What 19287 covers

A radiologist typically uses MRI to guide a needle or delivery system through the skin and place a localization device at a breast lesion. The marker helps identify the target for a later procedure, such as surgical excision, particularly when the abnormality is best seen on MRI. This code represents localization, not tissue sampling; it may be performed after a prior biopsy has identified the target.

Report this code for the first lesion localized with MRI guidance, and document the target, percutaneous placement, and MRI guidance. The add-on code 19288 is used for each additional lesion. MRI guidance for placement is included. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

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.

19287 billing questions

When should 19287 be used instead of 19288?

Use 19287 for the first lesion localized with MRI guidance. Report 19288 for each additional lesion.

How does 19287 differ from 19285?

Both describe percutaneous breast localization device placement, but 19287 uses MRI guidance and 19285 uses ultrasound guidance.

Can 19287 be reported for a breast biopsy?

19287 describes placement of a localization device, not tissue sampling. For an MRI-guided percutaneous biopsy with marker placement, consider 19085, which includes the biopsy service.

Is MRI guidance separately reported with 19287?

No. MRI guidance for the localization placement is included in 19287.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
