About 06L37CZ

06L37CZ is the ICD-10-PCS code for a occlusion procedure on the esophageal vein using a via natural or artificial opening 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 ligation of esophageal varices, the ICD-9-CM procedure title it maps to (42.91).

For a different body part, codes include 06L27CZ (gastric vein) and 06LY7CZ (lower vein).

The same procedure with a different approach is coded 06L30CZ (open), 06L33CZ (percutaneous), 06L34CZ (percutaneous endoscopic) and 06L38CZ (via natural or artificial opening endoscopic).

With a different device, use 06L37DZ (intraluminal device) and 06L37ZZ (no device).

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

It was added in FY2018, effective October 1, 2017.
