About 02LH4ZZ

02LH4ZZ is the ICD-10-PCS code for a occlusion procedure on the pulmonary valve using a percutaneous endoscopic approach. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to creation of conduit between right ventricle and pulmonary artery, the ICD-9-CM procedure title it maps to (35.92).

For a different body part, codes include 02LP4ZZ (pulmonary trunk), 02LQ4ZZ (right pulmonary artery), 02LR4ZZ (left pulmonary artery), 02LS4ZZ (right pulmonary vein), 02LT4ZZ (left pulmonary vein) and 02LV4ZZ (superior vena cava).

The same procedure with a different approach is coded 02LH0ZZ (open) and 02LH3ZZ (percutaneous).

With a different device, use 02LH4CZ (extraluminal device) and 02LH4DZ (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 FY2017, effective October 1, 2016.
