About 02UM37Z

02UM37Z is the ICD-10-PCS code for a supplement procedure on the ventricular septum using a percutaneous 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 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 02U037Z (coronary artery, one artery), 02U137Z (coronary artery, two arteries), 02U237Z (coronary artery, three arteries), 02U337Z (coronary artery, four or more arteries), 02U537Z (atrial septum), 02U637Z (right atrium) and 19 more.

The same procedure with a different approach is coded 02UM07Z (open) and 02UM47Z (percutaneous endoscopic).

With a different device, use 02UM38Z (zooplastic tissue), 02UM3JZ (synthetic substitute) and 02UM3KZ (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.
