What 55840 covers

A urologist typically performs this open operation through a lower abdominal incision to remove the prostate as radical treatment, commonly for prostate cancer. Nerve-sparing dissection may be performed when clinically appropriate. This code identifies the retropubic approach without the bilateral pelvic lymphadenectomy variants in the same code family; the operative report should support the approach, extent of prostate removal, and whether nerve sparing was performed.

Report the code when the documented operation matches the open retropubic radical procedure, rather than a perineal or laparoscopic approach or a lymphadenectomy variant. CMS assigns a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

55840 billing questions

How is this code distinguished from 55810?

Both describe radical prostatectomy, but 55840 is the open retropubic approach and 55810 is the perineal approach. Use the approach documented in the operative report.

Which code applies when bilateral pelvic lymphadenectomy is performed?

Use the applicable lymphadenectomy variant in the 55840 family, such as 55842 or 55845, rather than reporting 55840 for that operative configuration.

Does nerve sparing change the code selection?

No. This code includes the retropubic radical procedure whether or not nerve-sparing dissection is performed.

What postoperative care is included in the global period?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

CMS may pay for an assistant at surgery. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
