About 03U147Z

03U147Z is the ICD-10-PCS code for a supplement procedure on the left internal mammary artery using a percutaneous endoscopic approach with autologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to repair of blood vessel with tissue patch graft, the ICD-9-CM procedure title it maps to (39.56).

For a different body part, codes include 03U047Z (right internal mammary artery), 03U247Z (innominate artery), 03U347Z (right subclavian artery), 03U447Z (left subclavian artery), 03U547Z (right axillary artery), 03U647Z (left axillary artery) and 23 more.

The same procedure with a different approach is coded 03U107Z (open) and 03U137Z (percutaneous).

With a different device, use 03U14JZ (synthetic substitute) and 03U14KZ (nonautologous tissue substitute).

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.
