What is procedure code 87210?

Procedure code 87210 is used in the Current Procedural Terminology codebook to report a procedure known as "arteriography, brachial or axillary arteries, unilateral, with injection(s) and radiological supervision and interpretation." This code is used to describe the procedure of injecting a contrast agent into the brachial or axillary artery, which are blood vessels in the upper arm, and then taking X-ray images to evaluate the blood flow to the affected area. The radiological supervision and interpretation component of the procedure involves a radiologist monitoring the procedure and interpreting the X-ray images to assess any abnormalities.
