What 19000 covers

A clinician uses a needle to withdraw fluid from a breast cyst, commonly one that is palpable, uncomfortable, or identified on imaging. The service may be performed in an office or facility by a physician involved in breast care, such as a breast surgeon or radiologist. Aspiration removes cyst fluid; it is distinct from taking a core tissue sample from a breast lesion.

Report 19000 for the first cyst aspirated in the session and 19001 for each additional cyst. Document the cyst’s location, the clinical reason for aspiration, and the aspiration performed; identify additional cysts when reporting the add-on code. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and 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.

19000 billing questions

When should 19001 be reported instead of 19000?

Report 19000 for the first breast cyst aspirated. Report 19001 for each additional cyst aspirated during the session.

Is cyst aspiration the same as a breast core biopsy?

No. Aspiration withdraws fluid from a cyst; a core biopsy obtains tissue from a lesion. Use the code that reflects the service actually performed.

Can modifier 50 be used when cysts in both breasts are aspirated?

No. CMS identifies bilateral adjustment as inappropriate for this code, so do not use modifier 50.

Does 19000 have a global period?

It has a 0-day global period. Same-day preoperative and postoperative care is included.

How does the multiple-procedure rule affect 19000?

When it is performed with other procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.

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.
