About 36500: Selective organ venous blood sampling
Reports catheterization of selected organ-draining veins to collect blood samples, such as adrenal vein samples used in evaluation of primary aldosteronism.
A physician advances a catheter through the venous system into veins draining a selected organ and obtains blood samples for diagnostic testing. Interventional radiologists commonly perform this procedure in a hospital or outpatient setting. Adrenal vein sampling is a familiar example: samples from the adrenal veins help evaluate hormone production in a patient being assessed for primary aldosteronism.
Report 36500 for the selective organ-sampling catheterization, not for routine venous access or placement of a catheter for ongoing infusion. Documentation should identify the clinical purpose, target veins, catheterization performed, and samples obtained. Radiological supervision and interpretation may be separately represented by 75893 when supported. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.
CMS billing rules for 36500
- Global period

How this local rate is calculated
Each RVU component is multiplied by its own geographic practice cost index (GPCI). The three adjusted components are added, then multiplied by the conversion factor. These are the inputs used for 36500 in Indiana.

36500 billing questions
When is 36500 appropriate instead of a central venous catheter insertion code?
Use 36500 when the catheter is selectively advanced to organ-draining veins to collect diagnostic blood samples. A central venous catheter insertion code describes placement of central access, not selective organ sampling.
Can radiological supervision and interpretation be reported separately?
Code 75893 represents radiological supervision and interpretation for venous sampling through a catheter. Report it when the imaging service is performed and documentation supports it.
Should modifier 50 be appended when sampling both adrenal veins?
No. CMS identifies bilateral adjustment as inappropriate for 36500; sampling both sides does not make modifier 50 appropriate.
What documentation supports 36500?
Document the diagnostic purpose, the organ-draining veins selected, the catheterization performed, and the blood samples obtained. For adrenal vein sampling, the record should show the sampled adrenal veins.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's 0-day global period.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. CMS also restricts assistant-at-surgery payment and does not permit co-surgeons or team surgery for this code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
