What 57520 covers

This code describes removal of a cone-shaped section of cervical tissue by a non-loop excisional method, commonly cold-knife conization. A gynecologist may perform it in an operating room when cervical dysplasia, glandular abnormalities, or concern for an occult lesion calls for a larger, oriented specimen that includes the transformation zone and endocervical canal. The tissue is submitted for histopathologic examination to assess the lesion and margins.

Choose this code for a non-loop cone excision, not a loop-electrode excision. The operative report should support the indication, method, tissue removed, and any associated steps. Fulguration, dilation and curettage, and repair may be part of the coded service when performed with the cone. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Modifier 50 is inappropriate for this single cervical excision. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

57520 billing questions

How does this differ from 57522?

Use 57520 for a non-loop cone excision, commonly performed with a cold knife. Code 57522 describes cone excision using a loop electrode.

Can endocervical curettage be billed separately?

Curettage performed as part of the cone service is included in the code’s scope. Do not separately report the same-session curettage as a distinct service merely because it is documented.

When is 57500 more appropriate?

Code 57500 describes a cervical biopsy rather than removal of a cone-shaped section. Choose 57520 when the surgeon performs the larger excisional cone.

What documentation supports 57520?

Document the clinical indication, non-loop excision method, tissue removed, and operative steps. The record should make clear that the service was a cone excision rather than a limited biopsy or loop procedure.

Does the procedure have a global period?

Yes. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this code, and 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.
