Why is the 72146 rate in Suburban Chicago, IL different from the national amount?
The national figure is a GPCI 1.000 baseline, not an amount any provider is paid. This locality's geographic practice cost indices—work 1.007, practice expense 1.027, malpractice 1.772—scale each RVU component before the conversion factor is applied, which is why the Suburban Chicago, IL amount is higher than the $190.39 baseline.

Computed from the CMS Medicare Physician Fee Schedule Q4 2026 release: this code's RVUs from the relative value file, multiplied by payment locality 06102-15's GPCIs, then by the 2026 conversion factor of $33.4009. ZIP coverage from the CMS ZIP-to-locality crosswalk, Q4 2026 release. Past releases are never edited, so an amount for an earlier quarter always matches what CMS published for it. Coverage and coding correctness are outside this calculation.
