What 57800 covers
A clinician, typically a gynecologist, uses graduated dilators or another appropriate technique to open the cervical canal. The service may address cervical stenosis or provide access when the dilation itself is a distinct clinical objective. It is performed in settings such as an office procedure room, ambulatory surgery center, or operating room. Dilation performed only to pass instruments for a more extensive procedure is generally part of that procedure, not a separate service.
Report 57800 when the record supports a distinct cervical dilation, including the indication and the work performed. This is a minor procedure with 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% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

57800 billing questions
When should 57800 be reported instead of a hysteroscopy code?
Use 57800 for a distinct cervical dilation. When dilation is performed only to permit hysteroscope access, report the hysteroscopy service rather than separately reporting the access step.
Can cervical dilation be billed with a D&C?
Dilation performed to access the uterus for a dilation and curettage is generally integral to the D&C. Do not separately report 57800 for that access step.
What documentation supports 57800?
Document the reason for dilation, such as cervical stenosis, and describe the dilation performed. The note should make clear when it was a distinct service rather than access for another procedure.
Should modifier 50 be appended for dilation of both sides?
No. Modifier 50 is inappropriate for this code.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's 0-day global period.
Can an assistant or co-surgeon be paid for this procedure?
Medicare does not pay an assistant at surgery for 57800. Co-surgeons and team surgery are not permitted.
