When a patient reports a bladder stone, the urologist first checks the size of the stone.
Then, the doctor breaks the stone and removes it from the body. This procedure is called cystourethroscopy with litholapaxy. The doctor uses a cystoscope, which passes through the urethra. The doctor uses laser or ultrasound to break the stone and washes out the pieces.
Billing for this procedure can be challenging. You must match the correct CPT code with proper documentation.
The size of the stone and the complexity of the procedure both matter. You must review the full case before selecting a code.
Urology billers use:
- CPT 52317 for stones 2.5 cm or smaller
- CPT 52318 for stones larger than 2.5 cm
Correct coding helps you avoid claim denials and receive faster payment. This guide explains how to use CPT 52317 correctly.
Understanding CPT Code 52317
CPT 52317 describes a procedure where the doctor:
- Uses a scope to enter the bladder
- Breaks a small stone (less than 2.5 cm)
- Removes the stone pieces
The doctor uses a cystoscope and special tools to complete the procedure. The complexity depends on the size and condition of the stone.
Common Scenarios for CPT 52317
Scenario 1: Single Small Stone (Simple Case)
A patient feels pain during urination. An X-ray shows one bladder stone measuring 1.5 cm.
The doctor:
- Performs cystoscopy
- Uses a laser to break the stone
- Removes fragments using an Ellik aspirator
In this case, the biller should use CPT 52317 because:
- The stone is small
- The procedure is simple
Scenario 2: Multiple Small Stones
A patient has several small bladder stones, all under 2.5 cm. The doctor removes all stones in one session.
In this case, you should:
- Focus on procedure complexity, not just the number of stones
- Follow payer guidelines
You should document:
- Number of stones
- Total stone size
- Method used (laser, ultrasound, etc.)
- Surgery time
- Any difficulties
If the procedure remains simple, use CPT 52317.
If the case becomes complex (longer time or technical difficulty), you may use CPT 52318 instead.
Always check payer rules before making your final decision.
When to Use CPT Code 52317
Use CPT 52317 when:
- The doctor performs cystourethroscopy
- The stone is 2.5 cm or smaller
- The doctor breaks the stone and removes it in the same session
- The procedure is simple
- The stone is in the bladder (or urethra/prostatic urethra)
In short, use this code when the doctor removes a small bladder stone using a cystoscope.
When NOT to Use CPT 52317
Do not use CPT 52317 when:
- The stone is larger than 2.5 cm → use 52318
- The doctor performs open surgery (e.g., cystotomy) → use a different code like 51050
- The service involves ureter or kidney stones → use other codes (e.g., 52353)
Also remember:
- Routine services like catheter placement, cystoscopy exam, and bladder irrigation are included in this code
- Do not bill these separately
If you perform a separate service, you must:
- Check NCCI edits
- Follow payer bundling rules
- Provide clear documentation
Documentation Requirements for CPT 52317
Clear documentation helps you get paid without delays.
You should document:
- The full procedure (cystourethroscopy with litholapaxy)
- Stone size (must be under 2.5 cm)
- Stone location (bladder)
- Method used (laser, ultrasonic, etc.)
- Findings from bladder and urethra inspection
If the doctor performs additional procedures:
- Document each location and tool used
- Use modifiers when needed
If you perform a separate, unrelated service, you may use modifier -XU with proper documentation.
Modifiers for CPT 52317
Use modifiers only when documentation supports them.
Modifier 59 (Separate Service)
Use this modifier only when no better option exists. Try to use more specific modifiers like XS, XE, XP, or XU.
Modifier 22 (Extra Work)
Use Modifier 22 when the procedure:
- Takes much more time
- Requires extra effort
The doctor must clearly explain:
- Why the procedure was difficult
- What caused the extra work (e.g., anatomy, multiple attempts)
Estimated Medicare Payment for CPT 52317 (2026)
Payment depends on location and setting.
- Office (Non-Facility): $850–$900
- Facility (Hospital/ASC): $300–$1,000
Key factors:
- Work RVU (time and skill required)
- Practice expense (depends on location)
Always check the CMS Physician Fee Schedule for updated rates.
Commercial Insurance Rates
Commercial insurance companies set their own rates.
Most pay:
- 1.1x to 1.6x Medicare rates
Estimated range:
- $900 to $1,600 (in-network)
- $1,800+ (out-of-network, varies widely)
Final payment depends on:
- Contract terms
- Fee schedule
- Negotiated rates
Bundled Services (Important)
CPT 52317 already includes:
- Catheter placement
- Cystoscopy exam
- Bladder irrigation
Do not bill these services separately. The payer will deny them.
Before submitting a claim:
- Review NCCI guidelines
- Check payer policies
This step helps you avoid delays and rejections.
Conclusion
Using CPT 52317 correctly helps urologists get paid on time and avoids claim denials. Always check the stone size, procedure complexity, and payer rules before coding. Document every detail clearly, including stone location, size, and method of removal. Use modifiers only when the service is separate or requires extra effort.
Remember that routine steps like catheter placement and bladder irrigation are already included. Accurate coding and complete documentation make billing smooth, ensure proper reimbursement, and reduce delays. Following these steps helps your clinic manage claims efficiently and keeps insurance approvals fast and accurate.
