About 027L0ZZ
027L0ZZ is the ICD-10-PCS code for a dilation procedure on the left ventricle using an open approach. 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).
For a different body part, codes include 02700ZZ (coronary artery, one artery), 02710ZZ (coronary artery, two arteries), 02720ZZ (coronary artery, three arteries), 02730ZZ (coronary artery, four or more arteries), 027F0ZZ (aortic valve), 027G0ZZ (mitral valve) and 11 more.
The same procedure with a different approach is coded 027L3ZZ (percutaneous) and 027L4ZZ (percutaneous endoscopic).
With a different device, use 027L04Z (intraluminal device, drug-eluting) and 027L0DZ (intraluminal 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 was added in FY2018, effective October 1, 2017.
