What 19284 covers

This add-on represents percutaneous placement of a localization device, such as a clip or marker, in an additional breast lesion using stereotactic imaging guidance. Breast radiologists and other clinicians who perform image-guided breast procedures commonly place these devices in a breast imaging center or hospital before surgical excision, including when more than one lesion needs localization.

Report 19284 for each additional lesion after the first stereotactically localized lesion, and pair it with 19283 for the first lesion. The record should identify the separately targeted lesions, the stereotactic guidance used, and the device placement at each site. The code includes the stereotactic guidance for the additional placement. CMS classifies 19284 as an add-on code: it 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.

19284 billing questions

When should 19284 be reported instead of 19283?

Use 19283 for the first lesion localized with stereotactic guidance. Report 19284 for each additional lesion localized by that method.

What primary code must accompany 19284?

Report 19284 with 19283, which represents the first stereotactically localized lesion. The add-on code is not reported by itself.

Can 19284 be used for an ultrasound-guided lesion?

No. For an additional lesion localized with ultrasound guidance, use 19286 rather than 19284.

Is stereotactic guidance separately reported for the additional placement?

The stereotactic guidance is included in 19284. The code accounts for the guidance used to place the device in the additional lesion.

What documentation supports reporting multiple units?

Document each distinct lesion receiving a device and the stereotactic guidance used. Report 19284 for each additional lesion beyond the first, alongside 19283.

How does the global-period rule affect payment?

CMS treats 19284 as an add-on paid within the primary procedure's global period. It must accompany the primary procedure rather than stand alone.

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.
