About 021K0ZF

021K0ZF is the ICD-10-PCS code for a bypass procedure on the right ventricle using an open approach (qualifier: abdominal artery). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to heart revascularization by arterial implant, the ICD-9-CM procedure title it maps to (36.2).

For a different body part, codes include 02100ZF (coronary artery, one artery), 02110ZF (coronary artery, two arteries), 02120ZF (coronary artery, three arteries), 02130ZF (coronary artery, four or more arteries) and 021L0ZF (left ventricle).

The same procedure with a different approach is coded 021K4ZF (percutaneous endoscopic).

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.
