About 05NF3ZZ
05NF3ZZ is the ICD-10-PCS code for a release procedure on the left cephalic 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 05N03ZZ (azygos vein), 05N13ZZ (hemiazygos vein), 05N33ZZ (right innominate vein), 05N43ZZ (left innominate vein), 05N53ZZ (right subclavian vein), 05N63ZZ (left subclavian vein) and 19 more.
The same procedure with a different approach is coded 05NF0ZZ (open) and 05NF4ZZ (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.
