About 021X0KP

021X0KP is the ICD-10-PCS code for a bypass procedure on the thoracic aorta, ascending/arch using an open approach with nonautologous tissue substitute (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 systemic to pulmonary artery shunt, the ICD-9-CM procedure title it maps to (39.0).

For a different body part, codes include 02160KP (right atrium), 02170KP (left atrium), 021K0KP (right ventricle), 021L0KP (left ventricle), 021V0KP (superior vena cava) and 021W0KP (thoracic aorta, descending).

The same procedure with a different approach is coded 021X4KP (percutaneous endoscopic).

With a different device, use 021X08P (zooplastic tissue), 021X09P (autologous venous tissue), 021X0AP (autologous arterial tissue), 021X0JP (synthetic substitute) and 021X0ZP (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical category “Other Major Cardiovascular Procedures”.

It was added in FY2017, effective October 1, 2016.
