| CPT3 | Description | Work RVUs | Total RVUs | 2025 Medicare National Average Payment |
|---|---|---|---|---|
| 52353 | Cystourethroscopy, with ureteroscopy and/or pyeloscopy; with lithotripsy (ureteral catheterization is included) | 7.50 | 11.60 | $375 |

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.

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.
