About 021W0JR

021W0JR is the ICD-10-PCS code for a bypass procedure on the thoracic aorta, descending using an open approach with synthetic substitute (qualifier: left pulmonary 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 systemic to pulmonary artery shunt, the ICD-9-CM procedure title it maps to (39.0).

For a different body part, codes include 02160JR (right atrium), 02170JR (left atrium), 021K0JR (right ventricle), 021L0JR (left ventricle), 021V0JR (superior vena cava) and 021X0JR (thoracic aorta, ascending/arch).

The same procedure with a different approach is coded 021W4JR (percutaneous endoscopic).

With a different device, use 021W08R (zooplastic tissue), 021W09R (autologous venous tissue), 021W0AR (autologous arterial tissue), 021W0KR (nonautologous tissue substitute) and 021W0ZR (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
