Common Current Procedural Terminology Codes in Breast Imaging

This article reviews the common Current Procedural Terminology (CPT) codes for frequently performed breast imaging procedures. The CPT codes for breast radiology services, including the revised codes for mammography, computer-assisted detection (CAD), breast ultrasound, breast magnetic resonance imaging (MRI), and imaging-guided breast interventional procedures and the new codes for digital breast tomosynthesis (DBT) and marker placement in axillary lymph nodes are outlined. The application of basic CPT coding principles, such as the use of modifiers and the different structure of code families in breast radiology services, is also discussed. CPT codes are updated on an ongoing basis to reflect the evolution of medical practice, and the CPT codes for breast imaging procedures have changed significantly in the past 5 years. These modifications can affect the distribution of work and utilization of resources in radiology departments. A working knowledge of coding practices will facilitate compliance with billing regulations and help ensure breast radiologists are appropriately paid for their work.
