About 02174JQ

02174JQ is the ICD-10-PCS code for a bypass procedure on the left atrium using a percutaneous endoscopic approach with synthetic substitute (qualifier: right 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 creation of conduit between atrium and pulmonary artery, the ICD-9-CM procedure title it maps to (35.94).

For a different body part, codes include 02164JQ (right atrium), 021K4JQ (right ventricle), 021L4JQ (left ventricle), 021V4JQ (superior vena cava), 021W4JQ (thoracic aorta, descending) and 021X4JQ (thoracic aorta, ascending/arch).

The same procedure with a different approach is coded 02170JQ (open).

With a different device, use 021748Q (zooplastic tissue), 021749Q (autologous venous tissue), 02174AQ (autologous arterial tissue), 02174KQ (nonautologous tissue substitute) and 02174ZQ (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.
