About 03BG3ZX
03BG3ZX is the ICD-10-PCS code for a excision procedure on the intracranial artery using a percutaneous 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 03B03ZX (right internal mammary artery), 03B13ZX (left internal mammary artery), 03B23ZX (innominate artery), 03B33ZX (right subclavian artery), 03B43ZX (left subclavian artery), 03B53ZX (right axillary artery) and 23 more.
The same procedure with a different approach is coded 03BG0ZX (open) and 03BG4ZX (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.
