What 57452 covers

A gynecologist or other qualified clinician uses a colposcope to examine the cervix and upper adjacent vagina, commonly after an abnormal cervical screening result or during evaluation of a suspected cervical lesion. The examination may include applying a solution to make abnormal areas easier to see, but this service is limited to visual assessment without cervical biopsy or endocervical curettage. It is performed in office and outpatient settings.

Report this code when the documented service is colposcopic inspection without tissue sampling; select a related code when cervical biopsy, endocervical curettage, or both are performed. The record should identify the reason for examination and document the cervical and adjacent vaginal findings. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When this service is performed in the same session as another procedure subject to multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery, and 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.

57452 billing questions

When should I report this instead of a cervical biopsy colposcopy code?

Use this code for colposcopic inspection without cervical biopsy or endocervical curettage. If sampling is performed, select the code that matches the sampling.

Can I report this when an endocervical curettage is performed?

No. This code describes visual examination without tissue sampling; use the applicable colposcopy code when endocervical curettage is performed.

Does the examination include the vagina?

It includes examination of the upper adjacent vagina along with the cervix. A colposcopic examination focused on the vagina rather than the cervix is represented by a different code.

Is modifier 50 appropriate?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How does the multiple procedure reduction affect payment?

For procedures subject to the standard reduction performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%.

Can an assistant or co-surgeon be paid for this 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.
