About 031M0ZJ

031M0ZJ is the ICD-10-PCS code for a bypass procedure on the right external carotid artery using an open approach (qualifier: right extracranial artery). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to other (peripheral) vascular shunt or bypass, the ICD-9-CM procedure title it maps to (39.29).

For a different body part, codes include 03120ZJ (innominate artery), 03130ZJ (right subclavian artery), 03140ZJ (left subclavian artery), 03150ZJ (right axillary artery), 03160ZJ (left axillary artery), 031H0ZJ (right common carotid artery) and 4 more.

With a different device, use 031M09J (autologous venous tissue), 031M0AJ (autologous arterial tissue), 031M0JJ (synthetic substitute) and 031M0KJ (nonautologous tissue substitute).

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 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical categories “Extracranial Procedures”, “Other Respiratory System O.R. Procedures”, “Other Vascular Procedures” and 5 more.

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