What 49185 covers
This service treats a defined fluid collection by percutaneously placing a needle or catheter and instilling a sclerosant to promote closure of the cavity. Typical targets include a lymphocele, cyst, or seroma. An interventional radiologist commonly performs the procedure in a hospital or outpatient setting, using imaging to access and treat the collection. The service includes contrast injection and radiological supervision and interpretation.
Report 49185 when the procedure is sclerotherapy of a fluid collection, rather than drainage alone, tissue sampling, or open removal. Documentation should identify the collection, describe percutaneous access and sclerosant treatment, and support the imaging and contrast work performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

49185 billing questions
When should 49185 be selected instead of a fluid-collection drainage code?
Use 49185 when the clinician performs percutaneous sclerotherapy to treat the collection. Drainage codes describe catheter drainage, not sclerosant treatment.
Are imaging guidance and contrast reported separately?
The service includes contrast injection and radiological supervision and interpretation. Do not separately report those elements as separate services for the same sclerotherapy procedure.
Can modifier 50 be used for collections on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Can an assistant, co-surgeon, or surgical team be paid?
Medicare does not pay an assistant at surgery for 49185. Co-surgeons and team surgery are not permitted.
What documentation supports reporting 49185?
Document the type and location of the collection, percutaneous access, sclerosant treatment, and imaging and contrast work. The record should make clear that the service was sclerotherapy rather than drainage alone.
What care is included in the global period?
The code has a 0-day global period. Same-day preoperative and postoperative care is included.
