What is an ambulatory infusion center?
An ambulatory infusion center (AIC) is an outpatient clinic where patients come in, get an IV or injectable therapy in a treatment chair, and go home the same day. It isn't part of a hospital inpatient unit, and patients aren't admitted. Most give scheduled, repeat treatments such as biologics for autoimmune conditions, immunoglobulin (IVIG), IV iron and IV antibiotics.
What happens at an infusion center
- Scheduled visits: patients book a chair time, often every few weeks for months or years.
- Common therapies: biologics for rheumatology, gastroenterology and neurology patients, IVIG, IV iron, IV antibiotics and hydration. Some centers give oncology treatments too.
- Care around the infusion: vital signs, pre-medications per orders, monitoring for reactions, and teaching patients what to watch for at home.
- Behind the scenes: benefits checks and prior authorizations with insurers, drug ordering and preparation, and coordinating with the referring physician.
This describes how centers operate. It isn't medical advice about any treatment.
Who works there
- Infusion nurses (RNs): start IVs or access ports, run the infusions and handle reactions. See what an infusion nurse does.
- Nurse practitioners or physicians: oversee care, see patients and manage problems. See infusion nurse practitioner.
- Pharmacists and pharmacy technicians: review orders and prepare drugs, on site or through a partner pharmacy. See infusion pharmacist.
- Intake and prior authorization staff: handle referrals, insurance and scheduling.
How it compares with other places to get an infusion
| Setting | What it is |
|---|---|
| Ambulatory infusion center | A standalone outpatient clinic built around infusion chairs. |
| Hospital outpatient infusion | An infusion suite run by a hospital or health system, often with a wider mix of therapies. |
| Physician-office infusion | A rheumatology, GI, neurology or oncology practice that infuses its own patients. |
| Home infusion | A nurse visits the patient at home, usually with a specialty pharmacy supplying the drug. See home infusion vs. infusion centers. |
How many infusion centers are there?
Healthcare organizations register with the federal NPI Registry under a taxonomy code. The code for these clinics is 261QI0500X, listed by NUCC (which maintains the code set) as Ambulatory Health Care Facilities > Clinic/Center > Infusion Therapy. NUCC hasn't published a formal definition for it yet. Our infusion center directory lists 1,847 registered infusion centers under that code, after removing IV-hydration and wellness spas that use the same code. The most are in Florida (242), Texas (242), California (145), Colorado (89), Puerto Rico (78) and Arizona (71).
Not every infusion site registers under this code. Hospital suites and physician offices usually register under their own codes, so the true number of places that infuse is higher.
