About 03BS4ZX

03BS4ZX is the ICD-10-PCS code for a excision procedure on the right temporal 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 03BS0ZX (open) and 03BS3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 115 (Extraocular Procedures Except Orbit), DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC) and DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Extraocular Procedures Except Orbit”, “Other Ear, Nose, Mouth and Throat O.R. Procedures” and 5 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
