What 57522 covers

A gynecologist uses an electrically energized wire loop to remove a cone-shaped section of cervical tissue. The specimen allows histologic evaluation while removing the targeted abnormal area. This procedure is commonly performed for high-grade cervical dysplasia, such as biopsy-confirmed CIN 2 or CIN 3, in an office procedure room, ambulatory surgery center, or hospital outpatient setting. The excised tissue is submitted for examination.

Select this code when the documented excision uses a loop electrode; a cold-knife or laser cone is reported differently. The operative note should support the indication, loop-electrode method, and tissue removed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

57522 billing questions

How is this different from code 57520?

Code 57522 is for conization performed with a loop electrode. Code 57520 represents a different conization method, such as cold-knife or laser excision.

Can a cervical biopsy be reported instead?

Use a biopsy code when tissue sampling, rather than loop-electrode cone excision, is performed. The method and extent documented in the procedure note distinguish the services.

Is cervical curettage separately reported with the conization?

The conization code accounts for associated curettage when performed as part of the procedure. Do not separately report that work as a distinct service.

Can modifier 50 be used for a bilateral procedure?

No. Modifier 50 is inappropriate for this cervical procedure.

Does Medicare pay an assistant or co-surgeon?

Medicare payment for an assistant at surgery is statutorily restricted. Co-surgeons and team surgery are not permitted for this code.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

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.
