Frequently asked questions
- How many surgeons perform Sacral Neuromodulation Lead Placement in Washington?
- 8 Washington providers billed Medicare for Sacral Neuromodulation Lead Placement (CPT 64561) in CY2024. CMS suppresses providers with 10 or fewer Medicare patients, so the true count is somewhat higher.
