About 035M0ZZ
035M0ZZ is the ICD-10-PCS code for a destruction procedure on the right external carotid artery using an open approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.
In plain terms, this corresponds to other excision of vessels, other vessels of head and neck, the ICD-9-CM procedure title it maps to (38.62).
For a different body part, codes include 03500ZZ (right internal mammary artery), 03510ZZ (left internal mammary artery), 03520ZZ (innominate artery), 03530ZZ (right subclavian artery), 03540ZZ (left subclavian artery), 03550ZZ (right axillary artery) and 23 more.
The same procedure with a different approach is coded 035M3ZZ (percutaneous) and 035M4ZZ (percutaneous endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 037 (Extracranial Procedures with MCC), DRG 038 (Extracranial Procedures with CC), DRG 039 (Extracranial Procedures without CC/MCC), 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 categories “Extracranial Procedures”, “Other Vascular Procedures” and “Other O.R. Procedures for Injuries”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
