What 55845 covers
A urologist uses an open retropubic approach to remove the prostate for cancer and dissect pelvic lymph nodes on both sides, including the external iliac, hypogastric, and obturator basins. The code fits an operation that includes this extensive nodal dissection, rather than prostate removal alone or a less extensive node dissection. These procedures are generally performed in a hospital operating room.
Report the code when the operative note supports the retropubic approach, radical prostate removal, bilateral dissection, and the specified nodal basins. The bilateral work is built into the code; modifier 50 does not increase payment. The day-before preoperative visit and 90 days of related postoperative care are included in the global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

55845 billing questions
How does this differ from 55842?
55845 is for the more extensive bilateral nodal dissection that includes the external iliac, hypogastric, and obturator basins. Use 55842 when the documented bilateral pelvic dissection is more limited.
Should modifier 50 be added for the bilateral dissection?
No. The code is priced for bilateral work, and modifier 50 does not increase payment.
Can the lymph-node dissection be billed separately?
The bilateral dissection of the specified pelvic basins is included in this procedure. The operative note should establish the extent of nodal work supporting this code.
What postoperative care is included?
The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted for this code.
How is this distinguished from 55866?
55845 describes an open retropubic operation. Code 55866 is for a laparoscopic radical prostatectomy, including when performed with robotic assistance.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
