RVUs and rates listed are based on Calendar Year 2026 Medicare Physician Fee Schedule2

CPT3 Description Work RVUs Total RVUs 2026 Medicare National Payment
52353 Cystourethroscopy, with ureteroscopy and/or pyeloscopy; with lithotripsy (ureteral catheterization is included) 7.31 10.30 $344

If the physician believes the work of a particular case is above a standard ureteroscopy, possibly warranting additional payment, refer to individual payer guidelines regarding the correct use of Modifier 22 or the use of the urology unlisted code (CPT 53899). Whether either option is appropriate depends on the specifics of the individual case, physician and coder discretion, and/or payer guidelines. Note that clinical documentation in the operative note must substantiate the use of Modifier 22 or the unlisted code. Consult your Calyxo Reimbursement Manager to discuss billing and coding for complex cases.

**C1747 is the device code, representing a disposable ureteroscope, that must appear on the Medicare hospital outpatient (but not the ASC) claim to capture all charges associated with the Steerable Ureteral Renal Evacuation procedure using the CVAC System. There is no additional (i.e., “pass-through”) payment for this code beginning January 1, 2026.

Contact your Calyxo Reimbursement Manager for additional information or assistance.

Frequently Used Modifiers

Modifier Description Notes
50 Bilateral Procedure Indicates procedure was performed on both sides of the body. Procedure will usually be paid at 150% of the single procedure code by Medicare.
52 Reduced Procedure Indicates only a portion of the procedure was completed. Procedure will usually be paid at a 50% reduction of unmodified code by Medicare.
58 Staged Procedure Indicates that the performance of a procedure or service during the postoperative period was either: Planned prospectively at the time of the original procedure (i.e., staged); more extensive than the original procedure; or for the therapy following a surgical procedure. Procedure will usually be paid at 100%.

Prior Authorization Process for CVAC System

Prior authorization is recommended for commercial insurance, Medicare Advantage, and Medicaid. It is not required for traditional fee-for-service Medicare.

Submit a prior authorization request for CPT 52353 or 52356 for Physician and HCPCS Code C9761 for Facility. When prior authorizing C9761, make clear to the insurance company that this code is being authorized on behalf of the facility and not the physician. C9761 is a facility-only code. Failure to stipulate that the C9761 is a prior authorization for the facility and not the physician may result in a preventable denial.
