Common Language Description

The CPT® Code 77051 pertains to the use of computer-aided detection (CAD) in the context of diagnostic mammography. This procedure involves the application of a computer algorithm to analyze digital image data specifically for the purpose of detecting lesions within breast tissue. The process may also include the digitization of film radiographic images, although this is not a mandatory component of the procedure. The primary function of this code is to facilitate the identification of potential abnormalities in mammographic images through advanced technology, which enhances the radiologist's ability to interpret the results accurately. The CAD system works by scanning the mammographic images, often converting analog film into digital format, and then systematically analyzing the data displayed on a monitor. This analysis focuses on identifying unusual or suspicious areas that may require further investigation. It is important to note that this code is considered an add-on code, meaning it should be reported in conjunction with the primary procedure codes for diagnostic mammography (CPT® 77051) or screening mammography (CPT® 77052). This ensures that the additional interpretive review provided by the CAD system is appropriately documented and billed alongside the primary mammographic services rendered.
