About 02U508Z

02U508Z is the ICD-10-PCS code for a supplement procedure on the atrial septum using an open approach with zooplastic tissue. 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 atrial septal defect with tissue graft, the ICD-9-CM procedure title it maps to (35.61).

For a different body part, codes include 02U008Z (coronary artery, one artery), 02U108Z (coronary artery, two arteries), 02U208Z (coronary artery, three arteries), 02U308Z (coronary artery, four or more arteries), 02U608Z (right atrium), 02U708Z (left atrium) and 19 more.

The same procedure with a different approach is coded 02U538Z (percutaneous) and 02U548Z (percutaneous endoscopic).

With a different device, use 02U507Z (autologous tissue substitute), 02U50JZ (synthetic substitute) and 02U50KZ (nonautologous tissue 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.
