About 05NP4ZZ
05NP4ZZ is the ICD-10-PCS code for a release procedure on the right external jugular vein using a percutaneous endoscopic 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 05N04ZZ (azygos vein), 05N14ZZ (hemiazygos vein), 05N34ZZ (right innominate vein), 05N44ZZ (left innominate vein), 05N54ZZ (right subclavian vein), 05N64ZZ (left subclavian vein) and 19 more.
The same procedure with a different approach is coded 05NP0ZZ (open) and 05NP3ZZ (percutaneous).
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.
