- How many surgeons perform Lumbar Fusion — Combined (TLIF/PLIF) in Colorado?
- 43 Colorado providers billed Medicare for Lumbar Fusion — Combined (TLIF/PLIF) (CPT 22633) in CY2024. CMS suppresses providers with 10 or fewer Medicare patients, so the true count is somewhat higher.

- 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.

- No — it covers traditional Medicare only (no Medicare Advantage, commercial, or Medicaid claims). Absolute volumes undercount total practice, but the ranking of high- vs low-volume surgeons is a strong targeting signal.
