What 76604 covers
This service uses real-time ultrasound to evaluate chest structures, with saved images supporting the examination and interpretation. Common clinical questions include whether pleural fluid is present and the appearance of the pleural space; the examination can also assess chest-wall or mediastinal structures. Radiologists, pulmonologists, emergency physicians, and other qualified practitioners may perform or interpret it in office, hospital, or emergency settings.
Report 76604 when the documented service is a diagnostic chest ultrasound, rather than breast imaging or ultrasound used only to guide a procedure. The record should identify the clinical question, area examined, images obtained, and findings or interpretation. A physician may report the professional component with modifier 26, the equipment and staff portion with modifier TC, or the global service without either modifier. CMS applies the diagnostic imaging multiple-procedure reduction to both the technical and professional components when applicable.

- 76642Breast ultrasound

- 76942Ultrasound needle guidance

76604 billing questions
When should 76604 be used instead of 76641 or 76642?
Use 76604 for diagnostic ultrasound of thoracic structures such as the pleural space, chest wall, or mediastinum. Codes 76641 and 76642 describe breast ultrasound, with the choice depending on the extent of the breast examination.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the physician's interpretation and modifier TC for the equipment and staff portion; billing without either modifier represents the global service.
Can 76604 be reported with thoracentesis?
It may be reported when a distinct diagnostic chest examination is performed and documented. Do not treat imaging that is integral to the thoracentesis as a separate diagnostic examination.
What documentation supports 76604?
Document the reason for the study, the thoracic area evaluated, saved images, and the findings or interpretation. The record should make clear that the service was diagnostic rather than solely procedural guidance.
How does the multiple-procedure reduction affect this code?
CMS applies the diagnostic imaging multiple-procedure reduction to the technical and professional components when applicable. The reduction can therefore affect either separately billed component.
