What procedure is reported for an arterial catheterization performed by cutdown for transfusion?

The appropriate code for reporting an arterial catheterization performed by cutdown for transfusion is specific because it reflects both the method of accessing the artery and the purpose of the procedure. The cutdown technique involves a surgical incision and exposure of the artery, which is a more invasive approach than simply inserting a catheter percutaneously.

In this context, the code 36625 is correct because it specifically pertains to the insertion of an arterial catheter for transfusion purposes through a cutdown procedure. This code accounts for the additional complexity and risk inherent in the surgical cutdown method compared to other methods of arterial access.

Understanding the context of arterial catheterization is crucial; during transfusion, the artery must be accessed in a way that allows for effective blood flow and monitoring, and cutdown procedures are typically indicated when other methods are not feasible or safe. This code thus adequately captures the intricacies and requirements of the procedure performed.
