What 57550 covers
This procedure removes the remaining cervix through the vagina, typically in a patient who previously had a supracervical hysterectomy and still has a cervical stump. A gynecologic surgeon may perform it for a documented problem involving that remnant, such as persistent bleeding or cervical disease. The operative report should make clear that the target is residual cervix and that the vaginal route was used.
Report 57550 for vaginal removal of the cervical stump; an abdominal approach is represented by a different code. Documentation should identify the prior surgery, the indication, the anatomy removed, and the operative approach. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this single midline structure. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

57550 billing questions
When should 57550 be chosen over 57540?
Use 57550 when the residual cervix is removed through a vaginal approach. Code 57540 describes removal of the cervical stump through an abdominal approach.
Is 57550 used for a cervical conization?
No. It represents removal of a residual cervical stump, not an excision of cervical tissue for conization. A conization code such as 57520 or 57522 describes that different service.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code because the anatomy and service do not support bilateral reporting.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care through the 90-day period.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.
What documentation supports assistant or co-surgeon billing?
The operative record should support the assistant's role. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
