Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 36500 covers

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.
