CPT Code for Laparoscopic Removal of Ureteral Stones
The correct CPT code for removal of ureteral stones via laparoscopy is 50945.
Understanding CPT Code Selection for Ureteral Stone Removal
Laparoscopic ureterolithotomy (CPT code 50945) is the appropriate code for reporting the laparoscopic removal of ureteral stones. This code specifically describes the laparoscopic approach for removing stones from the ureter.
Rationale for Code Selection
The American Urological Association guidelines clearly indicate that laparoscopic ureterolithotomy is a treatment option for ureteral stones, particularly in cases where:
- SWL (shock wave lithotripsy) and URS (ureteroscopy) have failed or are unlikely to succeed 1
- The patient has very large (>15 mm), impacted, and/or multiple ureteral stones 1
- The stones are located in the proximal or mid-ureter 1
Alternative Treatment Approaches and Their CPT Codes
It's important to understand how the laparoscopic approach differs from other treatment modalities:
- Ureteroscopy with stone removal (52352) - This is an endoscopic approach through the urethra and bladder to access the ureter 2
- Ureteroscopy with lithotripsy (52353) - Similar to 52352 but includes fragmentation of the stone
- Shock wave lithotripsy (50590) - External fragmentation of stones using shock waves
- Percutaneous nephrolithotomy (50080/50081) - Direct percutaneous access to the kidney for stone removal
Clinical Considerations for Laparoscopic Approach
While laparoscopic ureterolithotomy (50945) is highly effective with success rates of 93-96% 3, 4, it is generally not considered first-line therapy due to:
- Greater invasiveness compared to SWL and URS 1
- Longer recovery time 1
- Higher risk of complications 1
- Longer operative duration 5, 6
When to Consider Laparoscopic Approach
Laparoscopic ureterolithotomy should be considered in specific scenarios:
- After failure of less invasive approaches (SWL, URS) 1
- For stones larger than 15-20mm in the proximal ureter 3, 4, 6
- When the upper urinary tract is not amenable to retrograde URS (e.g., in patients with urinary diversion or renal transplants) 1
- When expertise in laparoscopic techniques is available 1
Conclusion
When documenting and coding for laparoscopic removal of ureteral stones, CPT code 50945 is the appropriate selection. This procedure, while highly effective, is typically reserved for cases where less invasive approaches have failed or are unlikely to succeed.
