About 021L0JR

021L0JR is the ICD-10-PCS code for a bypass procedure on the left ventricle 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 heart revascularization by arterial implant, the ICD-9-CM procedure title it maps to (36.2).

For a different body part, codes include 02160JR (right atrium), 02170JR (left atrium), 021K0JR (right ventricle), 021V0JR (superior vena cava), 021W0JR (thoracic aorta, descending) and 021X0JR (thoracic aorta, ascending/arch).

The same procedure with a different approach is coded 021L4JR (percutaneous endoscopic).

With a different device, use 021L08R (zooplastic tissue), 021L09R (autologous venous tissue), 021L0AR (autologous arterial tissue), 021L0KR (nonautologous tissue substitute) and 021L0ZR (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
