About 02SW0ZZ

02SW0ZZ is the ICD-10-PCS code for a reposition procedure on the thoracic aorta, descending using an open approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to other repair of vessel, the ICD-9-CM procedure title it maps to (39.59).

For a different body part, codes include 02S00ZZ (coronary artery, one artery), 02S10ZZ (coronary artery, two arteries), 02SP0ZZ (pulmonary trunk), 02SQ0ZZ (right pulmonary artery), 02SR0ZZ (left pulmonary artery), 02SS0ZZ (right pulmonary vein) and 3 more.

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), DRG 254 (Other Vascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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