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.

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.

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%.
