03LM3CZOcclusion of Right External Carotid Artery with Extraluminal Device, Percutaneous Approach

03LM3CZ is the ICD-10-PCS code for a occlusion procedure on the right external carotid artery using a percutaneous approach with extraluminal device. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other surgical occlusion of vessels, other vessels of head and neck, the ICD-9-CM procedure title it maps to (38.82).

For a different body part, codes include 03L03CZ (right internal mammary artery), 03L13CZ (left internal mammary artery), 03L23CZ (innominate artery), 03L33CZ (right subclavian artery), 03L43CZ (left subclavian artery), 03L53CZ (right axillary artery) and 23 more.

The same procedure with a different approach is coded 03LM0CZ (open) and 03LM4CZ (percutaneous endoscopic).

With a different device, use 03LM3BZ (intraluminal device, bioactive), 03LM3DZ (intraluminal device) and 03LM3ZZ (no device).

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 140 (Major Head and Neck Procedures with MCC), DRG 141 (Major Head and Neck Procedures with CC) and DRG 142 (Major Head and Neck Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Major Head and Neck Procedures”, “Other Vascular Procedures” and 2 more.

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