About 02LR4DZ

02LR4DZ is the ICD-10-PCS code for a occlusion procedure on the left pulmonary artery using a percutaneous endoscopic approach with intraluminal 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 02LH4DZ (pulmonary valve), 02LP4DZ (pulmonary trunk), 02LQ4DZ (right pulmonary artery), 02LS4DZ (right pulmonary vein), 02LT4DZ (left pulmonary vein) and 02LV4DZ (superior vena cava).

The same procedure with a different approach is coded 02LR0DZ (open) and 02LR3DZ (percutaneous).

With a different device, use 02LR4CZ (extraluminal device) and 02LR4ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It was added in FY2018, effective October 1, 2017.
