About 0TT48ZZ

0TT48ZZ is the ICD-10-PCS code for a resection procedure on the left kidney pelvis using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to partial nephrectomy, the ICD-9-CM procedure title it maps to (55.4).

For a different body part, codes include 0TT38ZZ (right kidney pelvis), 0TT68ZZ (right ureter), 0TT78ZZ (left ureter), 0TTB8ZZ (bladder), 0TTC8ZZ (bladder neck) and 0TTD8ZZ (urethra).

The same procedure with a different approach is coded 0TT40ZZ (open), 0TT44ZZ (percutaneous endoscopic) and 0TT47ZZ (via natural or artificial opening).

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.
