# CPT 19083

> Medicare paid $589.34 for CPT 19083 in the office (non-facility) setting and $158.41 in a facility under the Q3 2021 Physician Fee Schedule, effective July 2021. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This price has been unchanged since Q1 2021, when it decreased 4.8%.

## What it is

A needle biopsy of a breast abnormality taken through the skin, with ultrasound used in real time to steer the needle into the target. The operator watches the needle on the ultrasound screen, collects small cores of tissue, and may leave a tiny metal marker at the site so the spot can be identified again later; an image of the removed tissue may also be taken to confirm the right area was sampled. Within this family of percutaneous breast biopsies, this one is defined by the imaging used to guide it, ultrasound rather than mammographic (stereotactic) or MRI guidance, and it covers the first abnormality sampled during the session; additional targets in the same session are reported separately.
