About the X27 Code Range
These procedures widen an opening or the inside of a blood vessel. The vessels include the thoracic aorta, pulmonary arteries, inferior vena cava, and named arteries and veins.
The fourth character names the vessel and, for many vessels, its right or left side. The fifth character is Percutaneous, meaning instruments reach the site through a skin puncture or small incision. The sixth identifies a device placed inside the vessel: cell-impermeable, expandable, open-structure polymer lattice, small-diameter, or an everolimus-releasing scaffold that can be absorbed. The seventh character identifies New Technology Group 10, 11, or 12.
FY 2027 changes: The FY 2027 ICD-10-PCS update, effective October 1, 2026, added X2723CB, X27P3NC, X27Q3NC, X27R3NC, X27S3NC, X27T3NC and X27U3NC.
