- How many surgeons perform Lumbar Fusion — Posterior in Illinois?
- 25 Illinois providers billed Medicare for Lumbar Fusion — Posterior (CPT 22612) in CY2024. CMS suppresses providers with 10 or fewer Medicare patients, so the true count is somewhat higher.
- Where does this data come from?
- CMS Medicare Physician & Other Practitioners (fee-for-service Part B claims, CY2024, released May 2026) and CMS Open Payments. Both are official U.S. federal datasets.
