What 57420 covers
Code 57420 represents magnified inspection of vaginal mucosa with a colposcope, without tissue sampling. Gynecologists commonly perform it in an office or outpatient setting to assess abnormal vaginal cytology or a visible lesion, including possible vaginal intraepithelial neoplasia. Document the indication, areas examined, adequacy of visualization, and findings.
Report this code when the colposcopic assessment is directed to the vagina and no vaginal biopsy is taken. If vaginal tissue is biopsied during colposcopy, use 57421. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are reduced to 50%. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery payment is 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.

57420 billing questions
When should 57420 be reported instead of 57421?
Use 57420 for vaginal colposcopy without vaginal tissue sampling. When a vaginal biopsy is performed during the colposcopy, report 57421.
How does 57420 differ from cervical colposcopy?
57420 describes colposcopic assessment directed to the vagina. For an examination directed to the cervix, consider the cervical colposcopy code that matches the services performed.
Is a vaginal biopsy separately reported with 57420?
When vaginal tissue is biopsied during colposcopy, 57421 describes the vaginal colposcopy with biopsy; do not report 57420 for that same service.
Can modifier 50 be used for bilateral vaginal colposcopy?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not appropriate.
What same-day payment rules affect 57420?
The 0-day global period includes same-day preoperative and postoperative care. In a session with multiple procedures, the highest-valued procedure is paid in full and the others are reduced to 50%; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.
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.
