What 57400 covers
A gynecologist typically performs this procedure when vaginal narrowing or stenosis makes the canal difficult to examine or access. Under anesthesia, the clinician uses dilation to widen the vaginal canal; this is a therapeutic procedure, not simply a pelvic examination or vaginal endoscopy. It may be performed in a hospital or other procedural setting, and the clinical record should identify the narrowing and the reason dilation was needed.
Report the service when the documented work is dilation of the vagina, rather than dilation of the cervical canal. The operative note should support the indication and describe the procedure performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is 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% multiple-procedure reduction. Bilateral adjustment is not appropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

57400 billing questions
How is vaginal dilation different from cervical dilation?
57400 is for dilation of the vaginal canal. Use 57800 when the procedure dilates the cervical canal instead.
Is this code for a pelvic examination under anesthesia?
No. Report 57400 when therapeutic vaginal dilation is performed; 57410 describes a pelvic examination under anesthesia.
Does the code have a global period?
It has a 0-day global period. Same-day preoperative and postoperative care is included.
Can modifier 50 be used?
No. CMS specifies that bilateral adjustment does not apply because the descriptor or anatomy makes modifier 50 inappropriate.
When can an assistant-at-surgery be paid?
Assistant-at-surgery payment is available only when the record documents medical necessity. Co-surgeons and team surgery are not permitted.
How does payment work when another procedure is performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard 50% multiple-procedure reduction.
