The same procedure with a different approach is coded 0273366 (percutaneous) and 0273466 (percutaneous endoscopic).

With a different device, use 0273046 (intraluminal device, drug-eluting), 0273056 (intraluminal device, drug-eluting, two), 0273076 (intraluminal device, drug-eluting, four or more), 02730D6 (intraluminal device), 02730E6 (intraluminal device, two), 02730F6 (intraluminal device, three) and 3 more.
