Percutaneous Procedure CPT Code Update

Coding Corner Percutaneous Procedure CPT Code Update Jonathan Rubenstein, MD Chesapeake Urology Associates, Baltimore, MD [Rev Urol. 2016;18(1):38-43 doi: 10.3909/riu0707] ® © 2016 MedReviews , LLC A number of new and revised Common Procedural Technology (CPT®; American Medical Association, Chicago, IL) codes pertaining to percutaneous renal access, renal drainage, and diagnostic and therapeutic procedures performed percutaneously were introduced on January 1, 2016. In addition, several commonly used CPT codes for percutaneous renal procedures were eliminated. The new and revised CPT codes for percutaneous procedures became necessary as several of the older procedure codes were being billed with the radiologic supervision and interpretation code in over 75% of cases and needed to be bundled together. In addition, there was a need for greater specificity due to different work requirements of different procedures that were previously captured within one code. The new CPT codes for percutaneous renal access and drainage now include radiologic supervision and interpretation in the description. The new codes allow for more streamlined and simplified coding, and eliminate the prior need for multiple codes for a procedure that now can be captured with one code, or with fewer codes, due to their increased specificity. Urologists and interventional radiologists who perform percutaneous renal procedures must have a comprehensive understanding of these changes and the new, established, and eliminated codes to ensure accurate documentation and accurate coding. New Percutaneous Renal Access and Drainage Codes New Codes CPT 50430 Injection procedure for antegrade nephrostogram and/or ureterogram, complete diagnostic procedure including imaging guidance and all associated radiologic supervision and interpretation, new access; and CPT 50431 . . . through existing access (Table 1). Eliminated Code CPT 50394 Injection procedure for pyelography through nephrostomy or pyelostomy tube or indwelling catheter. CPT 50394 (diagnostic injection) was being billed with CPT 74425 (radiologic supervision and interpretation) in more than 75% of cases, which necessitated a new combination code. The two new codes include radiologic supervision and interpretation as part of the description, so an interpretation code should not be separately coded. CPT 50430 should be used when a new access is placed for injection, and CPT 50431 should be used if the injection is performed through an access that already exists. These codes should not be reported more than once per accessed side, but can be billed with an appropriate modifier (if needed) if performed on opposite sides.

New Code CPT 50432 Placement of nephrostomy catheter, percutaneous, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiologic supervision and interpretation. Eliminated Code CPT 50392 Introduction of catheter into renal pelvis. CPT 50392 (nephrostomy tube placement) was being billed with CPT 74475 in more than 75% of cases, so a new code was needed to bundle the procedures together. As image supervision and interpretation are included in CPT 50432, an interpretation code should not be used separately. Procedures performed on the opposite side or in a different location within the kidney can be coded using the appropriate modifier. Injection for nephrostogram (CPT 50430 and CPT 50431) should not be coded if performed on the same side. New Codes CPT 50433 Placement of nephroureteral catheter, percutaneous, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiologic supervision and interpretation, new access. CPT 50693 Placement of ureteral stent, percutaneous, including diagnostic nephrostogram and/ or ureterogram when performed, imaging guidance (eg, ultrasound and/or fluoroscopy), and all associated radiologic supervision and interpretation; preexisting nephrostomy tract. CPT 50694 . . . via a new access without a separate nephrostomy catheter. CPT 50695 . . . via new access with a separate nephrostomy catheter. Eliminated Code CPT 50393 Introduction of ureteral catheter or stent into ureter through renal pelvis for drainage and/or injection, percutaneous. Replacement codes for CPT 50393 were deemed necessary due to the frequent coding with an interpretation code and due to need for increased specificity. Dividing this one code into four unique codes achieved more specificity and more accurate work values for payment. The placement of a nephroureteral catheter (CPT 50433) requires more work and effort and, therefore, has higher work relative value units (RVUs) than nephrostomy tube placement (CPT 50432). The three codes for placing a ureteral stent through a percutaneous approach are divided on whether there is a preexisting nephrostomy tract (CPT 50693), whether new access is achieved but no nephrostomy remains (CPT 50694), or whether new access is achieved and a nephrostomy is also placed (CPT 50695). One should not bill for an antegrade nephrostogram (CPT 50430 or CPT 50431) or the placement of a nephrostomy (CPT 50432) with any of these codes if performed on the same side. New Codes CPT 50434 Convert nephrostomy catheter to