About 06L33CZ

06L33CZ is the ICD-10-PCS code for a occlusion procedure on the esophageal vein using a percutaneous approach with extraluminal device. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other operations on esophagus, the ICD-9-CM procedure title it maps to (42.99).

For a different body part, codes include 06L03CZ (inferior vena cava), 06L13CZ (splenic vein), 06L23CZ (gastric vein), 06L43CZ (hepatic vein), 06L53CZ (superior mesenteric vein), 06L63CZ (inferior mesenteric vein) and 17 more.

The same procedure with a different approach is coded 06L30CZ (open), 06L34CZ (percutaneous endoscopic), 06L37CZ (via natural or artificial opening) and 06L38CZ (via natural or artificial opening endoscopic).

With a different device, use 06L33DZ (intraluminal device) and 06L33ZZ (no device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
