What G0279 covers
G0279 covers digital breast tomosynthesis (DBT), often called 3D mammography, performed as part of a diagnostic mammogram. The tomosynthesis unit acquires low-dose projections from multiple angles, which are reconstructed into thin slices. A radiologist uses them to evaluate a palpable lump, nipple discharge, a callback from screening, or a finding under short-interval follow-up. Technologists acquire the images in hospital outpatient breast centers and freestanding imaging facilities. A radiologist interprets the slices alongside the mammographic views.
Report G0279 only with diagnostic mammography code 77065 (one breast) or 77066 (both breasts). Document that tomosynthesis was performed and identify the breast or breasts imaged. Report one unit whether tomosynthesis examines one or both breasts: the code is priced as bilateral, so modifier 50 does not increase payment. As an add-on, it is paid within the primary procedure’s global period. Use modifier 26 for interpretation, modifier TC for the equipment and staff portion, or no component modifier when one entity bills the global service.

G0279 billing questions
Can G0279 be reported with a screening mammogram?
No. G0279 accompanies diagnostic mammography with 77065 or 77066. Tomosynthesis added to a screening mammogram (77067) is reported with add-on 77063 instead.
Why bill G0279 to Medicare instead of CPT 77061 or 77062?
Medicare uses G0279 with the diagnostic mammography code rather than paying the CPT diagnostic tomosynthesis codes 77061 and 77062.
How many units are reported if both breasts receive tomosynthesis?
One unit. G0279 covers unilateral or bilateral tomosynthesis and is already priced as bilateral; do not add modifier 50 or a second unit.
How is G0279 split between a hospital and a radiology group?
The radiologist bills G0279-26 for interpretation. The hospital reports its facility service through hospital outpatient billing; an entity billing the technical portion on the physician fee schedule uses G0279-TC. Each bills the applicable portion of 77065 or 77066 as well.
What documentation supports G0279?
The record should show that diagnostic tomosynthesis images were acquired and interpreted, identify the breast or breasts examined, and support the accompanying diagnostic mammogram.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
