About 06N33ZZ

06N33ZZ is the ICD-10-PCS code for a release procedure on the esophageal vein using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to Freeing of vessel, the ICD-9-CM procedure title it maps to (39.91).

For a different body part, codes include 06N03ZZ (inferior vena cava), 06N13ZZ (splenic vein), 06N23ZZ (gastric vein), 06N43ZZ (hepatic vein), 06N53ZZ (superior mesenteric vein), 06N63ZZ (inferior mesenteric vein) and 17 more.

The same procedure with a different approach is coded 06N30ZZ (open) and 06N34ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

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