About 027R34T

027R34T is the ICD-10-PCS code for a dilation procedure on the left pulmonary artery using a percutaneous approach with intraluminal device, drug-eluting (qualifier: ductus arteriosus). In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other repair of heart and pericardium, the ICD-9-CM procedure title it maps to (37.49).

The same procedure with a different approach is coded 027R04T (open) and 027R44T (percutaneous endoscopic).

With a different device, use 027R3DT (intraluminal device) and 027R3ZT (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), DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Major Cardiovascular Procedures” and “Other O.R. Procedures for Injuries”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
