What 58550 covers
A gynecologic surgeon uses laparoscopy to assist with a vaginal hysterectomy, removing the uterus through the vagina. This approach may be selected for conditions such as symptomatic fibroids, adenomyosis, or persistent abnormal uterine bleeding when the clinical plan and anatomy support vaginal removal. The code applies to a uterus weighing 250 g or less; the laparoscopic assistance is part of the hysterectomy service, not a separate procedure.
Select the code using the documented operative approach and uterine weight, supported by the operative report and specimen or pathology record. When removal of one or both tubes or ovaries is performed, the related code 58552 is the family option for a uterus of this size. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. Endoscopy-family pricing applies when related endoscopies are performed together. Modifier 50 is inappropriate. An assistant at surgery may be paid, and co-surgeons are permitted; team surgery is not permitted.

58550 billing questions
How does 58550 differ from 58552?
Both describe laparoscopic-assisted vaginal hysterectomy for a uterus of 250 g or less. Use 58552 when removal of one or both tubes or ovaries is included.
How is the 250 g threshold supported?
Document the operative approach and uterine weight in the operative and specimen or pathology records. The weight determines which size tier in the hysterectomy family applies.
Can the laparoscopic portion be billed separately?
The laparoscopic assistance is included in this hysterectomy service; it is not a separate laparoscopic procedure. CMS endoscopy-family pricing applies when related endoscopies are performed together.
Should modifier 50 be appended?
No. CMS identifies bilateral adjustment as inappropriate for this code because the descriptor or anatomy makes modifier 50 unsuitable.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
May an assistant or co-surgeon be reported?
CMS permits payment for an assistant at surgery and permits co-surgeons for this code. Team surgery is not permitted.
