About 02U54KZ

02U54KZ is the ICD-10-PCS code for a supplement procedure on the atrial septum using a percutaneous endoscopic approach with nonautologous 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 unspecified septal defect of heart with tissue graft, the ICD-9-CM procedure title it maps to (35.60).

For a different body part, codes include 02U04KZ (coronary artery, one artery), 02U14KZ (coronary artery, two arteries), 02U24KZ (coronary artery, three arteries), 02U34KZ (coronary artery, four or more arteries), 02U64KZ (right atrium), 02U74KZ (left atrium) and 19 more.

The same procedure with a different approach is coded 02U50KZ (open) and 02U53KZ (percutaneous).

With a different device, use 02U547Z (autologous tissue substitute), 02U548Z (zooplastic tissue) and 02U54JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.

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