Clinical Context
A 58-year-old patient with advanced oropharyngeal cancer and progressive dysphagia is admitted for ongoing nutrition support following partial glossectomy and radiation therapy. Oral intake is insufficient to meet caloric and micronutrient needs. A percutaneous endoscopic gastrostomy (PEG) tube is placed earlier in the hospital stay. The patient receives commercially prepared blenderized enteral formula through the PEG tube for home infusion. The formula is a manufactured blenderized natural foods product that provides intact proteins, fats, carbohydrates, vitamins, minerals, and may include fiber. Dosing is billed in units of 100 calories per unit using B4149.
Clinical workflow:
-
Initial nutritional assessment by registered dietitian and ordering clinician to determine caloric needs and suitability of blenderized enteral formula.
-
Enteral access confirmation (PEG/NG/jejunal) by procedural team; documentation of feeding route and tube type in procedural note.
-
Prescription of B4149 with total daily caloric requirement converted to units (100 calories = 1 unit) on durable medical equipment (DME) order for home enteral nutrition.
-
Coordination with pharmacy or enteral nutrition vendor for product selection, patient education on tube feeding administration, storage, and handling.
-
Nursing or home health visit for training on administration, troubleshooting, and monitoring for intolerance or tube complications.
-
Follow-up outpatient nutrition and wound/oncology visits to reassess needs and modify formula or feeding regimen as clinically indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|
11 | Professional component | When reporting the professional component of a service distinct from a technical component associated with enteral nutrition (rare for DME supplies). |
22 | Increased procedural services | When work or resources are substantially greater than typically required for processes related to enteral feeding management (documentation required).
26 | Professional component | When a clinician bills separately for a professional service related to enteral nutrition supply (e.g., nutrition counseling when separately billable).
52 | Reduced services | When fewer supplies or lower volume than ordered are delivered or when service scope is reduced.
53 | Discontinued procedure | When an ordered enteral feeding delivery or related procedure is started but terminated for patient safety reasons.
54 | Surgical care only | When a surgical team provides only the operative portion related to gastrostomy tube placement; supply billing for B4149 is separate.
55 | Postoperative management only | When another provider bills for post-op care while initial surgeon bills procedure; impacts procedural attribution, not B4149 directly.
62 | Two surgeons | When shared surgical responsibility applies for procedures (relevant only if enteral access was established surgically).
78 | Unplanned return to the operating/procedure room | When complications require unexpected return to the OR related to enteral access.
80 | Assistant surgeon | When an assistant surgeon is billed during placement of enteral access.
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for Medicare-certified ASC | When advanced practice clinician provides services in the ambulatory surgery center relevant to enteral access placement.
KX | Requirements specified in the medical policy have been met | When documentation supports medical necessity criteria for coverage of enteral formula per payer policy.
NU | New equipment | When supplying enteral-related durable medical equipment that is new to the patient alongside formula supply.
RR | Rental (purchase under rental) | When associated DME is billed as a rental; may accompany formula supply orders in vendor billing.
| Taxonomy Code | Specialty | Notes |
|---|
2080P0206X | Gastroenterology | Manages enteral access creation (e.g., PEG placement) and GI-related feeding intolerance. |
207L00000X | Nutritionist/Dietitian | Performs nutritional assessment, selects appropriate blenderized enteral formulas, and documents caloric orders.
207Q00000X | Physician Assistant | Provides clinician services related to feeding tube care and follow-up in outpatient or home health settings.
207R00000X | Registered Nurse | Provides education, tube-feeding administration training, and home health visits for enteral nutrition support.
2085R0201X | General Surgery | Performs surgical placement of enteral access when PEG or surgical gastrostomy is required.
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|
E46 | Unspecified protein-calorie malnutrition | Indicates need for concentrated enteral nutrition such as B4149 to restore caloric and protein intake. |
