Advanced Beneficiary Notice Code

Code system of concepts specifying the status of the patient's or the patient's representative's consent for responsibility to pay for potentially uninsured services. This element was introduced to satisfy CMS Medical Necessity requirements for outpatient services in the United States. Includes concepts such as (a) whether the associated diagnosis codes for the service are subject to medical necessity procedures, (b) whether, for this type of service, the patient has been informed that they may be responsible for payment for the service, and (c) whether the patient agrees to be billed for this service.