nephroureteral catheter, percutaneous, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiologic supervision and interpretation, via preexisting nephrostomy tract. CPT 50435 Exchange nephrostomy catheter, percutaneous, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiologic supervision and interpretation. Eliminated Code CPT 50398 Change of nephrostomy or pyelostomy tube. CPT 50398 was typically billed along with an interpretation code such as CPT 74425, making a new bundled code necessary. The two new codes include converting a nephrostomy to nephroureteral catheter (CPT 50434), which requires more work than exchanging a nephrostomy catheter (CPT 50435). Once again, one should not bill for an antegrade nephrostogram or placing or replacing a nephrostomy separately on the same side. Exchanging of a nephroureteral catheter for a new nephroureteral catheter is already captured using the already established CPT 50387 (Table 2), although the terminology is updated, as previous language described a transnephric stent. This code includes radiologic supervision and interpretation. The removal and replacement of an externally accessible ureteral stent (such as an ileal conduit stent) is captured using CPT 50688. New Add-on Codes for Percutaneous Renal Procedure In addition to new and updated percutaneous renal access and drainage codes, three new percutaneous 40 • Vol. 18 No. 1 • 2016 • Reviews in Urology 4004170006_RIU0707.indd 40 05/04/16 3:49 pm Percutaneous Procedure CPT Code Update TABLE 2 Other Selected Percutaneous Renal Drainage CPT Codes With Work RVU and Coding Instructions CPT Code RVU Description Instructions 50382 5.5 Radiologic interpretation included 50387 2.0 Removal (via snare/capture) and replacement of internally dwelling ureteral stent via percutaneous approach, including radiologic supervision and interpretation Removal and replacement of externally accessible nephroureteral catheter (eg, external/internal stent) requiring fluoroscopic guidance, including radiologic supervision and interpretation 50389 1.1 Removal of nephrostomy tube, requiring fluoroscopic guidance (eg, with concurrent indwelling ureteral stent) 50395 3.37 Introduction of guide into renal pelvis and/or ureter with dilation to establish nephrostomy tract, percutaneous 50688 1.2 Change of ureterostomy tube or externally accessible ureteral stent via ileal conduit Excludes removal and replacement of ureteral stent through ileal conduit (CPT 50688) Excludes nephrostomy tube removal without fluoroscopic guidance Do not report with CPT 50382, 50384, 50432, 50433; excludes renal endoscopy (50551-50561) Radiology crosswalk: 75984 CPT, Common Procedural Technology; RVU, relative value unit. renal procedural codes were introduced (Table 3). CPT 50705 Ureteral embolization or occlusion, including imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiologic supervision and interpretation (list separately in addition to code for primary procedure); CPT 50706 Balloon dilation, ureteral stricture, including imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiologic supervision and interpretation (list separately in addition to code for primary procedure); and CPT 50606 Endoluminal biopsy of ureter and/or renal pelvis, nonendoscopic, including imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiologic supervision and interpretation (list separately in addition to code for primary procedure). The three new percutaneous renal procedural codes listed are considered “add-on” codes. For accurate coding, the access code for the procedure should be billed first, and these add-on codes billed afterward. For percutaneous biopsy of a renal pelvis or ureter lesion, CPT 50606 should only be billed if direct visualization, such as using a nephroscope, is not performed. If the biopsy is performed under direct vision, CPT 50555 is used if performed through a nephrostomy and CPT 50955 used if performed through an established percutaneous ureterostomy (Table 4). Note that CPT 50574 and CPT 50974 are for open procedures (such as flank incision) to access the kidney and ureter for biopsy. Similarly, for ureteral dilation, CPT 50706 should only be used if endoscopy is not performed. If endoscopy is performed for ureter dilation then CPT 50553 should be reported if performed through a nephrostomy and CPT 50953 if through a ureterostomy (Table 4). CPT 50572 and CPT 50972 are used for open approaches to access the kidney and ureter (such as using a flank incision) Common Scenarios for Billing for Urology When billing for services provided, the first and most important step is accurate documentation. With the increased specificity of the currently available CPT codes, the provider who performs the procedure needs to specifically and accurately document in the note the presence or absence of access prior to initiation of the case; any new access that may be achieved during the case; the laterality; the procedure performed; and detail which tubes (if any) remain indwelling after the case. Note that the code choices and rationale discussed herein are for advice only, are the most accurate codes available for specific scenarios, but do not guarantee payment.

