What 77054 covers
This diagnostic breast study uses radiographic imaging to show mammary ducts after contrast is introduced through a nipple duct. It is most often performed by a radiologist in an imaging department when a patient has concerning nipple discharge and duct imaging is part of the evaluation. The images can help locate an abnormality within the ductal system for clinical assessment.
Report the code when the documented service is mammary duct X-ray imaging, rather than routine breast imaging alone. The record should support the clinical indication and the duct imaging performed, including the interpreting physician’s findings. CMS recognizes separately priced professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or no component modifier when billing the global service. The professional and technical services may be billed by different entities when each performs its respective portion.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

77054 billing questions
When is ductography reported instead of diagnostic mammography?
Use this code for imaging of mammary ducts after contrast is introduced into a duct. Diagnostic mammography images breast tissue and is not a substitute for duct imaging.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
What documentation supports this service?
Document the clinical reason for duct imaging, the duct study performed, and the radiologist’s interpretation. Abnormal nipple discharge is a common reason for this examination.
Is this code for a routine mammogram?
No. It describes radiographic imaging of mammary ducts, not standard screening or diagnostic mammography.
How should this code be distinguished from 77053?
Both codes concern mammary duct X-ray imaging. Check the full current CPT descriptors and the documented study details to select the applicable code.
