HCPCS Code B4087: Gastrostomy/jejunostomy tube billing guide

Key Takeaways

HCPCS Code B4087 describes a gastrostomy or jejunostomy tube, standard, any material, any type, each – billed under the Medicare Part B DME benefit.

A valid physician order and certificate of medical necessity (CMN) must be on file before submitting a B4087 claim; missing CMN is the leading denial reason.

B4087 covers the standard (conventional) tube; use B4088 for low-profile (button-style) devices – selecting the wrong code triggers automatic claim rejection.

Pabau’s claims management software and digital forms help clinics track CMN status, document medical necessity, and submit enteral access device claims accurately.

HCPCS Code B4087 is the billing code for a standard gastrostomy or jejunostomy tube under the CMS HCPCS Level II coding system. It sits within the Enteral and Parenteral Therapy supply category (B4000-B9999) and is processed by the Durable Medical Equipment Medicare Administrative Contractors (DME MACs).

The code’s official long description is: Gastrostomy/jejunostomy tube, standard, any material, any type, each. The phrase “any material, any type” is intentional. CMS designed HCPCS Code B4087 to be device-agnostic, covering silicone, polyurethane, and PVC tubes regardless of brand or construction, so billers do not need separate codes for each manufacturer’s variation.

B4087 code description and key details

The table below summarises the administrative attributes of HCPCS Code B4087 as defined in the current CMS HCPCS Level II data file.

Note the “each” unit of service at the end of the long description. Submit one unit per tube supplied, not per patient encounter. Submitting multiple units without corresponding documentation for each device is a common audit trigger.

2026 Medicare fee schedule for HCPCS Code B4087

Reimbursement for HCPCS Code B4087 is set annually through the CMS DMEPOS (Durable Medical Equipment, Prosthetics, Orthotics and Supplies) fee schedule. Rates vary by MAC jurisdiction. The figures below reflect published 2026 national averages; always verify current rates against the official CMS HCPCS code list for your jurisdiction before billing.

Because exact fee amounts change with each annual DMEPOS update, this guide does not publish specific dollar figures. Commercial sources list rates, but only the official CMS HCPCS data file is authoritative. Pull the current DMEPOS fee schedule directly from CMS before billing B4087 for the first time each calendar year.

Medicare coverage criteria for B4087

Medicare Part B covers HCPCS Code B4087 under the DME benefit when the patient has a permanent or long-term condition requiring enteral feeding and the tube is medically necessary. Providers handling enteral access device billing should also review HIPAA compliance requirements for primary care billing to ensure documentation handling meets federal standards.

Coverage applies when all of the following criteria are met:

• The patient has a permanent impairment of the alimentary tract that prevents adequate oral nutrition
• The patient requires enteral nutrition via a gastrostomy or jejunostomy tube as the primary means of sustenance
• The treating physician has documented medical necessity in a written order and a completed CMN
• The tube is supplied by a Medicare-enrolled DMEPOS supplier
• The patient is a Medicare Part B beneficiary who does not reside in a skilled nursing facility (SNF) at the time of supply

Medicare does not cover temporary post-surgical tubes expected to be removed within a few weeks. The benefit is designed for chronic conditions requiring long-term enteral access. Always verify Local Coverage Determination (LCD) policies with your specific DME MAC, as coverage criteria can include additional clinical documentation requirements.

Documentation requirements and medical necessity

Missing documentation is the primary reason B4087 claims get denied. Good management of medical forms at your practice is not optional for DME billing; it is the compliance foundation that keeps claims out of the denial queue.

Every B4087 claim requires the following on file before submission:

• Physician order: A written order from the treating physician specifying the type and quantity of the enteral access device. The order must pre-date the supply date.
• Certificate of Medical Necessity (CMN): The applicable CMS CMN form completed by the ordering physician. The CMN must document the clinical condition, the specific device ordered, and the expected duration of need.
• Clinical notes: Supporting documentation showing the patient’s diagnosis, weight, nutritional assessment, and the clinical rationale for a tube-based feeding route.
• Supplier enrollment confirmation: Evidence that the DMEPOS supplier is enrolled and in good standing with Medicare at the time of supply.

Practices using digital forms can standardise CMN collection and physician order workflows, reducing the risk of missing or unsigned documents at the time of claim submission. For broader guidance on secure patient documentation practices, keeping records audit-ready is especially important for DME suppliers subject to Medicare post-payment review.

