CPT Codes For Other Renal Introduction (Injection/Change/Removal) Procedures

Below is a list summarizing the CPT codes for other renal introduction (injection/change/removal) procedures.

CPT Code 50390

CPT 50390 describes percutaneous aspiration and/or injection of a renal cyst or pelvis by a needle.

CPT Code 50391

CPT 50391 describes the instillation of therapeutic agents into the renal pelvis and/or ureter through an established nephrostomy, pyelostomy, or ureterostomy tube, such as anticarcinogenic or antifungal agents.

CPT Code 50396

CPT 50396 describes manometric studies conducted through a nephrostomy, pyelostomy tube, or indwelling ureteral catheter.

CPT Code 50430

CPT 50430 describes a procedure for injection of an antegrade nephrostogram and/or ureterogram, complete with diagnostic imaging guidance (e.g., ultrasound and fluoroscopy) and all associated radiological supervision and interpretation, as well as new access.

CPT Code 50431

CPT 50431 describes a procedure for injecting an antegrade nephrostogram and/or ureterogram, complete with diagnostic imaging guidance (e.g., ultrasound and fluoroscopy) and all associated radiological supervision and interpretation using existing access.

CPT Code 50432

CPT 50432 describes the placement of a nephrostomy catheter, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (e.g., ultrasound and/or fluoroscopy), and all associated radiological supervision and interpretation.

CPT Code 50433

CPT 50433 describes the placement of a nephroureteral catheter, percutaneous, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (e.g., ultrasound and/or fluoroscopy), all associated radiological supervision and interpretation, and new access.

CPT Code 50434

CPT 50434 describes the conversion of a nephrostomy catheter to a nephroureteral catheter, percutaneous, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (e.g., ultrasound and/or fluoroscopy) and all associated radiological supervision and interpretation, via pre-existing nephrostomy tract.

CPT Code 50435

CPT 50435 describes the exchange of a nephrostomy catheter, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (e.g., ultrasound and/or fluoroscopy), and all associated radiological supervision and interpretation.

CPT Code 50436

CPT 50436 describes percutaneous dilation of an existing tract for an endourologic procedure, including imaging guidance, radiological supervision and interpretation, and postprocedure tube placement when performed.

CPT Code 50437

CPT 50437 describes the dilation of an existing tract, percutaneous, with imaging guidance, radiological supervision and interpretation, and postprocedure tube placement when performed, including new access into the renal collecting system.