Local insurer rules, including bundling and modifiers, should always be followed. This is not an exhaustive list of all potential scenarios, but should serve as a starting point for proper coding. Scenario 1: Percutaneous Nephrolithotomy With Percutaneous Access Already in Place A commonly encountered scenario for urologists is the performance of percutaneous nephrolithotomy for a stone . 2 cm (CPT 50081) in a patient with a nephrostomy tube already in place. In addition to billing CPT 50081, the following CPT codes should be chosen: if the urologist uses the existing tract, performs the case, and replaces a nephrostomy at the end of the case, it is most accurate to also bill CPT 50435 (removal and replacement of nephrostomy). If the surgeon converts the existing nephrostomy to a nephroureteral catheter at the end of the case, then the addition code is CPT 50434 (convert nephrostomy to nephroureteral catheter via preexisting nephrostomy tract). If the patient has an antegrade double-J stent placed but is left without a nephrostomy, then CPT 50693 (placement of ureteral stent through preexisting nephrostomy tract) should be billed. If both a double-J stent and nephrostomy are placed, then both CPT 50693 and CPT 50435 should be billed (CPT 50693 has higher RVUs so is placed above CPT 50435). If the urologist places a second (or third, or fourth) access in addition to the existing access, then the following CPT codes should be added: CPT 50395 (Introduction of guide into renal pelvis and/or ureter with dilation to establish nephrostomy tract, percutaneous) if the access was used but no nephrostomy remained in that access or CPT 50432 (Placement of nephrostomy catheter, percutaneous, including 42 • Vol. 18 No. 1 • 2016 • Reviews in Urology 4004170006_RIU0707.indd 42 05/04/16 3:49 pm Percutaneous Procedure CPT Code Update TABLE 4 Selected Percutaneous Biopsy and Dilation CPT Codes With Work RVUs and Coding Instructions CPT Code RVU Description Instructions 50555 6.5 Renal endoscopy through established nephrostomy or pyelostomy, with or without irrigation, instillation, or ureteropyelography, exclusive of radiologic service; with biopsy 50955 6.74 Ureteral endoscopy through established ureterostomy, with or without irrigation, instillation, or ureteropyelography, exclusive of radiologic service; with biopsy 50553 5.98 50953 6.23 Renal endoscopy through established nephrostomy or pyelostomy, with or without irrigation, instillation, or ureteropyelography, exclusive of radiologic service; with ureteral catheterization, with or without dilation of ureter Ureteral endoscopy through established ureterostomy, with or without irrigation, instillation, or ureteropyelography, exclusive of radiologic service; with ureteral catheterization, with or without dilation of ureter Do not report with imageguided biopsy ureter/renal pelvis without endoscopic guidance (CPT 50606) Do not report with imageguided biopsy of ureter and/or renal pelvis without endoscopic guidance (CPT 50606) Do not report with imageguided ureter dilation without endoscopic guidance (CPT 50706) Do not report with imageguided ureter dilation without endoscopic guidance (CPT 50706) CPT, Common Procedural Technology; RVU, relative value unit. diagnostic nephrostogram and/or ureterogram when performed, imaging guidance [eg, ultrasound and/or fluoroscopy] and all associated radiologic supervision and interpretation) if a nephrostomy remains in place. In these situations, a modifier (such as Modifier 59 or Modifier XS) may be needed. It is reasonable to bill each code per each separate renal access, with the appropriate modifier. Scenario 2: Percutaneous Nephrolithotomy in Which the Urologist Achieves His or Her Own Access Another common scenario occurs when a urologist places his or her own access for a percutaneous nephrolithotomy. If the urologist performs a cystoscopy with ureteral catheter placement with retrograde pyelogram with interpretation, the CPT 52005 and CPT 74420 should be chosen. If the procedure is performed (CPT 50081) and the patient remains tubeless at the end of the case, CPT 50395 (Introduction of guide into renal pelvis and/or ureter with dilation to establish nephrostomy tract, percutaneous) should be chosen, in addition to the stone removal procedure code. If a nephrostomy is used for postoperative drainage, CPT 50432 (nephrostomy tube placement) should be used. If a nephroureteral stent is placed, then CPT 50433 is the correct choice. If a ureteral stent is placed, CPT 50694 should be used if the patient remains tubeless, and CPT 50695 should be used if the patient has a stent and nephrostomy. Additional access sites at unique locations within the same kidney should with billed with the appropriate modifier (such as Modifier 59 or Modifier XS) if necessary, based on insurance carrier rules. Conclusions The new CPT codes for percutaneous renal access, drainage, and diagnostic and therapeutic procedures have increased the specificity of coding and billing, but have also streamlined the coding process. It is vitally important to understand the current CPT codes available to most accurately document the procedure performed, and to submit the most accurate CPT codes for reimbursement purposes.
