What 19084 covers

This add-on service covers biopsy of an additional distinct breast target identified and sampled with ultrasound guidance. A radiologist, breast surgeon, or other qualified physician may perform it in an outpatient imaging center, hospital, or office. The service includes ultrasound guidance and, when performed, marker placement and imaging of the specimen. It is selected by the imaging method used to guide the biopsy, not by the number of tissue cores taken from one target.

Report 19084 for each additional lesion beyond the first ultrasound-guided breast biopsy target, with 19083 serving as the primary code for the first lesion. The record should identify each separately sampled target and support ultrasound guidance for the additional biopsy. Multiple cores from one lesion do not represent multiple lesions. As an add-on code, 19084 is billed only with a primary procedure and its payment falls within that procedure's global period.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

19084 billing questions

When should 19084 be used instead of 19083?

Use 19083 for the first lesion biopsied with ultrasound guidance and 19084 for each additional distinct lesion biopsied with that guidance during the session.

Does each core from one lesion count as an additional lesion?

No. 19084 represents another distinct biopsy target, not additional tissue cores or passes from the same target.

What primary procedure is reported with 19084?

Report it with a primary breast biopsy procedure; 19083 is the corresponding primary code when the first lesion is biopsied under ultrasound guidance.

Are marker placement and specimen imaging included?

The service includes marker placement and specimen imaging when those steps are performed as part of the biopsy.

How does the global-period rule affect 19084?

It is an add-on code, not a stand-alone service, and its payment is within the global period of the associated primary procedure.
