What 57505 covers

A clinician uses a curette to collect tissue from inside the cervical canal for histologic examination. Gynecologists commonly perform this sampling in an office or outpatient setting when evaluating abnormal cervical screening results or colposcopic findings, including situations where assessment of the canal is needed. The specimen is submitted for pathology; this service samples the canal rather than removing a larger portion of the cervix.

Report the service when canal curettage is performed and is not already included in a more comprehensive colposcopy code, such as 57454 or 57456. Document the indication, the sampling performed, and any separately obtained cervical biopsy. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed 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 not appropriate for this single midline canal. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgeons 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.

57505 billing questions

Can 57505 be reported with a colposcopy?

Report it separately when endocervical curettage is performed with a colposcopy code that does not include that sampling, such as 57455. Do not separately report it with 57454 or 57456, which include endocervical curettage.

How is this different from a cervical biopsy?

Endocervical curettage samples tissue from within the cervical canal. A cervical biopsy, such as 57500, removes tissue from a specific cervical site or lesion.

What documentation supports reporting 57505?

Document the clinical reason for canal sampling and that curettage was performed, along with the specimen obtained. If a separate cervical biopsy was also done, document that sampling distinctly.

Should modifier 50 be appended?

No. The cervical canal is a single midline site, so bilateral reporting with modifier 50 is not appropriate.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full; other procedures performed in the same session are subject to the standard multiple procedure reduction. Related postoperative visits during the 10-day global period are included.

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.
