Duplex Scan of Arterial Inflow and Venous Outflow (October 2019)

Why This Topic Matters

Accurate reporting of vascular mapping studies for hemodialysis access depends on knowing which code set applies, how the new CPT codes are positioned, and what related studies are referenced in the guidance. This article helps readers understand the scope of the change and where the new reporting framework fits within broader extremity vascular testing.
