About 02LT4CZ

02LT4CZ is the ICD-10-PCS code for a occlusion procedure on the left pulmonary vein using a percutaneous endoscopic approach with extraluminal device. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other surgical occlusion of vessels, thoracic vessels, the ICD-9-CM procedure title it maps to (38.85).

For a different body part, codes include 02LH4CZ (pulmonary valve), 02LP4CZ (pulmonary trunk), 02LQ4CZ (right pulmonary artery), 02LR4CZ (left pulmonary artery), 02LS4CZ (right pulmonary vein) and 02LV4CZ (superior vena cava).

The same procedure with a different approach is coded 02LT0CZ (open) and 02LT3CZ (percutaneous).

With a different device, use 02LT4DZ (intraluminal device) and 02LT4ZZ (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.
