G0279 - 3D mammography imaging (breast tomosynthesis)
Healthcare Common Procedure Coding System
What is a HCPCS Code?
HCPCS (Healthcare Common Procedure Coding System) codes are used to identify medical procedures, supplies, and services for billing purposes. These codes help standardize how healthcare services are reported and billed across different providers and insurance companies.
Detailed Description
This code represents diagnostic digital breast tomosynthesis, which is a specialized type of 3D mammography. It creates detailed, layered images of breast tissue that can be viewed slice by slice, similar to a CT scan but specifically for breast imaging. This procedure can be performed on one breast (unilateral) or both breasts (bilateral) and is used in addition to standard mammography to get clearer, more detailed images of breast tissue. The 3D imaging helps radiologists see through overlapping tissue layers that might obscure abnormalities in traditional 2D mammograms.
Additional Information
This is an add-on code that must be billed with a primary mammography code. The tomosynthesis provides enhanced imaging that can reduce the need for follow-up imaging due to overlapping tissue. This technology is particularly helpful for patients with dense breast tissue.
