Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
