About 02164AP
02164AP is the ICD-10-PCS code for a bypass procedure on the right atrium using a percutaneous endoscopic approach with autologous arterial tissue (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 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 02174AP (left atrium), 021K4AP (right ventricle), 021L4AP (left ventricle), 021V4AP (superior vena cava), 021W4AP (thoracic aorta, descending) and 021X4AP (thoracic aorta, ascending/arch).
The same procedure with a different approach is coded 02160AP (open).
With a different device, use 021648P (zooplastic tissue), 021649P (autologous venous tissue), 02164JP (synthetic substitute), 02164KP (nonautologous tissue substitute) and 02164ZP (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.
