins tailored for renal dosing (examples: renal‑aminosyn‑rf, Nephramine, Renamine‑Premix). Pharmacy compounds the premixed solution under sterile technique in the inpatient pharmacy or infusion center. The solution is labeled with patient identifiers, infusion rate, and route (peripheral or central venous catheter). Nursing documents catheter access, infusion start and stop times, daily weights, intake/output, and metabolic lab monitoring (electrolytes, glucose, liver panel, and triglycerides). The interdisciplinary team (nephrology, nutrition support, pharmacy, and nursing) assesses tolerance, adjusts electrolyte composition and calorie/protein goals, and plans transition to enteral or oral nutrition as tolerated. Billing uses HCPCS Level II code B5000 for the compounded parenteral nutrition solution, with appropriate modifier(s) appended to reflect professional or technical components, place of service, or unusual circumstances.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing only the professional component of an associated service (e.g., pharmacist clinical compounding oversight billed separately when allowed).
`TC`	Technical component	Use when billing only the technical component (e.g., pharmacy compounding preparation without professional interpretation).
`59`	Data not provided in the input.	Data not provided in the input.
`52`	Reduced services	Use when the compounded solution or service furnished is partially reduced or not completed as originally planned.
`53`	Discontinued procedure	Use when compounding or infusion is started but discontinued due to extenuating circumstances or patient request.
`22`	Increased procedural services	Use when compounding requires substantially greater resources or complexity than typical (rare; document justification).
`78`	Unplanned return to the operating/procedure room	Use if an infusion‑related procedure requires an unplanned return to procedure space for catheter revision (applies to facility claims as appropriate).
`80`	Assistant surgeon	Use when an assistant surgeon (or comparable clinical role) is billable for a related invasive procedure such as catheter placement.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services	Use when an advanced practitioner performs billable services related to nutrition management per payer policy.
`QK`	Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals	Not typically applicable; include only if anesthesia services are part of catheter insertion and meet criteria.
