About 021Q0KA

021Q0KA is the ICD-10-PCS code for a bypass procedure on the right pulmonary artery using an open approach with nonautologous tissue substitute (qualifier: innominate 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 021P0KA (pulmonary trunk), 021R0KA (left pulmonary artery), 021W0KA (thoracic aorta, descending) and 021X0KA (thoracic aorta, ascending/arch).

The same procedure with a different approach is coded 021Q4KA (percutaneous endoscopic).

With a different device, use 021Q08A (zooplastic tissue), 021Q09A (autologous venous tissue), 021Q0AA (autologous arterial tissue), 021Q0JA (synthetic substitute) and 021Q0ZA (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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