The Global Services Division has welcomed thousands of patients from around the world seeking remote second opinions or medical care in the United States.

Our goal is to deliver a positive experience from the child’s first contact to the time they return home. The Global Services Division features a multilingual team experienced in providing world-class services to international patients and families. Our team is comprised of the following members:

  • Medical director. The Global Services medical director oversees all aspects of medical care for our international patients. The Medical Director works closely with other members of the Global Services team to coordinate care with the primary medical team, referring physicians, and patients and families to ensure the best possible care at Children’s National.
  • Nurse practitioners. Our nurse practitioners are vital members of the international patient care team, serving as your child’s primary care providers. In collaboration with our specialists, a nurse practitioner oversees all aspects of your child’s treatment to provide comprehensive and continuous medical care throughout their treatment, as well as during the transition back to your home country.
  • Nurse navigators. The Global Services nurse navigators are experienced nurses who oversee the coordination of your child’s medical care – decreasing anxiety, increasing your child’s satisfaction and improving communication among members of your child’s care team. A nurse navigator is instrumental in partnering with the patient care coordinators to streamline your child’s care from the hospital setting to your home.
  • Patient care coordinators. The Global Services patient care coordinators are multilingual staff members who work directly with patients and families on all services needed prior to arrival, during treatment and upon discharge. Our coordinators work closely with our clinical team to facilitate all aspects of your child’s care. This includes coordinating hospital admissions, outpatient appointments and procedures, as well as facilitating communication with your child’s sponsor. Patient care coordinators are certified to provide interpretation services for our patients and families. He or she will serve as your personal guide to the hospital and will work closely with you to ensure that your child and family receive the best possible service and care at Children’s National.
  • Medical interpreters. The Global Services medical interpreters provide medical interpretation and translation of complex medical information to patients who speak a foreign language. They ensure the complete understanding of medical information between doctors, nurses, medical staff and patients. They translate a wide range of medical information that includes medical conditions, treatment options, follow-up appointment details, billing and insurance. Our medical interpreters are the communication link between a doctor and patient, and they strive to provide a positive and relaxed experience, so patients feel comfortable disclosing sensitive information about their medical conditions.
  • Finance coordinators. The Global Services financial coordinators are responsible for managing the daily financial operations of the Global Services Division. Their scope starts at the patient registration process through billing and collections, and they regularly prepare financial reports to the department. They are responsible for creating detailed cost estimates, patient registration, direct interaction with foreign payers, international insurances and embassies.

    The Global Services Division offers one main point of contact for international patients to navigate their journey at Children’s National. Our team understands the challenges of traveling abroad for medical care and we work diligently in coordinating all the clinical and logistical aspects of the visit, making sure that each patient’s cultural, linguistic and religious needs are met.
