Summary & Overview
HCPCS Level II E0780: Ambulatory Infusion Pump, Mechanical, Reusable
HCPCS Level II code E0780 identifies a mechanical, reusable ambulatory infusion pump intended for infusions lasting less than eight hours. This DME code matters nationally because it designates coverage and billing for short-duration infusion devices used in outpatient, home health, and ambulatory infusion center settings—settings that continue to expand as care shifts away from inpatient facilities.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how the code is defined, the clinical contexts where short-duration ambulatory pumps are used, and typical sites of service. The publication summarizes payer coverage patterns, common billing modifiers, and related billing considerations relevant to durable medical equipment and infusion therapy.
The content provides benchmarks for utilization and reimbursement where available, highlights recent policy updates affecting DME infusion pumps, and outlines claims submission elements to consider when billing HCPCS Level II code E0780. The goal is to give billing managers, compliance officers, and policy analysts a concise national perspective on the code’s clinical role and billing implications.
Billing Code Overview
HCPCS Level II code E0780 describes an ambulatory infusion pump, mechanical, reusable, for infusion less than 8 hours. This device is used to deliver controlled doses of medication over short infusion periods and is intended for ambulatory use outside of an inpatient setting.
Service type: Durable medical equipment — ambulatory infusion pump
Typical site of service: Outpatient clinic, ambulatory infusion center, home health setting where short-duration infusions are administered

Clinical & Coding Specifications
Clinical Context
A patient with a need for short-duration ambulatory infusion is discharged from the hospital after an orthopedic procedure with intractable postoperative nausea and vomiting and requires outpatient antiemetic therapy delivered by continuous infusion for up to 8 hours. The clinician prescribes an ambulatory mechanical infusion pump for home use to deliver ondansetron or a low-rate opioid-sparing analgesic infusion. The durable medical equipment supplier (DME) provides a reusable mechanical pump coded as E0780, trains the patient and caregiver on pump operation, troubleshooting, reservoir loading, and safe transport, and documents pump settings, infusion duration, and patient tolerance. The DME coordinates delivery to the patient’s residence or outpatient infusion center and documents verification of physician order, delivery date/time, and patient instruction.
A typical workflow: clinician documents indication and orders the pump; DME verifies eligibility and payer coverage, prepares pump and supplies, provides in-person training, delivers device to the site of service (home or ambulatory infusion center), and documents delivery and patient education. Follow-up contact occurs within 24–48 hours to confirm device function and patient tolerance; pump is returned to DME for reuse after completion of therapy.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier | Use when no special circumstances apply and standard billing is submitted |
22 | Increased procedural services | Use when unusually high resource use for delivery or training is documented and payer allows modifier for DME-related services |
23 | Unusual anesthesia | Not typically used for E0780; included for completeness when anesthesia influences related services |
52 | Reduced services | Use when pump is provided with reduced functionality or shorter duration than ordered |
53 | Discontinued procedure | Use if pump delivery or initiation is stopped prior to planned start due to clinical reasons |
62 | Two surgeons | Rare for DME; use only if two providers share responsibility for related procedural care that affects billing coordination |
78 | Return to operating/procedure room for a related procedure by same physician | Use if patient requires an immediate return to ambulatory infusion suite for device-related corrective procedure |
80 | Assistant surgeon | Use if an assistant surgeon is involved in a related procedural service that impacts billing coordination |
82 | Assistant surgeon (when qualified resident not available) | Similar to 80 when a qualified resident is not available |
TC | Technical component | Use when billing only the technical component of a related service (e.g., supplies or pump technical rental) and professional services billed separately |
26 | Professional component | Use when billing only the professional component (e.g., clinician oversight of infusion therapy) separate from the pump supply |
QK | Medical direction of two or three assistants | Use only if clinical staffing for related procedures meets criteria and influences accompanying services |
QX | Modifier X: CRNA service with medical direction by anesthesiologist | Rare for ambulatory pump but used when CRNA care accompanies infusion-related procedures |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
334900000X | Physical Therapist | DME vendors and physical therapists may coordinate mobility and safety training when pumps are used in home care |
333600000X | Home Health Agency | Agencies manage home infusion services, training, and device oversight |
207Q00000X | Anesthesiology | Anesthesiologists prescribe infusion regimens for postoperative pain or antiemetic infusions in perioperative care |
207L00000X | Pain Medicine | Pain specialists order ambulatory pumps for short-term analgesic infusions |
