About 03B94ZX
03B94ZX is the ICD-10-PCS code for a excision procedure on the right ulnar artery using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of 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 03B04ZX (right internal mammary artery), 03B14ZX (left internal mammary artery), 03B24ZX (innominate artery), 03B34ZX (right subclavian artery), 03B44ZX (left subclavian artery), 03B54ZX (right axillary artery) and 23 more.
The same procedure with a different approach is coded 03B90ZX (open) and 03B93ZX (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.