ICD-10 diagnosis codes that support medical necessity

Pairing HCPCS Code B4087 with an appropriate ICD-10-CM diagnosis code is required to establish medical necessity on the claim. The diagnosis must reflect the underlying condition that necessitates the gastrostomy or jejunostomy tube. For a broader look at related ICD-10 diagnostic coding in clinical contexts, the coding logic follows the same medical necessity principle across specialties.

Always cross-reference this list against your DME MAC’s current LCD. Some MACs publish expanded ICD-10 supporting diagnosis lists, and diagnosis codes must be active and valid for the date of service. Verify codes against the CDC ICD-10-CM tool before claim submission.

B4087 vs B4088: Standard vs low-profile tubes

B4087 and B4088 cover two clinically distinct product types. Selecting the wrong code is one of the most common B-range billing errors because the devices look similar in supplier catalogues. The distinction is based on the tube’s physical profile, not the insertion site.

The physician order and supplier delivery documentation must specify the tube type. If the order says “standard G-tube” but the supplier ships a button-style device and bills B4087, that mismatch constitutes incorrect coding. Train intake staff to confirm device specifications against the HCPCS description before the order is fulfilled.

Related HCPCS codes in the B4081-B4088 range

HCPCS Code B4087 sits within a family of gastrostomy and jejunostomy tube codes. Billers working with enteral access devices should be familiar with the full range for accurate code selection. See also the procedure code billing reference for how code families work across supply categories.

Note that B4084 and B4087 can appear to overlap. B4084 is specific to tubes of 12 French gauge or larger and is not low-profile. Check device specifications against the AAPC’s HCPCS Level II code lookup when in doubt.

Common billing errors and how to avoid them

DME enteral tube billing attracts a higher rate of post-payment review than many other HCPCS categories. Understanding the most common errors before they reach the payer is far less costly than resolving a recoupment request after the fact. Practices can learn from patient data security tools that audit documentation gaps the same way billing teams should audit claim documentation before submission.

• Missing or expired CMN: The single most common denial reason. The CMN must be current, signed by the ordering physician, and on file before the claim is submitted. CMNs for enteral nutrition equipment have a defined duration; bill suppliers must track renewal dates.
• B4087 vs B4088 mismatch: Billing B4087 (standard) when the device supplied is a low-profile button (B4088) is an incorrect code selection. Verify device type against the physician order and delivery records.
• Incorrect ICD-10 pairing: Using a diagnosis code that does not appear on the MAC’s LCD supporting diagnosis list will result in denial. Confirm your ICD-10-CM code is on the current approved list for B4087.
• Wrong unit count: B4087 is billed per each tube. Submitting a unit count higher than the number of devices actually supplied without documentation creates an overpayment risk.
• Non-enrolled supplier: Claims submitted by a DMEPOS supplier that is not actively enrolled in Medicare will be denied regardless of clinical necessity. Verify enrollment status before accepting an order.

How Pabau supports enteral nutrition DME billing

Enteral access device billing fails most often because of documentation gaps, not clinical ones. A CMN that expires unnoticed, a physician order that was never attached to the patient record, a diagnosis code that is one digit off: these are workflow problems, not coding knowledge problems. The claims management software inside Pabau helps billing teams catch these issues before a claim is submitted.

Pabau’s client records centralise physician orders, CMN forms, and clinical notes in one place, so billing staff can verify documentation completeness without hunting across multiple systems. Teams that have moved toward going paperless in a compliant practice report fewer documentation-related denials because every form is timestamped, searchable, and linked directly to the patient record.

For practices managing automated billing workflows, Pabau can flag approaching CMN renewal dates and prompt the billing team to collect updated documentation before the current CMN expires. Combining EHR integration for clinical workflows with structured claim submission reduces the back-and-forth that delays reimbursement on B-range enteral codes.

Conclusion

Most B4087 claim denials trace back to one preventable gap: missing or expired CMN documentation. Getting the code right is the easy part. The harder discipline is ensuring that every physician order, CMN, and ICD-10 diagnosis is accurate, current, and attached to the claim before it goes out the door.

Pabau’s claims management tools and automated document workflows help DME billing teams close those gaps systematically, so B4087 claims get paid on first submission. To see how Pabau handles enteral nutrition billing documentation, book a demo with the team.
