What 58100 covers

A clinician obtains tissue from the uterine lining for evaluation, commonly for abnormal uterine bleeding, postmenopausal bleeding, or concern for endometrial hyperplasia or cancer. The sample may be collected by aspiration or another method, and endocervical sampling may be included. Gynecologists commonly perform this procedure in an office or outpatient facility, often using a narrow sampling device passed through the cervix without dilation.

Report the service when endometrial sampling is performed without cervical dilation; documentation should identify the indication, sampling performed, and method when relevant. The code has 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% multiple procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; 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.

58100 billing questions

When should this code be chosen over 58120?

Use 58100 for endometrial sampling without cervical dilation. Code 58120 describes dilation and curettage, rather than sampling without dilation.

Can endocervical sampling be included?

Yes. The service may include endocervical sampling along with the uterine lining sample; document which tissue was obtained.

Should modifier 50 be appended for sampling both sides?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this service.

What documentation supports reporting 58100?

Document the clinical reason for sampling, that endometrial tissue was obtained, and that cervical dilation was not performed. Record any endocervical sampling as well.

How does the 0-day global period affect same-day care?

Same-day preoperative and postoperative care is included in the procedure's payment.

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.
