About 0T940ZX

0T940ZX is the ICD-10-PCS code for a drainage procedure on the left kidney pelvis using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to open biopsy of kidney, the ICD-9-CM procedure title it maps to (55.24).

The same procedure with a different approach is coded 0T943ZX (percutaneous), 0T944ZX (percutaneous endoscopic), 0T947ZX (via natural or artificial opening) and 0T948ZX (via natural or artificial opening endoscopic).

Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R.
