Diagnostic imaging
About 70490: Neck soft-tissue CT without contrast
CT of the neck’s soft tissues without contrast, reported when the diagnostic question calls for cross-sectional imaging without contrast material.
This study uses computed tomography to produce cross-sectional images of the neck’s soft tissues without contrast material. Radiologists interpret examinations performed in hospital imaging departments, outpatient centers, and other diagnostic imaging settings. Clinical questions may involve a neck mass, cervical lymph nodes, or other soft-tissue findings; the ordering clinician selects the protocol based on the diagnostic question and the patient’s circumstances.
Report 70490 when the examination covers the soft tissues of the neck and is performed without contrast. The order and imaging report should support the anatomic area examined and the noncontrast technique. Use 70491 for a neck soft-tissue CT with contrast, or 70492 when both without- and with-contrast imaging is performed. CMS recognizes separately priced professional and technical components: modifier 26 identifies the interpretation, modifier TC the equipment and staff, and no modifier represents the global service. When multiple diagnostic imaging procedures are reported, the imaging multiple-procedure reduction applies to both the professional and technical components.
