Official Description

Venous sampling through catheter, with or without angiography (eg, for parathyroid hormone, renin), radiological supervision and interpretation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 75893 refers to the procedure of venous sampling through a catheter, which may include angiography, accompanied by radiological supervision and interpretation. This procedure is typically performed to obtain blood samples from specific organs, which can be crucial for various diagnostic purposes, such as measuring levels of parathyroid hormone or renin. During this process, a physician utilizes a catheter to access a selected vein, allowing for the collection of blood samples that are essential for further analysis. The term 'radiological supervision and interpretation' indicates that the physician is responsible for overseeing the imaging aspects of the procedure, ensuring that the catheter is correctly placed and that the necessary images are captured for accurate assessment. The physician not only supervises the placement of the catheter but also monitors the flow of blood through the veins, which is vital for understanding the organ's blood supply. Additionally, if required, a radiopaque contrast agent may be injected to enhance the visibility of the vascular structures during angiography. After the procedure, the physician reviews the obtained radiographs and provides a comprehensive written interpretation of the findings, which is essential for guiding further clinical decisions.

1. Indications

The procedure described by CPT® Code 75893 is indicated for specific clinical scenarios where organ blood sampling is necessary. The following conditions may warrant this procedure:

  • Parathyroid Hormone Measurement This procedure may be performed to obtain blood samples for the assessment of parathyroid hormone levels, which can help diagnose conditions related to calcium metabolism and parathyroid function.
  • Renin Measurement Venous sampling may also be indicated for measuring renin levels, which is important in evaluating patients with hypertension or suspected adrenal disorders.

2. Procedure

The procedure involves several critical steps to ensure accurate venous sampling and effective radiological supervision. The following outlines the procedural steps:

  • Step 1: Catheter Placement The physician begins by selecting an appropriate vein for catheterization. Under sterile conditions, a catheter is inserted into the chosen vein, allowing access for blood sampling. The placement is guided by imaging techniques to ensure precision.
  • Step 2: Radiological Supervision Throughout the catheter placement, the physician provides radiological supervision, monitoring the procedure via imaging to confirm correct catheter positioning and to visualize the blood flow in the targeted region.
  • Step 3: Blood Sampling Once the catheter is securely in place, the physician obtains blood samples from the selected organ. These samples are critical for laboratory analysis and are collected in a manner that minimizes contamination and ensures accuracy.
  • Step 4: Angiography (if applicable) If indicated, a radiopaque contrast agent may be injected through the catheter to perform angiography. This step enhances the visualization of the vascular structures and allows for a detailed assessment of blood flow.
  • Step 5: Interpretation of Results After the procedure, the physician reviews the radiographs obtained during the angiography. A comprehensive interpretation of the imaging results is documented, providing essential information for further clinical evaluation and management.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any immediate complications related to catheter placement or blood sampling. The physician may provide specific instructions regarding activity restrictions and signs of potential complications, such as bleeding or infection at the catheter insertion site. Follow-up appointments may be scheduled to discuss the results of the blood tests and imaging studies, ensuring that any necessary further interventions or treatments are addressed promptly.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
GC This service has been performed in part by a resident under the direction of a teaching physician
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
