What 55300 covers
A urologist makes an opening in the vas deferens to allow contrast to be introduced for vasography. The procedure may be part of an infertility evaluation when imaging is needed to assess the reproductive ducts, such as for suspected obstruction. The surgical access is distinct from the radiologic interpretation of the resulting study, which may be reported separately when supported by the services performed.
Report 55300 for the vasotomy performed to enable vasography, whether unilateral or bilateral; the code is priced bilaterally, so modifier 50 does not increase payment. Document the indication, side or sides treated, and the operative work supporting access for contrast imaging. The service has a 0-day global period, with same-day preoperative and postoperative care included. 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. Assistant-at-surgery payment requires medical-necessity documentation. Co-surgeon and team-surgery payment are not permitted.

55300 billing questions
Should modifier 50 be appended when both vas deferens are accessed?
The code is priced as bilateral, and modifier 50 does not increase payment. Document the side or sides treated.
Is the imaging interpretation included in 55300?
55300 represents the surgical access for contrast imaging. The radiological supervision and interpretation may be separately reported with 74440 when that service is performed and documented.
How does 55300 differ from a vasectomy?
55300 creates access for diagnostic vasography. A vasectomy is performed to interrupt the vas deferens for sterilization.
What documentation supports reporting 55300?
Record the diagnostic reason for vasography, the side or sides treated, and the operative steps used to open the vas deferens for contrast access.
Can an assistant-at-surgery be reported?
Assistant-at-surgery payment is available only when medical necessity is documented. Co-surgeon and team-surgery payment are not permitted for this code.
