Where 55920 pays more and less in Missouri
Radiation oncology
About 55920: Pelvic interstitial brachytherapy needle placement
Reports surgical placement of needles or catheters in pelvic organs or genital structures to prepare for interstitial radiation source application.
This service places needles or catheters in pelvic organs or genital structures in preparation for interstitial radiation. Target areas can include vaginal, perineal, urethral, or rectal tissue. A surgeon performs the placement, commonly a gynecologic oncologist or urologist depending on the anatomy and treatment plan, often in an operating room. The radiation oncologist coordinates the planned source application; placement itself is not radiation delivery.
Choose the code when the documented work is pelvic needle or catheter placement for subsequent interstitial treatment, rather than an intracavitary applicator or a prostate-specific placement. The operative report should identify the target anatomy, placement performed, and connection to the planned radiation treatment. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

55920 billing questions
How does 55920 differ from prostate needle placement?
Use 55920 for the described pelvic-organ or genital placement for interstitial radiation. Code 55875 is the prostate-specific placement service.
Is this the radiation source application?
No. This code represents needle or catheter placement for subsequent interstitial treatment, not delivery of the radioactive source.
When is modifier 50 appropriate?
It is not appropriate for 55920; CMS identifies bilateral adjustment as inapplicable to this code.
What documentation supports reporting 55920?
Document the pelvic target, the needle or catheter placement performed, and its purpose in the interstitial radiation plan.
Can an assistant-at-surgery be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
