About 021K08P

021K08P is the ICD-10-PCS code for a bypass procedure on the right ventricle using an open approach with zooplastic tissue (qualifier: pulmonary trunk). 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 creation of conduit between right ventricle and pulmonary artery, the ICD-9-CM procedure title it maps to (35.92).

For a different body part, codes include 021608P (right atrium), 021708P (left atrium), 021L08P (left ventricle), 021V08P (superior vena cava), 021W08P (thoracic aorta, descending) and 021X08P (thoracic aorta, ascending/arch).

The same procedure with a different approach is coded 021K48P (percutaneous endoscopic).

With a different device, use 021K09P (autologous venous tissue), 021K0AP (autologous arterial tissue), 021K0JP (synthetic substitute), 021K0KP (nonautologous tissue substitute) and 021K0ZP (no device).

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 was added in FY2017, effective October 1, 2016.
