BI-RADS 0 is one of seven categories from the breast imaging-reporting and data system and is used when imaging is incomplete such as:

when further imaging or information is required, e.g. compression, magnification, special mammographic views, ultrasound
when requesting previous images not available at the time of reading

In the screening setting, mammograms with suspicious findings should generally be assigned BI-RADS 0 to indicate a callback/recall for diagnostic evaluation.

In the diagnostic setting, a study should be reported as BI-RADS 0 only if there is a need for further information (e.g. focused ultrasound or outside prior exams) that is planned to be obtained at a later time.
