About 039K0ZX
039K0ZX is the ICD-10-PCS code for a drainage procedure on the right internal carotid artery using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to biopsy of blood vessel, the ICD-9-CM procedure title it maps to (38.21).
For a different body part, codes include 03900ZX (right internal mammary artery), 03910ZX (left internal mammary artery), 03920ZX (innominate artery), 03930ZX (right subclavian artery), 03940ZX (left subclavian artery), 03950ZX (right axillary artery) and 23 more.
The same procedure with a different approach is coded 039K3ZX (percutaneous) and 039K4ZX (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.
