What 76641 covers
A complete breast ultrasound evaluates all four quadrants and the retroareolar region of the breast; the axilla is included when examined. It is commonly used to assess a palpable lump, focal pain, or a finding seen on mammography. A sonographer may acquire the images, while a radiologist or other qualified physician interprets them and documents the findings in an imaging report. The examination may be performed in a hospital imaging department or an outpatient imaging center.
Select this code when the documented study is complete rather than limited to one or more specific areas. Report it for each breast examined; for a bilateral study, use modifier 50, which CMS pays at 150%. The service may be billed globally, or split into the professional interpretation with modifier 26 and the technical portion with modifier TC. The report and image documentation should support the examination's extent and the interpretation.
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.

76641 billing questions
When should 76641 be selected instead of 76642?
Use 76641 when the examination covers all four quadrants and the retroareolar region. A study limited to one or more areas, but not the complete breast, is reported with 76642.
How is a bilateral complete breast ultrasound reported?
Report the bilateral service with modifier 50. CMS pays the bilateral procedure at 150%.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical portion. Without either modifier, the claim represents the global service.
What documentation supports a complete examination?
The imaging report should identify the breast examined, document evaluation of all four quadrants and the retroareolar region, and include the findings and interpretation. Document axillary evaluation when performed.
Can diagnostic mammography be reported on the same date?
Diagnostic mammography may be performed during the same encounter when clinically indicated, such as evaluation of a breast symptom or imaging finding. The mammography report should document that separate examination.
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.
