What 19083 covers

Code 19083 describes percutaneous sampling of one breast lesion selected under ultrasound guidance. The clinician advances a biopsy device into the target while observing it with ultrasound; marker placement and imaging of the removed specimen are included when performed. Breast radiologists and other clinicians qualified to perform image-guided breast procedures use it for an ultrasound-visible mass or other target requiring tissue diagnosis, in office-based imaging suites or hospital imaging departments.

Report 19083 for the first lesion sampled with ultrasound guidance during the session; report 19084 for each additional lesion biopsied with that same guidance modality. The record should identify the target and side, ultrasound localization, biopsy technique, tissue obtained, and any marker placement. Ultrasound guidance and specimen imaging are included in the service. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%; bilateral performance with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
