What 76642 covers

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.

How to choose

76641Breast ultrasound
76641 requires documentation of all four quadrants plus the retroareolar region; any targeted or partial exam of the breast is 76642.
76604Chest ultrasound
76604 images the chest wall or mediastinum, not breast parenchyma. Breast lumps and mammographic findings are reported with breast ultrasound codes.
19083Breast biopsy
19083 is a breast biopsy with ultrasound guidance included; 76642 describes a diagnostic breast exam and is not billed solely for imaging used to guide the biopsy needle.

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 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.
