2025 CPT code 75893

Venous sampling through a catheter, with or without angiography (e.g., for parathyroid hormone, renin), including radiological supervision and interpretation.

Refer to the current CPT coding guidelines for radiology procedures, specifically the guidelines for venography and radiological supervision and interpretation. Pay close attention to the rules for reporting diagnostic venography when performed in conjunction with interventional procedures.

Modifiers 26 (professional component only), TC (technical component only), 52 (reduced services), and others may apply depending on the circumstances of service provision. Consult the CPT modifier guidelines for appropriate application.

Medical necessity is established by a documented clinical indication for venous sampling, such as evaluating hormonal imbalances (hyperparathyroidism, renal artery stenosis, adrenal adenoma), or assessing other conditions requiring specific hormonal assays.

The clinical responsibility includes patient preparation, catheter insertion into the vein (potentially using fluoroscopy for guidance), angiography (if performed), blood aspiration, sample handling and sending it to the laboratory, catheter removal, hemostasis, and wound closure. The physician also provides radiological supervision and interpretation of the imaging studies.

IMPORTANT For the injection procedure for the venous system, see codes 36000-36015 and 36400-36510. For the injection procedure for the lymphatic system, use code 38790.If only the physician's interpretation is reported, append modifier 26. If only the technical component is reported, append modifier TC.If one provider supervises and another interprets, each should report the code with modifiers 52 and 26.

In simple words: The doctor inserts a thin tube (catheter) into a vein to take a blood sample.They may use imaging (like X-rays) to guide the tube and check the vein. The blood sample is sent to a lab for testing, such as checking hormone levels.

This CPT code encompasses venous sampling performed via catheter insertion, potentially incorporating angiography (vessel imaging) for diagnostic purposes.The procedure includes radiological supervision and interpretation of the images.Angiography may be used to visualize the vein and surrounding structures before, during, or after blood sampling.The collected venous blood sample is sent to a laboratory for analysis.The procedure may be indicated for assessing hormone levels such as parathyroid hormone (PTH) or renin.

Example 1: A patient presents with suspected hyperparathyroidism. Venous blood sampling is performed via catheterization to measure parathyroid hormone levels, guided by fluoroscopy and followed by radiological interpretation., A patient with suspected renal artery stenosis undergoes renal vein sampling to measure renin levels to help determine the diagnosis.Angiography is performed to assess the venous anatomy prior to sampling and is interpreted by the radiologist., A patient with a suspected adrenal vein adenoma needs venous sampling from the adrenal vein to measure hormone levels. Fluoroscopic guidance is used for catheterization, with post-procedure imaging interpretation.

Detailed medical history and clinical indication for venous sampling, description of the procedure, images (including fluoroscopy and angiography if performed), laboratory results of the blood sample, and any complications.
