In which situation would you use code 96523?

Code 96523 is specifically used for the administration of a therapeutic drug by a method that involves injecting it into a central venous access device (CVAD). This code precisely describes the process of irrigation, which is a common practice to maintain the patency of a venous access device.

In this context, irrigation serves to clear any blockages and prevent clotting, which is crucial for maintaining effective access for subsequent therapies. This is distinct from other situations like surgical procedures, radiation therapy, or lab tests, which have specific codes designated for those different contexts. By focusing on the administration related to a venous access device, 96523 accurately captures the nature of the service provided, adhering to the coding guidelines that categorize procedures according to their specific applications.
