What 55874 covers
A urologist typically places biodegradable material, often a hydrogel spacer, in the tissue plane between the prostate and rectum before prostate radiation therapy. The added separation can help limit radiation exposure to the rectum. Placement is performed through the perineum with image guidance, commonly in an outpatient or hospital setting. The service may involve one or multiple deposits of material during the procedure.
Report 55874 for the spacer placement, including image guidance when performed; the code covers single or multiple placements in the session. The record should support the indication, transperineal placement, material used, and procedural details. It has a 0-day global period, so same-day preoperative and postoperative care is included. For procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeon or team-surgery payment requires supporting documentation.

55874 billing questions
Can 55874 be reported with prostate fiducial marker placement?
Yes, 55876 may be reported for distinct fiducial marker placement performed in the same session. Document each service separately; the CMS multiple-procedure reduction may apply to procedures performed together.
Does 55874 include image guidance?
Yes. Image guidance performed for the spacer placement is included in 55874.
How many units should be reported if the physician places multiple deposits?
The code covers single or multiple placements during the procedure. Multiple deposits in that session do not by themselves support multiple units.
Should modifier 50 be appended for placement on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What are the assistant-at-surgery and co-surgeon payment rules?
An assistant at surgery is not paid for this service under the stated statutory restriction. Co-surgeons or a surgical team are payable only with supporting documentation.
