About 37200: Transcatheter tissue biopsy
Reports tissue sampling performed through a catheter, commonly a transjugular liver biopsy when a standard percutaneous approach is unsuitable.
This code covers obtaining tissue with a biopsy device advanced through a catheter to the target site. A common application is transjugular liver biopsy, performed by an interventional radiologist when ascites or bleeding risk makes a standard percutaneous route unsuitable. The procedure is typically performed in a hospital or outpatient imaging suite with imaging used to guide the catheter and sampling device.
Select the code when the documented service is catheter-based tissue sampling, rather than direct needle biopsy through the skin. Record the target, vascular route, sampling performed, and relevant imaging. Radiological supervision and interpretation are represented separately by 75970 when that service is performed and documented. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures 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 is restricted, and co-surgeon and team-surgery billing are not permitted.

37200 billing questions
When should this code be used instead of a percutaneous liver biopsy code?
Use this code for tissue sampling performed with a catheter-based approach, such as transjugular liver biopsy. A needle passed directly through the skin is a different method and is not reported with this code.
Is radiological supervision and interpretation included?
Code 75970 represents the radiological supervision and interpretation service for transcatheter biopsy. Report it when that service is performed and documented.
Can modifier 50 be used for biopsies on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How does the multiple-procedure reduction affect another procedure in the session?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.
Can an assistant surgeon or co-surgeon be billed?
Assistant-at-surgery payment is restricted for this code. Co-surgeons and team surgery are not permitted.
