Radiology
About 76642: Limited unilateral breast ultrasound
Real-time ultrasound of one breast targeted to a specific area or finding, such as a palpable lump or mammographic abnormality, with image documentation and axilla when scanned.
A limited breast ultrasound evaluates one breast with real-time scanning focused on a defined region rather than the entire breast. Typical indications include a palpable lump, focal pain, nipple discharge, a mass or asymmetry seen on diagnostic mammography, or short-interval follow-up of a known probably benign lesion. The axilla is included when it is scanned. A sonographer or radiologist performs the exam in an imaging center, hospital outpatient department, or breast surgeon's office, and a radiologist or breast surgeon interprets it with permanent images and a written report.
Choose this code when the exam does not cover all four quadrants plus the retroareolar region; full surveys go to the complete code. The report should state the side, the targeted area or clock-face location, findings, and an impression. The code is unilateral, so scanning both breasts is reported with modifier 50, which CMS pays at 150%. It splits into a professional component (modifier 26) for the interpretation and a technical component (modifier TC) for equipment and staff; reporting without either modifier bills the global service, used when one entity both performs and reads the study.

76642 billing questions
When should 76642 be reported instead of 76641?
Use 76642 when the scan targets a specific area or finding in one breast. Use 76641 only when all four quadrants and the retroareolar region are examined and documented.
How is a limited ultrasound of both breasts billed?
Report 76642 once with modifier 50, which Medicare pays at 150% of the unilateral amount. Do not report two units or two lines without the bilateral modifier for Medicare.
Is axillary scanning billed separately?
No. Evaluation of the axilla is included in this code when performed, so a separate limited ultrasound of the axilla is not added for the same side.
Which modifier does a hospital-based radiologist append?
When the hospital owns the equipment and bills the technical portion, the reading radiologist reports 76642 with modifier 26 for the interpretation only. A freestanding center that performs and reads the exam bills globally without a modifier.
Can 76642 be billed for ultrasound guidance during a breast biopsy?
No. Ultrasound-guided breast biopsy code 19083 includes the imaging guidance, so 76642 is not reported just to guide the biopsy needle.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
