About 04LN4ZZ

04LN4ZZ is the ICD-10-PCS code for a occlusion procedure on the left popliteal artery 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 other surgical occlusion of vessels, lower limb arteries, the ICD-9-CM procedure title it maps to (38.88).

For a different body part, codes include 04L04ZZ (abdominal aorta), 04L14ZZ (celiac artery), 04L24ZZ (gastric artery), 04L34ZZ (hepatic artery), 04L44ZZ (splenic artery), 04L54ZZ (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04LN0ZZ (open) and 04LN3ZZ (percutaneous).

With a different device, use 04LN4CZ (extraluminal device) and 04LN4DZ (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC), DRG 254 (Other Vascular 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 Vascular Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
