About 02LQ4CZ

02LQ4CZ is the ICD-10-PCS code for a occlusion procedure on the right pulmonary artery 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), 02LR4CZ (left pulmonary artery), 02LS4CZ (right pulmonary vein), 02LT4CZ (left pulmonary vein) and 02LV4CZ (superior vena cava).

The same procedure with a different approach is coded 02LQ0CZ (open) and 02LQ3CZ (percutaneous).

With a different device, use 02LQ4DZ (intraluminal device) and 02LQ4ZZ (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.
