About 06L37ZZ

06L37ZZ is the ICD-10-PCS code for a occlusion procedure on the esophageal vein using a via natural or artificial opening approach. 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 06L27ZZ (gastric vein) and 06LY7ZZ (lower vein).

The same procedure with a different approach is coded 06L30ZZ (open), 06L33ZZ (percutaneous), 06L34ZZ (percutaneous endoscopic) and 06L38ZZ (via natural or artificial opening endoscopic).

With a different device, use 06L37CZ (extraluminal device) and 06L37DZ (intraluminal 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.
