What 57456 covers

A clinician uses a colposcope to examine the cervix and nearby vaginal tissue, then collects tissue from the endocervical canal with a curette. This is commonly performed by a gynecologist in an office or outpatient setting during evaluation of abnormal cervical cytology or a high-risk HPV result. The canal sample is submitted for pathology; this service includes endocervical curettage, not a separate cervical biopsy.

Report this code when colposcopy is accompanied by endocervical curettage without cervical biopsy. When cervical biopsy and curettage are both performed, the code that includes both services is 57454. Document the indication, colposcopic findings, curettage, and specimen. CMS assigns a 0-day global period, including same-day preoperative and postoperative care. Endoscopy-family pricing applies when related endoscopies are performed together. A bilateral adjustment is inappropriate; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery payment 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.

57456 billing questions

When should 57456 be chosen instead of 57454?

Use 57456 for colposcopy with endocervical curettage but no cervical biopsy. When both cervical biopsy and curettage are performed, report 57454, which includes both.

Can cervical biopsy be billed separately with 57456?

If a cervical biopsy is performed during the colposcopy along with the curettage, 57454 represents that combination. Do not separately report the biopsy and curettage components.

What documentation supports this code?

Document the reason for colposcopy, cervical and adjacent vaginal findings, performance of endocervical curettage, and the specimen submitted for pathology.

Does 57456 have a global period?

CMS assigns a 0-day global period. Same-day preoperative and postoperative care is included.

Can an assistant or co-surgeon be reported?

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

How is 57456 priced with another related endoscopy?

When related endoscopies are performed together, CMS applies endoscopy-family pricing. The payment reflects that pricing rule rather than treating every related scope as an independently priced full service.

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.
