About 0TL44ZZ

0TL44ZZ is the ICD-10-PCS code for a occlusion procedure on the left kidney pelvis 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 operations on kidney, the ICD-9-CM procedure title it maps to (55.99).

For a different body part, codes include 0TL34ZZ (right kidney pelvis), 0TL64ZZ (right ureter), 0TL74ZZ (left ureter), 0TLB4ZZ (bladder), 0TLC4ZZ (bladder neck) and 0TLD4ZZ (urethra).

The same procedure with a different approach is coded 0TL40ZZ (open), 0TL43ZZ (percutaneous), 0TL47ZZ (via natural or artificial opening) and 0TL48ZZ (via natural or artificial opening endoscopic).

With a different device, use 0TL44CZ (extraluminal device) and 0TL44DZ (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for DRG 656 (Kidney and Ureter Procedures for Neoplasm with MCC), DRG 657 (Kidney and Ureter Procedures for Neoplasm with CC), DRG 658 (Kidney and Ureter Procedures for Neoplasm without CC/MCC), DRG 659 (Kidney and Ureter Procedures for Non-Neoplasm with MCC), DRG 660 (Kidney and Ureter Procedures for Non-Neoplasm with CC) and DRG 661 (Kidney and Ureter Procedures for Non-Neoplasm without CC/MCC), under the surgical categories “”, “Kidney and Ureter Procedures for Non-Neoplasm”, “Other O.R.
